Red Light Therapy for Hyperpigmentation: Can It Fade Dark Spots?

The Stubborn Spot Problem

You know that feeling when you're getting ready for an important meeting, and despite your carefully applied makeup, you can still see those dark patches staring back at you in the mirror? You're not imagining the frustration - hyperpigmentation affects roughly 90% of people at some point, cutting across every age group and skin tone.

Here's what makes it particularly maddening: those spots aren't just cosmetic. Research published in the Journal of Clinical and Aesthetic Dermatology reveals that visible hyperpigmentation impacts quality of life scores as significantly as acne or eczema. People report decreased professional confidence, reluctance to be photographed, and genuine anxiety about being seen without makeup.

Now enter red light therapy - the treatment currently flooding your social media feeds. Influencers are posting glowing selfies (literally), your coworker swears by her red light panel, and devices range from $79 wands to $2,000 full-body systems. The marketing promises are bold: "Fade dark spots naturally!" "Clinically proven results!" "The future of skincare!"

But here's the tension we need to address: Is this actually backed by solid science, or just exceptionally well-packaged wellness industry hype?

This guide cuts through the noise. We'll examine the actual research, compare red light therapy realistically to treatments your dermatologist might recommend, and help you determine whether investing time and money makes sense for your specific situation.

Why Red Light Therapy Is Having Its Moment

This isn't new technology - NASA studied it in the 1990s for wound healing. But several factors have converged to bring it mainstream:

The regulatory landscape is evolving. The FDA has expanded clearances for LED therapy beyond anti-aging to include acne treatment and inflammation. While not specific to hyperpigmentation, this signals growing acceptance of photobiomodulation as legitimate therapy.

The pandemic accelerated at-home treatments. When professional care became inaccessible, consumers invested in home devices. This market expansion pushed quality up and prices down.

Research is catching up to marketing claims. We now have peer-reviewed studies specifically examining red light's effects on pigmentation - not just anecdotal reports.

Traditional treatments have significant limitations. Harsh chemicals can damage skin barriers. Lasers risk worsening pigmentation, especially on darker skin. People are actively seeking gentler alternatives.

Let's separate the science from the sales pitch.

Understanding Hyperpigmentation: Why Those Dark Spots Won't Budge

Before evaluating whether red light therapy works, we need to understand exactly what we're treating and why it's so notoriously difficult.

What's Actually Happening in Your Skin

Hyperpigmentation is deceptively simple: overproduction of melanin, the pigment giving skin its color. Melanocytes - the cells producing melanin - go into overdrive in certain areas, creating visible dark patches or uneven tone.

But here's the complexity: melanin serves a protective function. When your skin senses damage (UV rays, inflammation, injury), melanocytes spring into action, producing melanin as defense. Those dark spots aren't just cosmetic annoyances - they're your skin's protective response that stuck around after the threat passed.

Think of it like a car alarm that won't turn off after the thief has left.

The Main Culprits

Sun Damage (Solar Lentigines) The most common form - "age spots" or "sun spots" appearing on chronically sun-exposed areas: face, hands, shoulders. Years of accumulated UV exposure cause melanocytes to produce pigment unevenly. They're generally flat, well-defined spots that don't fade in winter.

Hormonal Melasma Often called the "mask of pregnancy," melasma appears as larger patches of brown or gray-brown discoloration, typically symmetrically across cheeks, forehead, upper lip, and chin. Pregnancy, birth control pills, or hormone therapy can trigger it. It's notoriously stubborn and prone to recurrence - many experience improvement with treatment, only to have it return.

Post-Inflammatory Hyperpigmentation (PIH) The marks left after inflammation: acne breakouts, eczema flares, cuts, burns, or overly aggressive skincare. The inflammatory response triggers excess melanin production as part of healing. These marks appear exactly where the inflammation occurred and are generally darker in people with darker skin tones.

