Effects of Vitamin C and SH-Polypeptide-10 Cosmetic Ingredients on Wrinkle Improvement and Skin Whitening

Abstract

In this study, 20 female subjects in their 30s to 50s used cosmetics containing the main ingredients vitamin C and SH-Polypeptide-10 in an environment exposed to ultraviolet rays, and underwent clinical trials to determine the effects of improving wrinkles, brightness, and whitening of the skin. Efficacy evaluation was performed. Wrinkles around the eyes significantly decreased from 0.0592 to 0.0507(p<0.001), and the wrinkle improvement effect decreased by 16.78%(p<0.05). Skin brightness significantly decreased from 65.44 to 67.04 in the experimental group(p<0.001), and skin brightness increased by 2.45%(p<0.05). Additionally, the skin whitening effect significantly decreased from 66.38 to 55.51(p<0.001), and melanin pigment decreased by 19.57%(p<0.05). The cosmetics used in this experiment were shown to have antioxidant effects that protect cells from oxidative stress, increase transdermal permeability, promote epidermal cell growth and cell regeneration, inhibit tyrosinase activity and promote collagen formation. Overall, the use of cosmetics containing vitamin C and SH-Polypeptide-10 as main ingredients resulted in significant improvement in the experimental group, which can be seen as having a positive effect on improving wrinkles around the eyes and skin whitening.
