Does red light therapy work for wrinkles? Red light therapy for wrinkles produces small, measurable improvements in short trials. In a 16-week sham-controlled trial of 60 adults, a home mask improved crow's-feet grades more than a sham device. In a 95-woman trial, though, blinded experts saw no difference. No controlled trial we found checked results more than 30 days after treatment ended.
Evidence: Moderate (modest, short-term changes).
Key takeaways
- A 2026 systematic review of 8 at-home LED studies (365 participants) found significant improvements in wrinkles, texture, elasticity and eye-area lines, with side effects that were "infrequent, mild, and transient" (Das et al., 2026).
- In a double-blind, sham-controlled trial of 60 adults, a 630 nm + 850 nm home mask improved crow's-feet scores more than sham at 8, 12 and 16 weeks (Park et al., 2025).
- In a sham-controlled trial of 95 women, blinded specialists found no difference on a wrinkle scale. Software measurements did find shorter frown lines and eye wrinkles (Bragato et al., 2025).
- The same 95-woman trial found that 3 sessions a week were no better than 2 (Bragato et al., 2025).
- Red light did not improve skin elasticity or hydration in a 137-woman split-face trial, even though wrinkle volume fell 31.6% (Mota et al., 2023).
Does red light therapy work for wrinkles?
Yes, modestly and in the short term. Sham-controlled trials show measurable wrinkle changes over 4 to 16 weeks, but the size of the effect depends on who or what does the measuring.
The strongest single test is Park and colleagues' 2025 multicenter, randomized, double-blind trial. It enrolled 60 adults of Asian descent aged 30–65, with Fitzpatrick skin types II–V and moderate crow's feet (Park et al., 2025). Half used a home mask combining 630 nm red LEDs and 850 nm infrared diodes for 16 weeks, and half used a sham device. Independent raters and investigators both found significant differences from sham at 8, 12 and 16 weeks. In the full analysis set, independent raters reported an improvement rate of 86.2%, a 69.5% difference from the sham group. The authors reported no conflicts of interest, and the abstract doesn't state the funder.
The 2026 Das review pooled 8 at-home LED studies with 365 participants, using wavelengths from 440 to 1072 nm, mostly red and near-infrared (Das et al., 2026). The studies reported significant improvements in wrinkles and other signs of aging. The review's authors also flagged varied treatment protocols, limited comparative data and "underrepresentation of diverse skin phenotypes." Evidence: Moderate.
What is red light therapy, and how is it supposed to smooth wrinkles?
Red light therapy, also called photobiomodulation (PBM), shines low-energy red or near-infrared light on the skin to change how cells behave. The proposed mechanism is cellular; it has not been shown directly in human wrinkles.
A 2024 dermatology CME review defines the red range as 620–700 nm and near-infrared as 700–1440 nm, usually delivered by low-level lasers or LEDs (Mineroff et al., 2024). Body uses are a separate question; see red light therapy for cellulite. A 2021 review describes the theory: absorbed light boosts mitochondrial ATP (the cell's energy molecule), cell signaling and growth-factor production, and reduces oxidative stress (Glass, 2021). In a 2026 review of energy-based devices, photobiomodulation and photodynamic therapy appear as separate device categories (Kelm & Murphrey, 2026).
Some tissue findings fit the theory. A controlled trial found higher collagen density on ultrasound after 30 sessions (Wunsch & Matuschka, 2014). Electron microscopy of biopsies from 5 subjects showed thicker collagen fibers after treatment (Goldberg et al., 2006). Kelm and Murphrey's review of 23 articles, 11 of them on light-based devices, found a positive effect on cellular senescence (aged cells that stop dividing). The authors also called that literature "scarce." Evidence: Limited (mechanism and tissue markers, not proof of visible change).
What did the best red light therapy for wrinkles trials find?
The trials with a control group show small but real changes. The older studies without a control group report bigger gains, but they can't separate the light's effect from placebo or natural variation.
Three designs matter here. A sham-controlled trial gives one group a device that looks real but emits no therapeutic light, so it is the fairest test. A split-face trial treats each side of the face differently in the same person. An uncontrolled study treats everyone and compares them with their own baseline.