Age-Related Uneven Tone As skin ages, melanocyte distribution becomes increasingly uneven. Some areas overproduce pigment while others underproduce, creating that mottled appearance that ages the complexion more than wrinkles for many people.

Why Traditional Treatments Fall Short

Here's the frustrating reality: we have treatments, but none are perfect.

Hydroquinone is the prescription gold standard, inhibiting the enzyme necessary for melanin production. It's effective but controversial - long-term use can cause paradoxical darkening (ochronosis), particularly in darker skin. Many European countries have banned it. In the US, dermatologists recommend limiting use to 3-4 month cycles.

Retinoids accelerate cell turnover, gradually shedding pigmented cells. They work, but slowly - typically 12+ weeks before visible improvement. The adjustment period is rough: redness, peeling, increased sensitivity. Many quit before seeing results.

Chemical peels physically remove outer skin layers, taking pigmented cells with them. They can produce dramatic results but require downtime (literally peeling for days), multiple sessions ($150-300 each), and carry risks including infection and, ironically, PIH from the peel itself.

Laser treatments are most aggressive, using targeted light energy to break up pigment. They're highly effective for appropriate candidates but expensive ($500-2,000+ per session), require multiple sessions, involve significant downtime, and carry substantial risks for darker skin tones. Many dermatologists won't perform certain lasers on Fitzpatrick types IV-VI because the risk is too high.

The common thread? Treatments are harsh, expensive, risky for certain skin tones, or require extraordinary patience. They also share the rebound effect challenge.

The Rebound Effect

This is perhaps most demoralizing: you can do everything right, see improvement, then watch pigmentation return - sometimes worse than before.

Why? Most treatments address the symptom (visible pigment) without fully addressing underlying triggers. Without fanatical sun protection, UV exposure immediately triggers new melanin. If hormones caused your melasma, it'll return with your next pregnancy. If inflammation is your trigger, your next breakout creates new PIH.

Additionally, aggressive treatments themselves cause inflammation, triggering the very melanocytes you're trying to calm. It's a frustrating cycle leading people to try treatment after treatment, investing thousands of dollars and years of effort with inconsistent results.

This is where red light therapy enters: the need for gentler, safer options usable long-term without worsening risks.

But does the science support it?

Red Light Therapy 101: The Science Without Sales Pitch

What Red Light Therapy Actually Is

Red light therapy (RLT) - also called photobiomodulation or low-level light therapy - uses specific wavelengths in the red and near-infrared spectrum to stimulate cellular function. Unlike UV light (which damages DNA and causes cancer) or screen light (doing nothing therapeutic), red and near-infrared wavelengths penetrate skin tissue and interact with cells in specific, measurable ways.

The wavelengths that matter:

Red Light (630-670nm): Visible spectrum - the actual red glow you see. Penetrates 1-2mm into skin, reaching epidermis and upper dermis. Perfect for targeting surface-level concerns including melanin deposits in the epidermal layer.

Near-Infrared (810-850nm): Invisible to human eyes but crucial for therapy. Penetrates much deeper - 2-4cm into tissue - reaching deeper dermal layers, underlying blood vessels, even muscle. For hyperpigmentation, this addresses inflammation driving pigment production.

Both wavelengths matter because superficial hyperpigmentation sits in upper skin layers, but inflammation and cellular dysfunction perpetuating pigmentation often exist deeper. Using both addresses the problem from multiple depths.

The mechanism isn't magic. It's biophysics.

How Light Becomes Cellular Energy

Inside your cells are mitochondria - the "powerhouses" converting nutrients into ATP (adenosine triphosphate), the energy currency cells use for everything from repair to regeneration.

