ABSTRACT:
A long pulse alexandrite laser hair removal system is disclosed using light pulses of greater than 1 msec and fluences between 10 and 50 J/cm.sup.2. The use of an alexandrite laser allows good penetration while still achieving an acceptable combination of hemoglobin and melanin absorption. The use an index-matching application on the skin sections to be treated is also described. This substance will be absorbed into the epidermal layer to provide better coupling of the laser light into the skin. Also, and most advantageously, it will reduce reflections at the epidermal-dermal junction, which can lead to the damage of the skin. Also a topical thermal or photochromic indicator is suggested since skin irradiation in the near-infrared generally does not produce any characteristic skin color change as is found when using pulsed dye lasers, for example.