Older Omnilux studies (n=31, 36 and 13) had no control group described in their abstracts and are covered in the text.
The early studies of a 633/830 nm clinic system had no control group in their abstracts. In 31 subjects given 9 treatments, 52% improved their photoaging scores by 25%–50% by week 12 (Russell et al., 2005). In 36 subjects treated over 5 weeks, profilometry (a surface-texture measurement) showed a significant wrinkle improvement (Goldberg et al., 2006). In 13 subjects, investigators rated most responses as "moderate" or "slight" (Baez & Reilly, 2007). Evidence: Moderate for controlled trials; Early / preliminary for uncontrolled studies.

What do red light therapy face before-and-after results look like in studies?
In the trials, "before and after" means measurements, not dramatic photos. Typical outcomes were statistically significant, sham-beating changes on a crow's-feet grading scale (Park et al., 2025), roughly 30% less wrinkle volume around the eyes on 3D imaging (Mota et al., 2023), and shorter lines measured in software (Bragato et al., 2025). A recurring reader question online is whether they would notice anything in the mirror at all. The Bragato result suggests that is a fair worry.
Why do marketing claims overstate red light results?
Because the result depends on how wrinkles are measured, and because much of the evidence is small or industry-linked. A software-measured change doesn't always show up when experts look at photos.
In the Bragato trial, 3 blinded specialists scored photos on the Wrinkle Assessment Scale and found no significant differences between groups (Bragato et al., 2025). A blinded researcher using ImageJ software did find shorter glabellar (between-the-brows) and right periorbital wrinkles in the treated groups (p < 0.001). Both results come from the same 95 women.
Reviews flag broader problems. Glass's 2021 review cites "methodologic flaws, small patient cohorts, and industry funding" (Glass, 2021). A 2025 systematic review of 19 regenerative-aesthetics studies, including photobiomodulation, found a "significant lack of consistent, high-quality evidence" (Rahman et al., 2025). One 20-woman mask study reported progressive results over 3 months, but its authors include the CEO of the company that makes the mask and a consultant to that company (Couturaud et al., 2023). Evidence: Mixed / contested (expert vs instrument ratings).
How long does red light therapy for wrinkles take, and how often should you use it?
Trials measured changes after 4 weeks at the earliest, and 2 sessions a week performed as well as 3 in the one trial that compared frequencies. Any faster timeline, or a daily schedule, is a device-maker or clinic convention, not trial data.
In the Bragato trial, women used a 21-minute red LED mask 3 times a week (12 sessions) or twice a week (8 sessions) for 4 weeks (Bragato et al., 2025). The number of sessions didn't change satisfaction or photo results, and the authors concluded that 2 weekly sessions "seem to be sufficient." Other studies used 3 sessions a week (Yi et al., 2025) or 5 sessions a week (Kim et al., 2026), so no single best schedule exists. Evidence: Limited.
When trials measured wrinkle changes
- 4 weeks8–12 sessions
Software-measured wrinkle changes (Bragato 2025); about 30% less eye-area wrinkle volume after 10 sessions (Mota 2023)
- 5 weeks9 treatments
Course length in early uncontrolled studies, assessed up to week 12 (Goldberg 2006; Baez 2007)
- 6 weeksMen's mask study
Participants perceived the biggest gain in fine lines and wrinkles (Mineroff 2023)
- 8 weeks
- 12–16 weeks
- After stoppingUp to about 1 month
Benefits on photos 30 days after treatment (Bragato 2025); results up to 1 month after stopping in a company-linked study (Couturaud 2023)
Is red, near-infrared, amber or yellow light better for anti-wrinkle LED light therapy?