Within mitochondria is cytochrome c oxidase. This molecule absorbs red and near-infrared wavelengths, triggering beneficial cellular responses:

• Increased ATP production: More energy for repair and regeneration
• Enhanced cellular signaling: Improved communication coordinating healing
• Reduced oxidative stress: Neutralizing reactive oxygen species causing cellular damage
• Nitric oxide release: Improved blood flow and oxygen delivery
• Modulation of inflammatory pathways: Influencing pro- and anti-inflammatory signaling

Think of it this way: your cells are smartphones running low on battery. They work, but slowly and inefficiently. Red light therapy is plugging them in to charge. With more energy, cells perform maintenance and repair functions more effectively.

The Hyperpigmentation Connection

Tyrosinase downregulation: Tyrosinase is the rate-limiting enzyme in melanin production. Studies suggest red light therapy can reduce tyrosinase activity - essentially turning down melanin production volume. This doesn't happen immediately - it's gradual regulatory effect over weeks of consistent exposure.

Inflammatory modulation: Post-inflammatory hyperpigmentation happens because inflammation triggers melanocytes. By reducing overall skin inflammation, red light therapy prevents new PIH from forming and creates an environment where existing PIH fades more readily.

Improved circulation and cellular turnover: Enhanced blood flow brings more nutrients and oxygen while removing waste more efficiently. Increased cellular energy supports natural exfoliation, gradually replacing pigmented cells with fresh ones.

Collagen stimulation: While more relevant for anti-aging, improved collagen creates healthier overall skin architecture. Healthier skin responds better to treatments and maintains results longer.

Important caveat: These mechanisms are supported by cellular and animal studies. The leap from "this happens in a petri dish" to "this will fade your dark spots" is where things get murkier. The science establishes plausibility, but human clinical outcomes need focus.

Why Wavelength Precision Actually Matters

This is where cheap devices fail spectacularly.

Not all red light is therapeutic. Specific wavelengths matter enormously. A device emitting 600nm or 700nm light might look red, but it's not hitting absorption peaks triggering therapeutic responses. Cytochrome c oxidase has specific absorption peaks around 660nm and 850nm. Miss those peaks, and you're just giving your face a pretty red glow with no biological effect.

Cheap devices often emit broad-spectrum visible light with only small portions in therapeutic range. They're basically fancy mood lighting. This is why some people use red light therapy devices religiously and see zero results - they're not receiving therapeutic wavelengths at sufficient intensity.

Quality devices use LEDs specifically manufactured to emit tight wavelength ranges: 660nm ± 10nm for red, 850nm ± 10nm for near-infrared. This precision ensures you're actually getting wavelengths your cells can use.

Setting Realistic Expectations

Let's be clear about what red light therapy is NOT doing:

• Not physically removing pigmented skin layers like chemical peels
• Not breaking up pigment deposits with heat energy like lasers
• Not bleaching skin like hydroquinone
• Not suppressing melanin production as aggressively as prescription medications

What it IS doing: creating cellular conditions favoring gradual improvement - reduced inflammation, better cellular turnover, downregulated melanin production. This is slow, gentle modulation of your skin's natural processes, not dramatic intervention.

If you're imagining dramatic before-and-after photos after two weeks, you're setting yourself up for disappointment. What it might deliver - and this is what research explores - is modest, gradual improvement over months of consistent use, with a safety profile making it usable long-term without risks associated with aggressive treatments.

The Evidence: What Research Really Shows

Here's where we examine actual data. What happens when researchers take red light therapy into clinical trials and measure effects on human hyperpigmentation?

Fair warning: the science is genuinely interesting but also limited, preliminary, and sometimes contradictory. The truth occupies that frustrating middle ground where evidence is intriguing but not definitive.

Understanding Research Quality

Not all studies carry equal weight. The hierarchy from weakest to strongest:

• Anecdotal reports: Personal stories, influencer reviews. Worthless as scientific evidence.
• Case studies: One or few individuals documented. Interesting for hypothesis generation, prove nothing about broader effectiveness.
• Observational studies: Researchers observe without controlling variables. Better than anecdotes, but correlation doesn't equal causation.
• Randomized controlled trials (RCTs): Gold standard. Participants randomly assigned to treatment or control groups, results measured objectively.
• Systematic reviews/meta-analyses: Combine data from multiple studies. Most valuable when examining multiple high-quality RCTs.

