Abstract

BACKGROUND: The need for using sunscreen is increasing today, but we know little about the effect of sunscreens on the skin of Korean people.
OBJECTIVE
We tried to estimate and compare the SPF of 8% homomenthyl salicylate lotion, which was recommended as the control in SPF experiments by the FDA, USA, in Koreans according to different light sources.
METHODS
After application of 8% homomenthyl salicylate lotion to the back, 33 men of the third decade were irradiated by xenon arc solar simulator or by fluorescent sunlamp, We estimated the SPF of them 24 hours later.
RESULTS
The SPF of 8% homomenthyl salicylate lotion was 4.8+/-0.8 with the solar simulator, 2.7+/-0.6 with the fluorescent sunlamp.
CONCLUSION
We confimed that the SPF of 8% homomenthyl salicylate lotion with xenon arc solar simulator can be used as a control value in Koreans, and found out that the SPF with the fluorescent sunlamp was significantly lower than that with the xenon arc lamp. So it should be taken into consideration that differences of SPF according to light sources exists in studying sunscreens.
