Abstract: Objective To compare the effect of Q-switch Nd ∶ YAG laser and intensive pulsed light on freckles.Methods 80 patients with freckles were divided into 2 groups randomly.One group of patients were treated with Q-switch Nd ∶ YAG 532 nm frequency-doubled laser,the interval was 8 weeks.The other group of patients were treated with 570 nm intensive pulsed light,the interval was 8 weeks.Results We used Mann-Whitney U test to compare the curative effect of the two groups (P ＜0.05),and the mean rank (34.00) of the Q-switch Nd;YAG laser treatment group was greater than that (47.00) of the intense pulsed light treatment group.Conclusions The curative effect of Q-switch Nd ∶ YAG laser is better than that of intensive pulsed light on freckles.