For red light therapy and hyperpigmentation, we have mostly small RCTs and observational studies, with a few larger trials emerging. We don't yet have robust meta-analyses because research is relatively new and studies use different protocols, making direct comparison difficult.

The Industry Funding Reality

Many red light therapy studies are funded by device manufacturers. This doesn't automatically invalidate research, but introduces potential bias. Industry-funded studies are more likely to report positive results, use protocols favoring their specific device, and less likely to publish negative findings.

Most trustworthy evidence comes from independent academic research published in peer-reviewed dermatology journals.

What Research Shows: Melasma

Melasma is most-studied in red light therapy research, probably because it's particularly stubborn and patients are desperate for safe alternatives.

Canadian study using 940nm: A pilot study published in the Journal of Clinical and Aesthetic Dermatology evaluated pulsed photobiomodulation (940nm near-infrared) for melasma treatment in seven patients with bilateral dermal melasma over 12 weeks. The photobiomodulation-treated side showed statistically significant improvement in Melasma Area and Severity Index scores compared to the control side (p<0.001), demonstrating that dermal melasma can be significantly improved with pulsed photobiomodulation.

2024 Systematic Review: A 2024 integrative review examining photobiomodulation for melasma treatment identified nine relevant clinical studies. The review concluded that clinical studies suggest photobiomodulation effectively reduces melasma-associated hyperpigmentation. Specific wavelengths including red light (630 nm), amber (585 and 590 nm), and infrared (830 and 850 nm) at radiant exposures between 1 and 20 J/cm² were found to exert modulatory effects on tyrosinase activity, gene expression, and protein synthesis of melanocytic pathway components, significantly reducing melanin content

What this tells us: For melasma, evidence suggests red light provides modest but meaningful additional improvement when combined with standard treatments. Probably not effective as standalone treatment for moderate-severe melasma, but appears to enhance other therapies.

Realistic expectations: If you have melasma, red light therapy might be useful addition to your treatment plan, potentially reducing harsh topicals needed or helping maintain results. Don't expect it to cure melasma alone.

Post-Inflammatory Hyperpigmentation: The More Promising Application

Clinical Application Study - LED Mask Technology, 2020s: Research examining LED photobiomodulation devices specifically for skin rejuvenation has documented pigmentation improvements as a secondary outcome. In studies using LED masks emitting 630nm red and 850nm near-infrared light at 10 mW/cm², participants reported reduction of pigmentation and increased brightening of skin after multiple treatment sessions. Approximately a quarter of participants noticed skin-whitening effects, with some reporting that their skin tone became brighter and blemishes faded. Both participants and evaluators recognized brightening effects, and importantly, hyperpigmentation was not reported as a side effect.

This is particularly interesting: it suggests red light therapy at appropriate wavelengths and intensities not only doesn't worsen pigmentation (a concern some users have) but may actively improve it through consistent use, particularly when inflammation is involved.

What this tells us: For PIH, especially when used early during or right after inflammatory issues, red light appears to have legitimate utility. The anti-inflammatory mechanism seems to genuinely reduce hyperpigmentation that inflammation triggers. The evidence base, while still evolving, consistently points to photobiomodulation's ability to modulate the cellular pathways responsible for excess melanin production following inflammatory events.

Realistic expectations: If you're prone to dark marks after breakouts, consistent red light therapy use might reduce severity and quantity of marks forming. For existing PIH, expect gradual lightening over months, not dramatic fading over weeks. The systematic review findings suggest improvement timelines of 8-12+ weeks with regular use, and the degree of improvement varies based on pigmentation depth, skin type, and treatment consistency.

