Ceramide and/or glucose ceramide generation promoter or humectant

Abstract

The invention provides a ceramide and / or glucose ceramide generation promoter or humectant, which takes a rock tea extract as an effective component.

Description

technical field [0001] The present invention relates to a ceramide and / or glucosylceramide production accelerator or a moisturizing agent. Background technique [0002] Ceramide, one of the sphingolipids, exists in the stratum corneum of the skin and accounts for about 50% of the intercellular lipids in the stratum corneum. Sphingolipid is a general term for complex lipids having a sphingosine skeleton. Glucosylceramide is a kind of sphingolipid formed by binding glucose to ceramide. The ceramide synthesized by epidermal cells is temporarily stored in the form of glucosylceramide or sphingomyelin; it is then excreted outside the cell, where glucocerebrosidase (Glucocerebrosidase) and sphingomyelinase (Sphingomyelinase) Under the action of ceramide, it becomes ceramide again, thereby functioning as an intercellular lipid. [0003] Conventionally, it has been known that sphingolipids such as ceramide, glucosylceramide, and galactosylceramide have effects such as promoting t...
