Description

Technical field

[0001] The present invention relates to ceramide production promoters and moisturizers that can increase ceramides and restore the barrier function and moisturizing function of the skin. Background technique

[0002] Ceramide, one of the sphingolipids, is a trace amount of lipid in the entire organism, but accounts for more than half of the lipids in the stratum corneum, the outermost layer of the skin, and plays an important role in the skin's moisturizing and barrier mechanisms. . This ceramide is secreted by epidermal cells and then functions by building a lamella structure between cells in the stratum corneum.

[0003] However, there are many reports that in skin diseases such as dry skin, rough skin, atopic dermatitis, senile xerosis, and psoriasis, the healthy metabolism of ceramide is hindered, resulting in keratin The amount of ceramide in the skin layer is reduced, causing the skin's moisturizing function and barrier function to decline.
