The Q-switched lasers (694 nm ruby, 755 nm Alexandrite or 1064 nm Nd-YAG) with their high peak power and pulse width in nano second range are best suited to treat various epidermal, junctional, mixed and dermal lesions. The Q-switched 1064 nm Nd-YAG is an ideal choice to treat dermal pigment as in nevus of Ota and in darker skin types, as it reduces the risk of epidermal injury and pigmentary alterations.
Q-switched lasers (694 nm ruby, 755 nm Alexandrite or 1064 nm Nd-YAG) with their high peak power and short pulse duration are effective in treating various skin lesions, including those on the epidermis, junctional layer, mixed layers, and dermis. The 1064 nm Nd-YAG laser is particularly suitable for treating dermal pigment issues like nevus of Ota in darker skin types due to its reduced risk of epidermal damage and pigmentation changes.