Sun Damage and Age Spots: The Thinnest Evidence

This is where research is most disappointing. Despite being the most common hyperpigmentation forms, there's remarkably little quality research specifically examining red light therapy's effects on solar lentigines or age-related pigmentation.

What exists is mostly observational: dermatology practices reporting patients using red light therapy for anti-aging also notice improved overall tone and some age spot lightening. But these observations are confounded by patients simultaneously using retinoids, antioxidants, and sunscreen - all improving pigmentation independently of red light.

One small 2017 pilot study examined red light for photoaging and measured melanin density as secondary outcome. They found statistically significant but modest 11% reduction in average melanin density after 12 weeks.

What this tells us: For sun damage and age spots, evidence is mostly theoretical and anecdotal. The same mechanisms helping melasma and PIH should theoretically help sun damage, but we lack robust data confirming meaningful clinical improvement.

Realistic expectations: Don't buy an red light therapy device primarily to fade age spots. If you're using one for other reasons and sun damage improves, consider it bonus. For age spots specifically, you're probably better served by retinoids, vitamin C, and professional treatments.

Research Limitations We Must Acknowledge

Every cited study has significant limitations:

Small sample sizes: Most studies involve 20-60 participants. Enough for preliminary evidence but not definitive conclusions about effectiveness across diverse populations.

Short follow-up: Most studies end at 8-12 weeks with maybe 4-week follow-up. We don't know about long-term maintenance or whether results persist.

Lack of standardization: Different studies use different wavelengths, treatment schedules, and devices. This makes comparing results and drawing broad conclusions difficult.

Publication bias: Negative studies are less likely published. We might be seeing only successful trials while failed experiments languish unpublished.

Homogeneous populations: Most research comes from Asia and predominantly includes lighter skin tones (Fitzpatrick I-III). Very limited data for darker skin.

No head-to-head comparisons: We lack good studies directly comparing red light therapy to other treatments like vitamin C, retinoids, or peels under controlled conditions.

The Bottom Line on Evidence

For melasma: Modest supporting evidence as adjunctive treatment. Not strong enough to use alone, but appears to enhance other treatments' effectiveness.

For post-inflammatory hyperpigmentation: Moderately strong evidence, especially for prevention during active inflammation. Most promising red light therapy application for pigmentation concerns.

For sun damage and age spots: Weak evidence. Theoretical mechanisms are plausible, but clinical data is thin.

Safety profile: Consistently excellent across all studies. Virtually no adverse effects reported beyond occasional mild, temporary redness.

The evidence suggests red light therapy is a legitimate tool, but not a miracle cure and shouldn't be marketed as one. It's best viewed as part of comprehensive approach to hyperpigmentation, not standalone solution.

If you're considering trying it, research supports that decision as reasonable, but adjust expectations accordingly. We're talking about gradual, modest improvement over months, not dramatic transformation over weeks.

Practical Protocol: How to Actually Use Red Light Therapy for Results

The Core Protocol

Frequency: 3-5 Times Per Week

Research consistently shows 3x weekly treatments produce measurable results, while daily treatments don't significantly improve outcomes and may cause unnecessary stress.

Why? Cellular responses to red light take time. Mitochondrial activity boost, inflammatory modulation, and melanin regulation changes happen over hours to days, not minutes. Your cells need recovery time between sessions to complete repair and regeneration processes the light initiated.

More isn't better. Using your device twice daily won't give results twice as fast. It'll just waste time and potentially irritate skin.

Sweet spot: 3-4x weekly for most people. If you've been consistent for 8+ weeks with minimal results, carefully experiment with increasing to 5x weekly. Never go beyond that.

Duration: 10-20 Minutes Per Treatment Area

This depends on your device's power output. Higher irradiance (mW/cm²) means shorter treatment times needed.

