A noncoherent, broadband, intense pulsed light source has been used for the symptoms of photoaging skin as a nonablative method. The purpose of this study is to investigate the efficacy and tolerability of intense pulsed light in solar lentigines and ephelides on the face. An open study was performed in patients with solar lentigines and ephelides who received three to five treatments of intense pulsed light. Forty-eight percent of patients had more than 50% improvement and 20% had more than 75% improvement. In the group of solar lentigines, 40% of patients showed more than 50% improvement and 16% did more than 75% improvement. Patients with solar 1entigines＋ephelides and ephelides responded remarkably with 75% and 71 % of patients having more than 50% improvement, respectively. Intense pulsed light was well tolerated and may be a new modality for the therapy of solar lentigines and ephelides.

Objectives : The purpose of this study is to report the effect of Q-switched ND:YAG laser therapy along with hominis placenta pharmacopuncture for the patients with Solar lentigines. Methods : The 532nm wavelengths of Q-switched ND:YAG Laser was used to irradiate to the solar lentigines once, choosing an energy that would produce an adequate change in skin color. Also 5cc of hominis placenta pharmacopuncture were injected into both Cheonchu(ST 25). Results : After the treatment with Q-switched ND:YAG laser therapy along with hominis placenta pharmacopuncture, solar lentigines were effectively removed. Conclusion : The treatment with Q-switched ND:YAG laser therapy along with hominis placenta pharmacopuncture for the patients with solar lentigines are effective in the eight cases. Futher, additional studies are required to verify its long-term efficacy.

미백제는 기미와 태양광선노출에 의한 색소침착반과 같은 색소불균형이 주로 나타나는 동양 여성들에 특히 관심이 많다. 이러한 색소침착의 불균형은 UV에 의해 더 심해지기 때문에 미백제는 멜라닌합성을 억제시키거나 UV에 의해 활성화된 signal을 억제함으로써 효과가 나타난다. Eumelanin은 UV에 의해 유도된 DNA 손상을 보호하므로 UV에 의해 유도된 DNA손상을 감소시키는 물질이 이상적인 미백제가 된다. 새롭게 합성된 항산화제인 $\alpha$-tocophenyl ferulate의 효과는 UV에 의해 손상된 DNA damage에 의한 보호 효과와 멜라닌 합성을 억제시킴으로서 나타난다. Chemical peeling과 복합적으로 색소 반점을 치료하는 lightning agent의 효과에 대한 결과를 보고하였으며 색소 반점의 개선을 정량적으로 평가하는 새롭게 개발된 facial image analyzer를 소개할 것이다.
