13 Jun 2023 --- Biological Science Research Division of Kao Corporation has revealed that eucalyptus and bilberry extracts can enhance the skin barrier. The company finds that the decline of autophagy activity – cellular recycling process – in the skin adversely affects epidermal homeostasis and disturbs the formation (cornification) of the stratum corneum, which is the skin’s barrier that retains hydration. Autophagy means “self-eating,” which is a natural process in all cells in the human body, where unwanted or dysfunctional proteins are degraded into amino acids. These amino acids are then recycled to create new proteins. When the process decreases in the skin calls, it affects skin appearance.
