Alexandrite laser is 755 nm wavelength laser being used in laser epilation processes thanks to its abilities of targeting the melanin in the hair,  best suction by melaning and minimal damage on surrounding tissue. Alexandrite laser is particularly effective on skin types 1, 2 and 3 (i.e. light skin persons) whereas may also be used in a controlled manner for skin type 4 persons. The technology is particularly successful on the thick and dark hairs in armpits, genital areas and legs whereas not so effective on thinner hairs, fluffs and light hairs already weaken after epilation. It should be applied with due diligence on dark-skinned persons and tanned persons.
