Do at-home LED light masks work for wrinkles? What the trials show

By Juvenate Editorial Published October 24, 2026 Last updated October 24, 2026

Scroll through any social feed and you will see glowing red face masks promising smoother, firmer skin in a few minutes a day. They look futuristic, they feel low-effort, and some cost hundreds of dollars. So do they actually work? The honest answer is "a little, maybe, for some people, and we are still learning." Here is what the research shows and how to think about it before you buy.

This is not medical advice. Talk with a board-certified dermatologist about your skin and about any device before you use it. We are not recommending or linking to any product. No affiliate links. Disclosure.

What these masks are

Most at-home masks use light-emitting diodes (LEDs) in red, and sometimes near-infrared, wavelengths. The American Academy of Dermatology (AAD) explains that this approach is called photobiomodulation, that dermatologists sometimes offer it in the office for concerns such as acne and wrinkles, and that the red light dermatologists use is more powerful than the light in devices sold for home use. Most home devices use LEDs, which the AAD considers safe for home use.

In a dermatologist’s office, red light is usually a complement, not a stand-alone fix. The AAD says it is typically added to a treatment plan that already includes standard therapies such as a medicated cream, microneedling or a chemical peel.

What the research shows

A modest, mixed evidence base

A 2018 systematic review of 31 randomized controlled trials of LEDs in dermatology rated the evidence by condition. Acne, herpes simplex and zoster, and acute wound healing earned a grade B recommendation. Other skin conditions received a grade C or D, which means weaker evidence. The authors noted that some studies had small samples (fewer than 20 people), no blinding, no sham (placebo) device, and widely varying treatment settings.

That last point is the heart of the problem. Masks differ in wavelength, brightness, session length and how often you are meant to use them, and studies test different combinations. The AAD says plainly that researchers study different devices, for different amounts of time, to answer different questions, so results cannot be directly compared.

A recent sham-controlled trial

One of the better recent studies tested a home-use mask against a look-alike sham device. In this 2025 trial, 60 adults aged 30 to 65 (all of Asian descent, with skin types II to V) used either a mask combining 630 nm red LED light with 850 nm near-infrared light, or a sham device that was dimmer and lacked the infrared light. Both groups used their device for 9 minutes, 5 times a week, for 12 weeks. Trained independent raters scored the lines around the eyes (crow’s feet).

By the raters’ assessment, 25 of 29 people in the mask group (86.2%) showed improvement, versus 5 of 30 (16.7%) in the sham group. The score differences were statistically significant at 8, 12 and 16 weeks.

That is encouraging, and it is a stronger design than many earlier studies. But keep it in perspective:

It was small (60 people) and followed participants for a short time.
It studied one area, the corners of the eyes, and one specific device.
The study was funded by the device maker’s company, although the authors state that the design, data analysis and writing were independent of the funder.
It tells us about that mask, not masks in general.

What the AAD says

The AAD says some studies indicate that red-light LED devices can produce “subtle to noticeable” results on the face for fine lines and wrinkles, dark spots, rough-feeling skin and redness. It then adds a note of caution: “While FDA clearance and the research results are encouraging, it’s difficult to know how effective at-home devices are.” It lists open questions, including how long red light can be used safely, how many treatments are best for concerns like crow’s feet, and what amount of light is best at home.

”FDA cleared” is not the same as “it works”

You will see “FDA cleared” on many boxes. The AAD explains that this means the FDA considers the device to pose a low risk to the public. It does not tell you how effective the device is. And “FDA approved” or “FDA certified” have no meaning for a medical device, because the FDA clears devices; it does not approve or certify them. If a brand uses those phrases, treat that as a flag to read the claims more carefully.

Who should check with a dermatologist first

The AAD recommends seeing a board-certified dermatologist before using red light at home, and it highlights a few situations:

Darker skin tones. The AAD says research shows people with darker skin are more sensitive to visible light, including red light, and this can lead to hyperpigmentation (dark spots) that may be more intense and longer-lasting than spots caused by sunlight.
Light-sensitive conditions. A condition such as lupus can worsen with red light exposure.
Medicines that increase light sensitivity. Red light may not be recommended if you take one.
Uncertainty about whether it will help. The AAD notes that devices often cost between $100 and more than $1,000, so it can be worth knowing before you buy.

Practical safety steps from the AAD

If you and your dermatologist decide to try a mask, the AAD suggests:

Choose a device made for the concern you want to treat, such as wrinkles.
Choose one that is FDA cleared.
Follow the directions that come with it, exactly.
Wear eye protection if the directions say to, using the protection they recommend. The AAD specifically says not to substitute sunglasses for protective goggles.

In the short term, the AAD says red light appears safe, with mild side effects such as temporary pain or irritated skin. It also says we do not yet know the long-term effects.

What to expect, realistically

It is not a one-and-done. The AAD says you need to use red light regularly, that it takes time to see results, and that not everyone sees them.
It will not replace the basics. Daily sunscreen and, for some people, a prescription retinoid have far more evidence behind them for wrinkles. We cover sun protection in our post on sunscreen and anti-aging.
It will not lift or tighten significantly. Please do not expect a mask to change deeper laxity.

The bottom line

LED masks are not snake oil, and they are not miracle devices either. There is some encouraging evidence for modest improvement in fine lines, particularly from carefully designed trials, but the studies are short, small and varied, and the AAD says it is difficult to know how effective at-home devices are. If you are tempted to try one, talk to a dermatologist first, especially if you have darker skin or take a medicine that makes you sun-sensitive, and put daily sunscreen first.
