Long‐pulsed 755‐nm alexandrite and long‐pulsed 1064‐nm neodymium:yttrium–aluminum–garnet (Nd:YAG) lasers have been used for photorejuvenation of the face. The aim of this study was to investigate the safety and efficacy of long‐pulsed alexandrite and long‐pulsed Nd:YAG lasers for photorejuvenation in Korea. One hundred and sixteen Korean patients with photo‐aged facial skin were enrolled. Sixty‐two patients with facial pigmentation underwent long‐pulsed alexandrite laser treatment. Eleven patients that wanted to improve facial pigmentation with minimal pain had quasi‐long‐pulsed alexandrite laser treatment. Forty three patients had long‐pulsed Nd:YAG laser therapy. Outcome assessments included standard photographs and global evaluation by blinded investigators. The self‐assessment grade was provided in questionnaires. Forty‐four percent of patients reported excellent or good improvement of their pigmentary lesions (>50% improvement) using a long‐pulsed alexandrite laser. Of patients who underwent long‐pulsed Nd:YAG laser treatment, 36% reported excellent or good improvement in skin tightening, 50% in facial flushing and 45% in pigmentary lesions. We conclude that long‐pulsed alexandrite and long‐pulsed Nd:YAG lasers are safe and effective for facial photorejuvenation in Koreans.
