Abstract
This study was conducted to confirm the suitability of hydrogen as a functional cosmetic ingredient by evaluating the anti-aging and whitening effect of hydrogen, known as an excellent antioxidant. Cosmetic hydrogen powder was prepared to investigate its inhibitory activity on elastase, collagenase, and tyrosinase, and a hydrogen pack was produced using the prepared cosmetic powder to conduct clinical trials. The results showed that hydrogen powder had excellent anti-aging activation and whitening effect. In clinical trials, skin elasticity was increased by 15%, skin sagging decreased by 4.53%, and skin tone improved by 4.86%, compared to the control group. These results suggest that hydrogen has excellent anti-aging and whitening effect. Therefore, it is highly likely that hydrogen can be used as a functional cosmetic ingredient for wrinkle improvement and skin whitening.
Highlights
According to the free radical theory of aging, free radicals cause aging by damaging cells and inducing oxidative stress [1]
In this study, we evaluated the in vitro skin antiaging and whitening effects using hydrogen powder and conducted a clinical test to demonstrate the beneficial effects of hydrogen on the skin

Summary
According to the free radical theory of aging, free radicals cause aging by damaging cells and inducing oxidative stress [1]. The human body is constantly exposed to free radicals owing to metabolism occurring in organelles, such as mitochondria and endoplasmic reticulum [2]. Among these free radicals, hydroxyl (HO·) and peroxynitrite (NO3·) radicals are the most dangerous and powerful radicals, which attack the main components of the human body, including DNA, protein, and lipids. Hydroxyl (HO·) and peroxynitrite (NO3·) radicals are the most dangerous and powerful radicals, which attack the main components of the human body, including DNA, protein, and lipids This causes permanent damage and lead to aging[3] Many studies have already investigated the antioxidant activity of hydrogen. We believe that this study willfacilitate the development of new functional cosmetics in the future
