HOW LONG HAS LASER BEEN USED IN HAIR REMOVAL?
Laser technology began back in 1900 when Einstein formulated the concept of stimulated light emission. This theory was applied to the skin in 1959 by Mairman, who developed the first 694nm, monochromatic light laser.
In 1963, a dermatologist named Leon Goldman began to treat different skin conditions using the ruby laser.
In the 1980s, Anderson and Parrish developed the principle of selective photothermolysis, which greatly improved and boosted the use of laser technology.
In 1988, the effects of ruby laser in permanent hair removal were published by Dierickx for the first time. In 1995, Goldberg used the Nd:YAG laser for hair removal. From this moment on comparative studies were carried out to demonstrate the efficacy of laser hair removal, being Nestor’s work in 1998 one of the most significant, with more than 2000 treated cases. Other authors who have proven its efficacy are: Goldberg et al. in 1997, Bjerring et al. in 1998, Grossman in 1999, Campos et al. in 1999, etc.
