Key takeaways:
- LED face masks are wearable devices that use specific wavelengths of light to stimulate cellular processes and address various skin concerns, including acne, signs of aging, and hyperpigmentation.
- The two main types of light used in LED masks are blue light, which may target and kill acne-causing bacteria, and red light, which may stimulate collagen production and reduce signs of aging.
- While the overall efficacy of LED face masks is still being understood, dermatologists agree that they can generally be used as part of a comprehensive skincare regimen that includes cleansing, moisturizing, and sun protection.
- Before using an LED face mask, check with your dermatologist to determine whether it’s appropriate for your skin.
Have you noticed an uptick in influencers, dermatologists, and people you know touting the benefits of LED face masks? If you’re on the fence about whether to buy this at-home skincare tech, here’s what you need to know to help make an informed decision.
How do LED face masks work?
LED face masks use low level light therapy (LLLT), a non-invasive treatment that’s designed to leverage the body's natural response to light to achieve cosmetic and therapeutic benefits. Here’s how it works:
- The facemask emits specific wavelengths of light that penetrate the skin to varying depths.
- Photoreceptors in the skin absorb the light and convert it into biochemical signals.
- These biochemical signals initiate a cascade of cellular activity, including the release of various molecules.
- These molecules trigger processes that promote skin rejuvenation and healing.
Manufacturers of LED face masks recommend varying levels of treatment duration and consistency of use for best results. In general, you can expect to use your LED facemask roughly 3-5 times a week for 10-30 minutes per session.
Should I moisturize before using an LED mask?
No. It’s recommended that you gently cleanse your face before using an LED face mask, and apply moisturizer and other skincare products only after you’re finished using the mask.
Types of light popular in LED face masks
LED face masks use different types of light with varying wavelengths to target skin concerns. The most commonly used types of light include red light, near-infrared light, and blue light. While there is some evidence showing that at-home low-level light therapy improves skin health, scientists agree that more studies are needed.
Red Light Therapy (RLT) and Near-Infrared (NIR) Light
Red light therapy is commonly used in LED face masks and is popular for its supposed anti-aging effects. It penetrates the skin and has been found to stimulate collagen production and improve circulation, which may lead to reduced wrinkles and fine lines, improved skin tone, and a more youthful appearance.
Near-infrared light, which has longer wavelengths and penetrates deeper into the skin and tissues compared to red light, is commonly used in LED face masks. It has also been utilized to aid in muscle recovery and wound healing.
The jury’s out on whether red light therapy definitely works or not. An erratum to a 2021 review paper on low-level light therapy states that “a reasonable body of clinical trial evidence exists to support the role of low-energy red/near-infrared light as a safe and effective method of skin rejuvenation… However, its ubiquity and commercial success have outpaced empirical approaches on which solid clinical evidence is established.”
In other words, while smaller studies and anecdotal evidence suggest that regular application of red light therapy can reduce signs of aging over time, larger, high-quality studies are needed to truly determine its efficacy.
Blue Light Therapy (BLT)
Another popular light found in LED face masks, blue light is commonly used to treat acne. It works by penetrating the skin and targeting acne-causing bacteria, which helps reduce inflammation and mitigate the severity of future breakouts.
Several reviews and meta-analyses of the literature, including this 2021 Sensors review, have found that accurately and consistently applied blue light phototherapy may help improve acne symptoms, although more research is needed for this to be conclusive.
Do dermatologists recommend LED masks?
Dermatologists are generally comfortable recommending LED face masks as a non-invasive, supplementary skincare treatment, but with some caveats. LED face masks are not considered as effective as in-office laser treatments and should not be expected to have the same effects.
It's essential to consult with your dermatologist to determine if LED face masks are suitable for your skin, particularly if you have sensitive skin or a specific skin condition or concern. Your dermatologist may not recommend LED face masks if your skin barrier is not intact or if you have experienced photosensitivity in the past. Only minimal research has been conducted on how LED face masks affect darker skin tones. If you have a darker complexion, you may want to work with your dermatologist to find a melanin-friendly mask.
For the best results, LED face masks should be used as part of a comprehensive skincare routine that involves sun protection and moisturizing. If you’re planning to use an LED face mask, we recommend removing your makeup with Gladskin makeup remover and cleansing your face with our minimally formulated cleanser before using the mask, then applying a gentle moisturizer after you use your mask.
Make sure you’re following the instructions of your individual face mask in terms of treatment duration, treatment regularity, cleaning procedures, wearing protective eyewear, etc.
When it comes to LED face masks, individual results may vary. You won’t know if LED face masks work for you until you try them.
Are there any risks associated with using an LED mask?
One of the biggest known risks of LED face masks is eye safety. Long-term exposure to red and blue light may lead to eye health complications, and while most masks have eye cut-outs, some light may spill over. Wearing the mask for longer than the recommended duration increases these risks. Some masks come with protective eyewear. This should be worn as directed.
Other risks include skin sensitivity (some users may experience mild irritation, redness, or dryness, particularly with prolonged or frequent use) and the potential for increased photosensitivity. The latter occurs because LED therapy may increase skin sensitivity to sunlight in some individuals, necessitating sunscreen use or sometimes avoiding sun exposure post-treatment.
Is it worth buying an LED mask?
If they’re within your budget and appropriate for your skin, LED face masks can be a helpful addition to your skincare routine. Here are some additional pros and cons to consider:
Advantages of LED face masks:
- Non-Invasive: LED face masks offer a non-invasive treatment option for various skin concerns.
- Convenient: Can be used at home without the need for frequent visits to a dermatologist.
- No Downtime: Unlike some in-office cosmetic procedures, LED therapy typically requires no downtime, allowing users without photosensitivity to resume normal activities immediately.
Disadvantages of LED face masks:
- Eye Safety Concerns: LED lights can be intense, requiring eye protection to avoid potential damage.
- Increased Sensitivity: For some people, prolonged or frequent exposure to LED therapy can lead to mild skin irritation and/or photosensitivity.
- Cost: Initial investment in a quality LED face mask can be expensive, depending on the brand and the type of mask you purchase (LED face mask, LED eye patch, LED “bibs” for the neck and décolleté, etc.)
