Curious about how LED light therapy can transform your skin?
The treatment uses different wavelengths of LED light to penetrate the skin at various depths, effectively combating acne, inflammation, signs of aging, promoting collagen and elastin production (proteins that help improve skin elasticity and reduce wrinkles), and even aiding in the healing of minor wounds.
Keep reading to discover everything you need to know about its effectiveness, safety, how often you should use the LED mask, and how it fits into your skincare routine!
What is LED light therapy?
LED (Light-Emitting Diode) light therapy is a non-invasive treatment that penetrates the skin’s layers to improve the skin’s appearance and health.
Using LED technology, the skin absorbs light energy, which triggers cellular changes through a process called photobiomodulation (PBM). This process influences gene expression and cellular functions, resulting in various effects on the skin that are not yet fully understood.
Studies show that PBM is effective for skin rejuvenation, aimed at improving the overall appearance of the skin by reducing fine lines and wrinkles and improving skin texture, skin tone, and dyspigmentation (1). The energy of LED light helps improve skin elasticity and pore contraction, thereby preventing wrinkles (2).
Advantages of the LED facemask include its efficacy, safety, convenient home-based use, minimal associated downtime, simple operation, non-invasiveness, and appreciable results in as few as 6 weeks (1).

Take a look at an Advanced LED Therapy Mask available at Augment Life Shop:
Our Advanced LED Therapy Mask features 4 targeted light modes, each designed to deliver maximum skin benefits:
- 440 nm (Blue Light) – Reduces acne by targeting bacteria that cause breakouts.
- 590 nm (Yellow Light) – Soothes skin, reduces redness, and improves circulation.
- 630 nm (Red Light) – Boosts collagen production, minimizing fine lines, scars, and wrinkles.
- 850 nm (Near-Infrared Light) – Penetrates deep to promote healing and skin regeneration.
When to use an LED face mask in routine
LED face masks can be a beneficial addition to your skincare routine. Keep in mind that these work best to supplement a well-rounded routine of in-office treatments, a thorough skin-care routine, and consistent use.
- Cleanse the skin: Before using an LED mask, it is recommended to start with a clean and dry face to ensure the skin is prepared for optimal light penetration. Gently remove any makeup, dirt, or impurities from the skin through gentle cleansing.
- Use before applying skincare products - It is generally advised to use the LED mask before applying any skincare products that you typically use in your routine, such as moisturizers, serums, or treatments. This allows the LED light to penetrate the skin better.
-
Adjust according to your specific needs - LED masks can be used at different times in a skincare routine depending on your skincare goals. You may use it in the evening as a relaxing, calming part of your nighttime routine or in the morning routine to kickstart the day.
How often should you use a red light LED mask on your face?
For the best results, dermatologists recommend using a red light LED mask three to five times a week for at least 12 weeks to see the best results.
The recommended frequency of LED mask usage can vary depending on the specific device and instructions provided. It's important to follow the guidelines provided to avoid improper use and ensure the best results for your skin.
Can I use LED face mask every day?
LED light therapy has been proven to be effective and safe when used daily for several weeks in controlled clinical trials. However, none of the studies specifically recommend daily use for extended periods. If you are considering using it daily for extended periods, it is a good idea to consult a dermatologist.
Can I use LED face mask twice a day?
Using LED face mask twice a day is generally not recommended.
LED face mask side effects
The LED light source has a narrow wavelength line and emits a light source of a specific wavelength; therefore, harmful ultraviolet (UV) rays or infrared (IR) rays are not emitted (2).
In a clinical study on LED red light therapy, the safety of different energy levels was evaluated. It was found that higher energy levels (480–640 J/cm²) could cause side effects such as blistering and prolonged redness (3).
However, these higher energy levels are not used in LED face masks designed for home use. Most consumer LED masks typically operate at much lower energy levels, around 10–100 J/cm², which are safer and less likely to cause adverse effects.
A recent study found that the red (630 nm) and infrared (850 nm) light emitted by LED masks does not harm skin tissue or eyes due to its low energy levels (2).
Although LED face masks are generally considered safe for skin treatments, they can pose risks to eye health, particularly when using blue light therapy.
A case report documented retinal damage (photochemical retinopathy) in a 37-year-old woman who used a blue LED face mask without eye protection. She experienced distorted vision due to prolonged exposure to blue light at 460 nm (4).
This case demonstrates that retinal damage can occur in humans due to prolonged exposure to blue light. Hence, it is important to be wary of eye exposure and ensure the eyes are covered during LED face mask use (4). Experts recommend wearing protective goggles or keeping your eyes closed during treatments, especially with blue light therapy.
LED face masks are generally very safe when used correctly. However, some individuals may experience mild redness, dryness, or irritation after use, but this is typically temporary and should resolve quickly.
Using it too frequently or for extended periods beyond the recommended guidelines can lead to skin irritation, dryness, or even potential light sensitivity over time. More frequent use won’t provide better results and may have the opposite effect, so it’s essential to follow the advised usage.
Final Recommendations
LED masks are generally suitable for most people, but those with photosensitive conditions (like lupus), individuals taking medication that increases light sensitivity, or those with active skin infections should avoid using LED masks. Light therapy can potentially worsen these conditions or lead to an adverse reaction.
In conclusion, while LED face masks emitting red (630 nm) and infrared (850 nm) wavelengths are generally regarded as safe for the eyes when used properly, LED masks emitting blue (440 nm) light should be used with caution due to the potential risk of retinal damage. Yellow light (590 nm) is generally considered safe for the eyes due to its longer wavelength, but taking protective measures during treatment is still advisable because of the lack of clinical studies on its specific ocular effects.
Always follow the manufacturer's instructions, use protective measures such as goggles, and avoid overuse to ensure safety during treatments.
