Abstract
BackgroundConspicuous facial pores are therapeutic targets for cosmeceuticals. Here we examine the effect of topical fullerene on conspicuous facial pores using a new image analyser called the VISIA® system. Ten healthy Japanese females participated in this study, and they received applications of 1% fullerene lotion to the face twice a day for 8 weeks.FindingsFullerene lotion significantly decreased conspicuous pores by 17.6% (p < 0.05, Wilcoxon signed-rank test) after an 8-week treatment. A self-administered questionnaire indicated that this reduction achieved cosmetically appreciable effects. In addition, to investigate the mechanism of effect of fullerene, we examined its effect on UVB-induced prostaglandin E2 (PGE2) production in reconstructed human epidermis (RhE). The results showed that irradiation of RhE with 1000 mJ/cm2 increased PGE2 production by 62.3% (p < 0.05, Mann-Whitney U-test) and the addition of 28 μM fullerene significantly suppressed the UVB-induced PGE2 production by 18.3% (p < 0.05).ConclusionsFullerene lotion significantly decreases conspicuous facial pores after an 8-week treatment possibly through the suppression of PGE2 production in the epidermis.

Summary
Conspicuous facial pores are therapeutic targets for cosmeceuticals. Here we examine the effect of topical fullerene on conspicuous facial pores using a new image analyser called the VISIA® system. Conclusions: Fullerene lotion significantly decreases conspicuous facial pores after an 8-week treatment possibly through the suppression of PGE2 production in the epidermis.
