How Low-Level Light Therapy Works

Wavelengths of red light (at 650-670nm) have been shown to help improve the skin's barrier function by strengthening its ability to retain key elements it needs to heal and generate new collagen after its production has slowed due to age or cumulative damage. Red light low-level LEDs are also believed to target the skin's oil glands to reduce cytokines, a class of pro-inflammatory substances believed to play a role in chronic acne.

Low-level red light is effective in helping to reduce signs of aging, including fine lines and wrinkles. This wavelength appears to be a popular choice for those struggling with both acne and wrinkles. There is minimal risk of side effects, especially when used without light-activating chemicals. Many dermatologists heavily rely on low-level red light therapy to treat rhytids (wrinkles), rosacea, scarring and eczema.

To treat facial fine lines and wrinkles, the iDerma Facial Beautification System will administer low-level red light at 650 to 670nm. This wavelength range of red light causes the cells to produce chemicals called cytokines, which then trigger the fibroblasts or collagen-producing cells that, in turn, help heal the skin and plump up problem areas.
