The efficacy and tolerance of the 650-microsecond 1064-nm Nd:YAG laser (Aerolase Neo Elite) is equivalent to the excimer laser for the treatment of mild to moderate psoriasis vulgaris of the arms and legs.

The efficacy and tolerance of the 650-microsecond 1064-nm Nd:YAG laser (Aerolase NeoElite) is equivalent to the excimer laser for the treatment of mild to moderate psoriasis vulgaris of the arms and legs, according to a new study in the Journal of Drugs in Dermatology.  

The authors used the Aerolase NeoElite laser for the study, and it is the only laser with the stated parameters.  

The 650-microsecond Nd:YAG 1064nm laser offers unique features not available in other devices, points out study author ark Nestor, MD PhD. Dr. Nestor is Director of the Center for Clinical and Cosmetic Research and the Center for Cosmetic Enhancement in Aventura, Florida. For example, its 650-microsecond pulse duration causes minimal pain during treatment of skin of color without anesthetic or skin cooling. Since the pulse duration is shorter than the thermal relaxation time of both the skin and blood vessels, the therapeutic target is heated more rapidly than the rate heat is conducted to the surrounding skin, thus reducing damage and lowering the risk of pigmentary alterations. 

Moreover, the 650-microsecond laser also delivers energy in a collimated beam, so the operator may vary handpiece-to-skin distance without changing the fluence. This enhances both efficacy and safety during treatment and renders treatment less dependent on operator technique.

Further clinical research on psoriasis using the Aerolase Neo Elite laser is being conducted. "Excellent psoriasis outcomes is a core competence of Aerolase, and we are raising the standard of care for that disease state," says Pavel Efremkin PhD, Chairman and CEO of Aerolase, in a news release.
