Do light therapy masks really work?

LED light therapy masks have taken social media by storm. Celebrities and influencers alike have shared selfies and videos showcasing the use of these masks to enhance skin quality. While the visual spectacle of everyone resembling Star Wars stormtroopers in pursuit of better skin is amusing, the question remains – does exposing your skin to such light truly make a difference, or is it just a gimmick?

To delve into this query, we sought the insights of board-certified dermatologists to evaluate whether at-home LED light therapy masks can genuinely improve your skin. Here’s everything you need to know about at-home light therapy masks, from potential benefits and risks to tips for achieving optimal results.

What are LED Light Therapy Masks, and How Do They Work?

LED light therapy masks are wearable devices emitting different wavelengths of light to address various skin issues. They work by utilizing the wavelengths to target different chromophores in our skin, stimulating cellular activity and functions, thereby producing specific outcomes in our skin.

In a more scientific sense, the photons or light particles released by LEDs in the mask are absorbed by light-sensitive receptors in skin cells, initiating a process known as photobiomodulation. This process results in numerous biological changes in the skin, including accelerated wound healing, synthesis of collagen and elastin, elimination of acne-causing bacteria, and reduction of excessive pigmentation.

The duration of at-home light therapy mask usage varies depending on the product and manufacturer but typically ranges from 10 to 20 minutes per session. It’s essential to note that at-home light therapy masks may not be as potent as professional treatments in dermatologists’ offices, and the intensity and effectiveness of light therapy may vary between devices.

Potential Benefits of LED Light Therapy Masks for Different Skin Conditions

At-home light therapy masks have made light therapy treatments more popular and accessible. However, dermatologists using LED lights for skin treatments have been around for a while. Here, board-certified dermatologists break down the subtle differences:

  • Red Light: Most commonly used for its anti-aging effects, stimulating collagen production and reducing the appearance of fine lines and wrinkles.
  • Blue Light: Effective in reducing inflammation due to its antibacterial properties, aiding in preventing future acne breakouts by targeting acne-causing bacteria.
  • Green Light: Often used to minimize excessive pigmentation and even out skin tone, targeting cells responsible for melanin production and helping break down excess pigments in the skin.
  • Yellow Light: Known for its soothing and calming effects on the skin, helping reduce redness, inflammation, and irritation. Beneficial for individuals prone to rosacea or with sensitive skin.
  • Infrared Light: Penetrates deeper into the skin than other colors, commonly used to improve blood circulation, reduce inflammation, and promote wound healing.

Potential Risks and Side Effects of LED Light Therapy Masks

Experts generally agree that using at-home light therapy masks poses no significant risks. Concerns about facial burns are unfounded, as the infrared radiation from these masks only heats facial tissues without any risk of burns. Emphasizing the importance of purchasing at-home light therapy masks from reputable suppliers, ideally with approval from the U.S. Food and Drug Administration (FDA).

Protecting your eyes is crucial when using at-home light therapy masks; use the protective eyewear provided with the mask. Follow the manufacturer’s instructions for device operation. If your mask does not include protective eyewear, consider purchasing a suitable pair.

For individuals with sensitive skin or those taking certain medications, at-home light therapy masks may not be the best choice for their skin. While light therapy is generally well-tolerated, some may experience mild, temporary side effects such as redness, dryness, or irritation, which typically subside shortly after treatment.

Reviewing Scientific Evidence: Are LED Light Therapy Masks Effective?

Despite being relatively new, preliminary research results on at-home light therapy masks are promising. Several published studies indicate that LED masks treat fine lines and aging issues by increasing collagen, improving skin elasticity, and clearing acne. A study published in the “Journal of Dermatological Research” found that at-home LED masks effectively reduced signs of aging.

However, most dermatologists believe that at-home light therapy masks are not a shortcut or a cure-all for skin issues. While they may be beneficial, the prerequisite is having a solid skincare routine already in place and consistently adhering to it. If you don’t habitually use sunscreen and retinoids, don’t rely on light therapy to turn back the clock on your skin.

Are LED Light Therapy Masks Worth the Investment?

To make at-home light therapy masks worthwhile, they must be used in conjunction with a skincare regimen, including proper cleansing and moisturizing, consistent SPF application, and retinoid use. It’s equally important to note that results take time to materialize.

These devices are generally safe as they use lower energy, implying that results will require more extended periods. Therefore, patience and consistency are key when using these devices.

Like any new skincare product, consult with a dermatologist to understand the different types of masks available and determine which is best suited for your skin type and concerns. Your healthcare provider will be the best source of information, especially if you have sensitive skin.
