The principle of hair removal is based on the Selective Photothermolysis (SPTL) theory. This theory explains laser as a method that induces localized tissue damage without affecting surrounding tissue. Essentially, when light of appropriate wavelength is directed onto the treatment area, melanin in the hair follicles, rather than other tissues, selectively absorbs the light and converts it into heat. This damages the follicles responsible for hair growth, resulting in hair reduction or permanent removal.

808nm wavelength semiconductor laser goes through our skin and directly arrives at the melanin in the hair follicle with little absorbed by other tissues. The heat energy transformed from the light will burn and destroy only follicles, so as to avoid skin burn and lessen skin hyper-pigmentation. It is safe and effective.The device uses 808nm diode laser technology, which is known as the gold standard for permanent hair removal with optimal results

Both diode lasers and IPL are used for hair removal by targeting the hair follicle and preventing further hair growth. However, diode lasers are often considered to be more effective and precise than IPL for hair removal, especially on darker skin types, as they can specifically target the melanin in hair follicles while leaving the surrounding skin unharmed. The maximum energy density of diode lasers is five times that of IPL.

Diode laser hair removal destroys hair follicles by targeting melanin whereas YAG laser hair removal penetrates the hair through the skin cells. This makes diode laser technology more effective for coarse hair and requires a shorter recovery time.

IPL laser hair removal will most likely require more than one session, while using a diode laser may work more effectively. Diode laser hair removal is more comfortable because of the integrated cooling and treats more hair and skin types, whereas IPL is best suited for those with darker hair and lighter skin.
