Are At-Home LED Masks Safe?

Dr. Morgan Rabach, board certified dermatologist and co-founder of LM Medical, says that LED, or light emitting diode therapy, is a skin care treatment that uses varying wavelengths of light. Dr. Ava Shamban, board certified dermatologist and founder of Ava MD Dermatology and the Skin Five by Ava MD Clinics, adds that LED therapy can be referred to as "photo rejuvenation" or "light therapy."

Shamban says that generally the skin care treatment uses infrared light transmitted through bulbs in varying wavelengths. The different wavelengths are different colors and each one sends messages to the layers of skin to trigger a specific and expected reaction. The most common wavelengths are red and blue. (Some devices have green, yellow, white lights, etc.) Red is primarily used for anti-aging while blue light is used for treating acne, says Rabach. LED can also stimulate regeneration and fight inflammation and bacteria, per Shamban.
