![]() No identifiable health information was included in this case report. We report a case of photochemical retinopathy after the long-term use of a blue LED face mask in a 37-year-old woman who was treated with intravitreal bevacizumab injection. However, to our knowledge, there have been no reports of retinal damage caused by long term exposure to blue light in the human eye. Therefore, the short wave length of the blue light LED itself can cause the retinal damage. The LED-induced retina damage is known to be wavelength -dependent rather than energy-dependent. In mouse model, retinal damage was observed when exposed to blue LEDs for 2 hours. ![]() However, many animal studies have shown that intensive blue light can cause retinal cell damage and alter blood retinal barrier function. It has antibacterial and anti-inflammatory properties, and is mainly used for skin diseases such as acne. īlue light has a wavelength of 400 to 470 nm and its tissue penetration depth is low because of its short wavelength. Red and infrared light, which have relatively long wavelengths, penetrate deep into the tissue and facilitate the regeneration of dermal structures, such as adnexa and fibroblasts. Generally, the red LED emits light at a wavelength of 630 to 700 nm, while the infrared LED emits a wavelength of 800 to 1200 nm. Recently, LED face masks for facial skin rejuvenation have been widely introduced to the market. In general, light in the spectral range from 600 to 1300 nm is useful for promoting wound healing, tissue repair, and skin rejuvenation. The depth of tissue penetration and the target site of treatment change depending on the wavelength of the LED light. Altering cellular function using low-energy, non-thermal light-emitting diodes (LEDs) light is known as photobiomodulation.