No color has clearly won. Red and amber performed about the same, and broadband light did no better than red alone.
| Comparison | Study | Result |
|---|---|---|
| Red (660 nm) vs amber (590 nm) | Split-face RCT, n=137, 4 weeks (Mota 2023) | Wrinkle volume down 31.6% vs 29.9% |
| Broadband (570–850 nm) vs red only (611–650 nm) | Controlled trial, n=136, 30 sessions (Wunsch 2014) | Broadband "showed no advantage" |
| 570 nm vs 590 nm yellow, each + red + infrared | RCT, n=30, 8 weeks (Yi 2025) | Both improved; 570 nm better on wrinkles |
| Broader-spectrum near-infrared mask | Uncontrolled, n=20, 12 weeks (Kim 2026) | Wrinkles down "by up to 27.22%" |
Many masks pair red with near-infrared, including the device in the Park sham-controlled trial (630 + 850 nm). A men's mask using 633, 830 and 1072 nm produced self-reported and photographic improvements over 6 weeks, but the abstract doesn't report the number of participants and the study had no control group (Mineroff et al., 2023). Evidence: Limited.
Do at-home red light masks for wrinkles work as well as in-office LED?
No study we found has compared them directly. Home masks have their own trial evidence, but it is unclear whether LEDs match the laser-based systems used in many of the better studies.
| Feature | At-home LED masks | In-office LED or laser |
|---|---|---|
| Pooled evidence | 8 studies, 365 participants (Das 2026) | Excluded from that review; no pooled wrinkle data in our sources |
| Best controlled trial | Sham-controlled, n=60, 16 weeks (Park 2025) | Early clinic LED studies had no control group described |
| Light source question | LED | Most higher-quality studies used lasers; LED equivalence unclear (Glass 2021) |
| Head-to-head trial | None found | None found |
Bottom line: Home masks have reasonable short-term data. Whether a clinic session is better has not been tested.
A 2024 review notes that dermatologists should counsel patients on proper use of home devices "to best manage safety and expectations" (Mineroff et al., 2024). Readers often say the real barrier is consistency: a mask that is uncomfortable or slow to use ends up in a drawer, and the trials only show results for people who kept using it. Evidence: Moderate for at-home benefit; no data for the comparison.
Can red light therapy tighten skin or help neck wrinkles?
The tightening evidence is mixed, and no study we reviewed tested red light on neck wrinkles. Wrinkle depth and firmness are different outcomes, and red light has better data for the first.
In the 137-woman split-face trial, neither red nor amber light improved viscoelasticity (how skin stretches and springs back) or hydration (Mota et al., 2023). A 20-person near-infrared study without a control group reported better elasticity and density after 12 weeks (Kim et al., 2026). A device-engineering paper reported better elasticity, sagging and wrinkles with a micro-LED mask than with a conventional mask, but the abstract doesn't give the number of participants (Kim et al., 2024).
For the jawline, one 4-week study measured prejowl and lower-chin changes. Both groups improved, including the group using only a hyaluronic acid ampoule (Kim et al., 2020). For neck creases, see our guide to neck lines and, if the change followed weight loss, ozempic neck. For topical options, compare peptides for skin tightening. Red light is sold for body skin too; for dimpled thighs, see our read of red light therapy for cellulite. Evidence: Mixed / contested (tightening); no data (neck).
Can you combine red light therapy for wrinkles with skincare?
One study suggests a red light mask can add to a topical product, but no study tested LED with peptides or retinoids. Red light is best treated as an add-on to a routine, not a replacement.
Kim and colleagues gave 48 people a hyaluronic acid (HA) ampoule for 4 weeks, with or without a 660/850 nm home LED mask (Kim et al., 2020). Both groups improved on measures including nasolabial fold and prejowl volume. The LED + HA group showed a "significantly faster and higher rate of improvement." The abstract doesn't report the funder.
We found no trial combining LED with copper peptides, other peptide ingredients or tretinoin, so we can't tell you whether those pairings help or irritate. For where a device fits around your products, see our skincare routine order guide. Evidence: Early / preliminary.
Is red light therapy safe for your face?
Short-term studies report few and mild side effects, but long-term safety data don't exist. People with skin of color are underrepresented in the trials.
The 2026 Das review found that adverse events were "infrequent, mild, and transient" (Das et al., 2026). A 2023 focused systematic review found no clinical trial data linking photobiomodulation to significant adverse events, including new or recurrent cancer, and reported that it "does not induce dysplastic change in healthy cells" (Glass, 2023). The Rahman review found that an absence of long-term safety data was common across regenerative aesthetics studies (Rahman et al., 2025).
