Light emitting diode (LED) light therapy is a non-invasive therapy that digs deeper into the skin and improves its health.
Led (light-emitting diode) light therapy is a non-invasive treatment that enters the skin’s layers to improve the skin. It uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle missions and later found it to have promise for wound treatment. Skin specialists often use led light therapy together with other treatments, such as creams, ointments and facials, to give you the best results.
Led light therapy is mainly focused on skincare, promoting anti-aging effects and reducing inflammation. There are different wavelengths of the visible light spectrum, each corresponding to different colors and penetrating the skin to different depths. It is thought that led light produces different effects depending on the level of skin it penetrates.
Red light: Red, or infrared, light is used for treating the epidermis, which is the outer layer of skin. When the light is applied to your skin, the epidermis absorbs it and then stimulates collagen proteins. In theory, more collagen means that your skin will look smoother and fuller, which can reduce the appearance of fine lines and wrinkles. Red led light is also thought to reduce inflammation while improving circulation, which can give you a healthier glow.
Blue light: Blue led light therapy, on the other hand, targets the sebaceous glands, which are also called oil glands. They’re located beneath your hair follicles. Sebaceous glands are necessary for lubricating your skin and hair so that it doesn’t dry out. However, these glands can become overactive, leading to oily skin and acne. The theory is that blue led light therapy can target these oil glands and make them less active. In turn, you may see fewer acne breakouts. Blue light can also kill acne-causing bacteria beneath the skin, which can help treat severe acne pimples, including cysts and nodules. One 2018 animal study trusted source found that blue led improved healing of third-degree skin burns.
