Recovery effects of various skin lipid components and their structural derivatives on skin barrier damage

This study compares the skin barrier recovery effects of skin lipid components, demonstrating that BA elicits a high skin barrier recovery effect similar to that of CER, which has known efficacy. BA also had an excellent sealing effect through lipid packaging, whereas CER had a combined sealing effect and increased the epidermal thickness and density. These results provide foundational evidence for formulating products that help restore the skin barrier by supplying lipids to the skin surface.
