Thirty-four people with mild to moderate facial acne were enrolled and subsequently randomized to undergo three, 2-week interval treatments with 1064-nm Nd:YAG on one side of the face and 595-nm PDL on the other side. In mild to moderate facial acne vulgaris,1064-nm Nd:YAG and 595-nm PDL treatments are equally effective in decreasing inflammatory acne lesions and acne erythema.