Calculate your treatment time:

• Devices with 40-60 mW/cm² at 6 inches: 10-12 minutes per area
• Devices with 25-40 mW/cm² at 6 inches: 15-20 minutes per area
• Devices with less than 25 mW/cm²: Probably not worth your time

Distance: 6-12 Inches from Skin

This is critical and device-specific. Light intensity follows the inverse square law - move twice as far away and you receive one-quarter the intensity.

Most devices are calibrated for optimal use at 6-8 inches. Check your device specifications. Too close doesn't help (no added benefit, just uncomfortable heat). Too far and you're not receiving therapeutic dosing.

Consistency: The Non-Negotiable Element

Missing sessions occasionally won't ruin results, but inconsistency absolutely will. Using your device once one week, four times the next, then not at all for two weeks won't produce results.

Think like going to the gym. Sporadic workouts don't build muscle. Consistent training does. Same principle applies to cellular photobiomodulation.

Schedule it like medication: Same days, same time. Make it non-negotiable, not something you do "when you remember."

The Complete Step-by-Step Protocol

Phase 1: Preparation (5 minutes)

1. Cleanse thoroughly. Non-negotiable. Makeup, sunscreen, and skincare products block light penetration. Start with completely clean, dry skin. If you've been wearing sunscreen or makeup, double cleanse: oil-based cleanser first, then water-based cleanser.
   
   
2. Dry skin completely. Water droplets scatter light and reduce effectiveness.
   
   
3. Remove jewelry. Earrings, necklaces, glasses - anything reflective should be removed.
   
   
4. Gather post-treatment products. Have serums and moisturizer ready to apply immediately after.
   
   
5. Protect eyes. Most quality devices include protective goggles. If yours doesn't, keep eyes closed during facial treatment.
   
   

Phase 2: Treatment (10-20 minutes)

1. Position your device correctly at proper distance (6-8 inches typically). Don't move constantly - keep steady for even exposure.
   
   
2. Treat in sections if needed. Full face panel: 10-20 minutes treats everything simultaneously. Handheld: 3-5 minutes per section (both cheeks, forehead, chin). Focus extra time on areas with most pigmentation.
   
   
3. Relax during treatment. This isn't multitasking time. Put your phone down. Maintain proper positioning.
   
   
4. Note sensations. Mild warmth is normal and good. No sensation is fine too (near-infrared is invisible and generates less heat). Significant heat or discomfort means you're too close.
   
   

Phase 3: Post-Treatment Care (5-10 minutes)

Your skin is primed and receptive after red light therapy. Cellular activity is elevated, microcirculation enhanced, and product absorption significantly improved.

Wait 5-10 minutes before applying products. This allows skin to complete immediate response to light therapy without interference.

Then apply products in this order:

1. Hydrating essence or toner (if you use one)
2. Treatment serums (choose 1-2):
• Vitamin C serum (antioxidant boost, melanin regulation)
• Niacinamide serum (complements melanin regulation)
• Azelaic acid (melanin inhibition, anti-inflammatory)
• Tranexamic acid (increasingly popular for melasma)
3. Restorative serums (optional but beneficial):
• Peptide serums (collagen support)
• Growth factor serums (amplify repair signals)
• Exosome serums (skin communication molecules)
4. Moisturizer
5. Eye cream (if you use one)

On retinoid nights: If you're using prescription tretinoin or OTC retinol:

• Start by using retinoid on alternate nights from red light therapy
• After 2-3 weeks, if skin tolerates well, you can use them the same night
• Sequence: red light therapy → wait 10 minutes → serums → wait 10 minutes → retinoid → moisturizer

Building Your Complete Routine

Morning Routine (every day):

1. Gentle cleanser
2. Vitamin C serum or niacinamide
3. Hyaluronic acid or hydrating serum
4. Moisturizer
5. SPF 50+ SUNSCREEN (Absolutely non-negotiable)

Evening Routine (Red Light Therapy Days - 3-4x per week):

1. Double cleanse
2. Pat skin completely dry
3. RED LIGHT THERAPY SESSION (10-20 minutes)
4. Wait 5-10 minutes
5. Treatment serum
6. Restorative serum (if using)
7. Moisturizer

Evening Routine (Non-Red Light Therapy Days):

1. Double cleanse
2. Chemical exfoliant (AHA/BHA) 1-2x weekly
3. Treatment serums
4. Retinoid (on nights without red light therapy initially, then can combine)
5. Moisturizer

Timing: Morning or Evening?

