The decreasing effect of wrinkle on the pressure sensitive adhesive hydrogel patches containing ulmi cortex extract and sorbitol as the drug for anti-wrinkle were investigated. In this study, hydrogels were prepared by the crosslinking reaction of acrylic polymers and aluminum ions produced by L(+)-tartaric acid hydrolysis of the dihydroxy aluminum aminoacetates. The inhibition concentration of ulmi cortex extract on the collagenase exhibited at 0.01%. Furthermore, the moisturizing effect of hydrogel patches formulated with sorbitol was higher than that without it. In vivo animal test in hairless mouse showed that the ulmi cortex-loaded hydrogel patches had about 31.2% of anti-wrinkle effect compared to blank (before attaching the patches). Human test showed that only 33% of subjects showed the decreasing of wrinkle during 8 weeks. In conclusion, the model pressure sensitive adhesive hydrogel patches in this study would be pharmaceutically applicable for the wrinkle treatment on the facial skin.
