Can an LED face mask improve wrinkles?

Small human trials offer some encouragement, but they do not prove that every mask works—or that changes last.

Some LED face masks may make certain wrinkles less noticeable, but results are mixed. In one trial, photos showed changes in the length of some wrinkles, while specialists’ overall wrinkle ratings did not differ between groups. Another trial found improvements in crow’s-feet with a different mask. Neither study proves that every product works, or that any effect will last. (pubmed.ncbi.nlm.nih.gov)

What happened

In a 2025 study, researchers assigned 95 women aged 45 to 60 to receive a red-light mask treatment twice or three times a week for four weeks, or a comparison treatment without the active light. Sessions lasted 21 minutes. Participants and the people assessing their photos did not know which group was which. (pubmed.ncbi.nlm.nih.gov)

Computer measurements of photos showed shorter wrinkles between the eyebrows and beside the right eye in the active-treatment groups than in the comparison group. But specialists’ overall wrinkle ratings did not differ significantly between groups. The women receiving active treatment also reported greater satisfaction with their appearance.

A separate 2025 trial tested a home-use mask combining red light with near-infrared light, which is invisible to the eye. Sixty people of Asian descent, aged 30 to 65, enrolled, and 59 were included in the results analysis. They used the mask for 12 weeks, with a follow-up assessment at week 16. Assessors reported greater improvement in crow’s-feet in the active-treatment group. (pubmed.ncbi.nlm.nih.gov)

Why it matters

Both studies tested people, not just skin cells in a dish. They also used comparison treatments, making them more useful than before-and-after photos alone. Still, an improvement in a measurement does not tell every shopper how noticeable the change will be in a mirror.

What we don't know

The trials used different devices and schedules. Their results cannot establish that a different mask, light setting or treatment routine will work as well. The studies also do not establish how long improvements last after treatment stops, or how well the results apply to everyone.

These wrinkle studies do not prove that a mask will improve redness or blemishes. Those claims need their own evidence.

What this means for you

Treat a mask as an optional cosmetic purchase, not a guaranteed fix. Before buying, ask whether the specific device has been tested in people for the concern you want to address. Check the instructions, including eye-protection advice, and consider whether you can comfortably follow its routine.

If you have an eye condition, a light-sensitive skin condition or take medicines that make you sensitive to light, ask a clinician before use. Stop and seek advice if the device causes discomfort. A mask is not a substitute for sun protection or care for a persistent skin problem.

Sources and conflicts

This story draws on two published human trials. The authors of the 95-person study declared no competing interests; its PubMed record lists research grants. The authors of the second trial declared no conflicts of interest and stated that study planning, analysis and writing were independent of funding sources. These disclosures are author statements and should still be independently checked where practical. (pubmed.ncbi.nlm.nih.gov)
