Lasers in Dermatology

“…[7][8][9][10][11][12][13][14][15][16][17][18][19] Longer pulsed, normal-mode ruby lasers have been shown to be useful for hair epilation and some congenital nevi. Because melanin is selectively targeted at 694nm, the QSRL can be used to eradicate a variety of epidermal and dermal pigmented lesions.…”

“…Because melanin is selectively targeted at 694nm, the QSRL can be used to eradicate a variety of epidermal and dermal pigmented lesions. [17][18][19] Laser treatment of mixedtype (epidermal/dermal) pigmented lesions such as café-au-lait macules, Becker's nevus, and nevus spilus are more difficult to eradicate and have a higher rate of recurrence than do purely epidermal or dermal lesions. [20][21][22][23][24] Superficial (epidermal) pigmented lesions such as solar lentigines and ephelides can be significantly lightened or completely eradicated within 1 to 2 QSRL treatments, [13] whereas deeper (dermal) pigmented lesions such as nevus of Ota, blue nevi, and melanocytic nevi usually require more treatment sessions to achieve similar clinical fading.…”
