Long pulse 1,064‐nm neodymium‐doped yttrium aluminum garnet laser in aesthetic dermatology

Abstract

Long pulse 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is a very versatile laser due to its deep penetration and absorption by hemoglobin, melanin, and water, which has gained increasing popularity over recent years for the treatment of leg veins and permanent hair removal as well as skin rejuvenation. The long-pulse Nd:YAG laser was appointed as treatment of choice for the treatment of 0.5-3.0 mm deoxygenated, unsightly leg veins. Hair removal is another application of long pulse Nd:YAG lasers, and decreased light absorption by melanin at 1,064 nm reduces the risk of pigmentary side effects, which makes long pulse Nd:YAG laser the safest laser in darker skin types. The long pulse Nd:YAG lasers are also being employed for skin rejuvenation based on their ability to heat dermal water and stimulate collagen production. We have reviewed the parameters of Nd:YAG laser and shared our experiences in these indications that may be useful for good clinical response with minimal side effects.
