Beyond the Hype: Should You Buy an LED Face Mask?

Key Points:

● LED facial 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 can target and kill acne-causing bacteria, and red light, which can stimulate collagen production and reduce signs of aging.

● While the overall efficacy of LED face masks is still being studied, dermatologists agree that they can generally be used as part of a comprehensive skin care regimen that includes cleansing, moisturizing, and sun protection.

● Before using an LED facial mask, consult your dermatologist to determine if it is suitable for your skin.

Have you noticed an increase in influencers, dermatologists, and people you know touting the benefits of LED face masks? If you're on the fence about buying this at-home skincare technology, here's what you need to know to make an informed decision.

How do LED face masks work?

LED facial masks use low-level light therapy (LLLT), a noninvasive treatment designed to harness the body's natural response to light to achieve cosmetic and therapeutic benefits. Here's how it works:

1. The facial mask emits specific wavelengths of light that penetrate the skin to different depths.

2. Photoreceptors in the skin absorb light and convert it into biochemical signals.

3. These biochemical signals initiate a cascade of cellular activities, including the release of various molecules.

4. These molecules activate processes that promote skin rejuvenation and healing.

Manufacturers of LED facial masks recommend varying levels of treatment duration and consistency of use for best results. In general,  You can expect to use your LED facial mask about 3-5 times per week for 10-30 minutes per session .

Should I moisturize before using an LED mask?

No. It is recommended that you gently cleanse your face before using an LED face mask, and apply moisturizer and other skincare products only after you have finished using the mask.

Types of light popular in LED face masks

LED face masks use different types of light with different wavelengths to address skin problems. The most commonly used types of light are red light, near-infrared light, and blue light. Although  While there is some evidence that low-level light therapy used at home improves skin health, scientists agree that more studies are needed.

Red light therapy (RLT) and near-infrared (NIR) light

Red light therapy is often used in LED facial masks and is popular for its supposed anti-aging effects. It penetrates the skin and has been shown to stimulate collagen production and improve circulation, which  can lead to fewer 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 often used in LED masks. It has also been used to promote muscle recovery and wound healing.

It is not yet clear whether red light therapy is definitively effective or not. An erratum on a  A 2021 review article on low-level light therapy states that "a reasonable amount of clinical trial evidence exists to support the role of low-energy red/near-infrared light as a safe and effective method for skin rejuvenation… However, its ubiquity and commercial success have outpaced empirical approaches on which robust clinical evidence is based."

In other words, while smaller studies and anecdotal evidence suggest that regular application of red light therapy may reduce signs of aging over time, larger, high-quality studies are needed to truly establish its efficacy.

Blue light therapy (BLT)

Blue light, also popular in LED face masks, is often used to treat acne. It works by penetrating the skin and attacking acne-causing bacteria, reducing inflammation and lessening the severity of future outbreaks.

Several reviews and meta-analyses of the literature, including this one  2021 Sensors review , found that precisely and consistently applied blue light therapy can help improve acne symptoms, although more research is needed to definitively confirm this.

Do dermatologists recommend LED masks?

Dermatologists are generally willing to recommend LED facial masks as a non-invasive, complementary skincare treatment, but with some caveats. LED facial masks are not considered as effective as in-clinic laser treatments and should not be expected to have the same effects.

It's essential to consult your dermatologist to determine if LED face masks are suitable for your skin, especially if you have sensitive skin or a specific skin condition or concern. Your dermatologist may advise against LED face masks if your skin barrier is compromised or if you have a history of photosensitivity. Minimal research has been conducted on how LED face masks affect darker skin tones. If you have darker skin, you can work with your dermatologist to find a melanin-friendly mask.

For best results, LED face masks should be used as part of a comprehensive skincare routine that includes sun protection and hydration. If you plan 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, and then a mild moisturizer after using the mask.

Be sure to follow the instructions for your individual face mask regarding treatment duration, frequency of use, cleaning procedures, wearing of protective eyewear, etc.

When it comes to LED face masks, results can vary from person to person. 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. Prolonged exposure to red and blue light  Can lead to eye health problems, and although most masks have eye openings, some light can still pass through. Wearing the mask longer than the recommended time increases these risks. Some masks come with eye protection, which should be worn according to the instructions.

Other risks include skin sensitivity (some users may experience mild irritation, redness, or dryness, especially with prolonged or frequent use) and the possibility of increased photosensitivity. This is because LED therapy can increase the skin's sensitivity to sunlight in some people, requiring the use of sunscreen and avoiding sun exposure after treatment.

Is it worth buying an LED mask?

If they're within your budget and suitable for your skin, LED face masks can be a useful addition to your skincare routine. Here are some additional pros and cons to consider:

Benefits of LED Face Masks:

1. Non-invasive: LED facial masks offer a non-invasive treatment option for a variety of skin concerns.

2. Convenient: Can be used at home without frequent visits to a dermatologist.

3. No Downtime: Unlike some in-clinic cosmetic procedures, LED therapy typically requires no downtime, allowing users without photosensitivity to immediately resume their normal activities.

Disadvantages of LED Face Masks:

1. Eye Safety Hazards: LED lights can be bright, requiring eye protection to prevent potential harm.

2. Increased sensitivity: For some people, prolonged or frequent exposure to LED therapy may lead to mild skin irritation and/or photosensitivity.

3. Cost: The initial investment in a good quality LED face mask can be expensive depending on the brand and type of mask you buy (LED face mask, LED eye patch, LED neck and décolletage bibs, etc.).
