The Apex's 800 nm wavelength provides the ideal balance of penetration depth and absorption for clinical efficacy and safety in a variety of skin types.

Laser hair removal uses melanin, which absorbs broadly across the optical spectrum, as the target. Melanin is found in the bulb of the hair, the hair shaft and parts of the root sheath. The limiting factor in selecting melanin as the target for laser hair removal is that melanin is also found in the epidermis and that hair pigmentation varies widely. The ideal wavelength should have sufficient melanin absorption to injure the hair follicle, but should also allow laser light to penetrate through the epidermis to the 4-6mm depth needed to injure the hair bulb. The Apex's 800 nm wavelength appears to provide this balance.
