Objective To evaluate the effects of Q-switched Nd: YAG laser in the treatment of freckle. Methods Fourty-seven cases treated by Q-switched Nd: YAG laser between October 2004 to August. 2007 were analyzed. The effects of post-laser treatment of tetracaine gel were evaluated. Results Of 47 cases, 38 were cured (80.9%), 8 were notablely improved (17.0%) and 1 was improved 6 months after treatment. The total efficient rate was 100%. All of them were cured 1 year after treatment. 15 cases had a postinflammatory hyperpigmentation 3 months after the laser treatment which disappeared in 9 months. Furthermore, when the tetracaine gel was used after the laser treatment, the onset time was 20 to 70 seconds, the time of the maxial decreased-pain was 2 to 5 minutes and the maximal decreased-pain was 70%～100%. Conclusions Frequency-doubled Q-switched Nd: YAG laser is an effective tool to treat freckles without any adverse effects. But some of the patients will have a reversible postin-flammatory hyperpigmentation. Tetracaine gel has a rapid and good effects on laser-induced pain when used immedi-ately after laser procedure.