Evening is generally preferred because:

• Skin already makeup/sunscreen-free from cleansing
• No risk of sun exposure immediately after
• You can use primed, receptive state for treatment serums without rushing
• Easier to maintain consistency as evening wind-down routine

Morning works fine if:

• Evening routine already too long/complex
• You prefer starting your day with self-care
• Your morning schedule is more predictable

A critical factor is consistency, not specific timing. Choose whatever fits your lifestyle and you'll actually do regularly.

Common Mistakes That Kill Results

Mistake #1: Using Red Light Therapy through products Your face must be completely clean and dry. Sunscreen, makeup, even moisturizer - all block light penetration. You're essentially shining red light on a barrier.

Mistake #2: Giving up too soon You won't see dramatic results in two weeks. Probably not in four weeks. Minimum commitment: 8 weeks of consistent (3-4x weekly) use before evaluating. Optimal evaluation: 12-16 weeks.

Mistake #3: Inconsistent use Five times one week and once the next two weeks averages to "regular use" in your mind, but your cells don't experience it that way. Cellular changes require consistent signaling.

Mistake #4: Wrong distance Holding your device 18 inches away means you're receiving a fraction of therapeutic dose. Too close and you're uncomfortable but not more effective. Follow device-specific guidelines precisely.

Mistake #5: Skipping sunscreen This is self-sabotage. UV exposure triggers melanin production faster than any treatment can fade it. If you're not wearing SPF 50+ daily, reapplied every 2 hours in sun, you're taking one step forward and two steps back.

Every. Single. Day. No exceptions. Even cloudy days. Even winter. Even "just inside." UVA penetrates windows.

Mistake #6: Using a low-quality device If your device doesn't specify exact wavelengths and irradiance output, it's probably not delivering therapeutic doses. This is why some people use devices religiously with zero results.

Tracking Progress

• Weekly photos in consistent lighting
• Same angle, same time of day
• Natural light near window is best
• Don't expect dramatic changes week to week
• Review monthly for realistic assessment

Remember: Red light therapy is a marathon, not a sprint. The people who see results are those who commit to the protocol, maintain consistency, and give it adequate time to work its cellular magic.

The question isn't whether red light therapy can work - research suggests it can for many people. The question is whether you'll use it correctly and consistently enough to find out.

FAQ

Does red light therapy help with hyperpigmentation?

Yes, clinical studies show red light therapy can help reduce hyperpigmentation when used consistently at specific wavelengths (630nm red and 850nm near-infrared). Research demonstrates it's most effective for post-inflammatory hyperpigmentation and melasma, especially when combined with standard treatments like topical serums and sun protection. Expect gradual improvement over 8-16 weeks with 3-4 sessions weekly, not overnight results.

Does red light therapy cause hyperpigmentation?

No, red light therapy does not cause hyperpigmentation when therapeutic wavelengths (630-850nm) are used correctly. Unlike UV light or certain lasers, red and near-infrared light downregulate melanin production rather than stimulate it. Clinical studies consistently report no hyperpigmentation as a side effect.

Does red light therapy make hyperpigmentation worse?

Red light therapy does not typically worsen hyperpigmentation and is safe across all skin tones, unlike certain lasers that risk rebound darkening. However, using incorrect wavelengths, skipping daily SPF 50+ sunscreen, or device misuse may prevent improvement. If darkening occurs, discontinue use and consult a dermatologist, though adverse reactions are extremely rare.