The Mineroff review notes that light can have varied effects across skin types and advises dermatologists to counsel patients with skin of color specifically (Mineroff et al., 2024). Some readers worry about pigment or melasma getting worse. None of the trials in our review measured that, so we can't say how often it happens. Follow the device's instructions, and ask a clinician before use if you have an eye condition or take a light-sensitizing medicine. There are no data here on pregnancy or breastfeeding, so ask a clinician. Evidence: Limited.
How does red light compare with other wrinkle treatments?
We don't know, because no trial in our review compared red light head-to-head with retinoids, lasers or injectables. Red light is better described as an add-on than a substitute.
A 2025 meta-analysis of 6 studies (497 patients) compared lasers with other rejuvenation methods, including radiofrequency and intense pulsed light, and mentions no LED arm in its abstract (Sodagar et al., 2025). The Mineroff review describes photobiomodulation as an option "as an alternative or adjuvant" to other treatments, without trial comparisons (Mineroff et al., 2024). For a topical with its own wrinkle trials, see whether tretinoin helps with wrinkles and peptides vs retinol. Evidence: no head-to-head data.
Where the evidence stops
- Durability. The controlled data stop 30 days after treatment (Bragato 2025). Whether maintenance sessions are needed is untested.
- Measurement. Expert ratings and software can disagree in the same trial.
- Dose. Wavelengths, energy and session lengths vary widely, and no optimal dose is established (Das 2026).
- Home vs clinic. No head-to-head trial, and LED vs laser equivalence is unclear (Glass 2021).
- Neck and tightening. No neck trial, and conflicting elasticity results.
- Skin of color and men. Only 2 controlled trials reported phototypes (II–V and II–IV), and the one men's study doesn't report its size in the abstract.
FAQ
How long does red light therapy take to work on wrinkles?
In trials, measured wrinkle changes appeared after 4 weeks of 8 to 12 sessions. In a 16-week sham-controlled mask trial, the first significant difference from sham came at 8 weeks. A timeline faster than 4 weeks is a device-maker or clinic claim, not trial data.
How often should I use a red light mask for wrinkles?
In a sham-controlled trial of 95 women, 3 sessions a week did no better than 2 on satisfaction or photo measures, and the authors concluded that 2 weekly sessions seem to be sufficient. Other studies used anywhere from 2 to 5 sessions a week, so no best schedule has been established. Follow your device's instructions.
Do at-home LED masks work as well as in-office treatment?
No study we found compared them directly. A 2026 systematic review of 8 at-home LED studies with 365 participants found improvements in wrinkles, texture and elasticity. A 2021 review said it is unclear whether LEDs match the laser-based systems used in most of the higher-quality studies.
Does red light therapy tighten skin?
The evidence is mixed. A split-face trial of 137 women found no improvement in skin viscoelasticity or hydration after 4 weeks. Smaller studies without a sham group reported better elasticity, but they cannot rule out placebo effects.
Do red light therapy results last after you stop?
Durability is barely studied. A sham-controlled trial still found benefits on photos taken 30 days after treatment, and a 20-woman study with company-linked authors reported results lasting up to 1 month after stopping. Whether you need ongoing sessions to keep results has not been tested.
Is red light therapy safe for your face?
In a 2026 review of at-home LED studies, side effects were infrequent, mild and transient, and a 2023 review found no clinical trial data linking it to significant adverse events, including cancer. Long-term safety data are lacking, and dermatologists are advised to counsel patients with skin of color specifically. If you have an eye condition or take a light-sensitizing medicine, ask a clinician before using a device.
Is red light better than amber, yellow or near-infrared light for wrinkles?
Not clearly. In a split-face trial, red light cut periocular wrinkle volume by 31.6% and amber light by 29.9%, and a broadband light trial found no advantage over red light alone. Many masks combine red with near-infrared, including the device in the best sham-controlled trial.
Does red light therapy work on neck wrinkles?
No study we reviewed tested red light on neck wrinkles, so we can't say. The trials measured the face, mostly around the eyes and between the brows.
