Glycerol production promoter derived from Staphylococcus epidermidis, antibacterial peptide production promoter derived from skin epidermis keratinocytes, and their use as an external preparation for skin protection

摘要

Provided are: a skin-protecting agent and an external preparation for skin protection, which not only synergistically work in combination with a plant polysaccharide but also has an effect of promoting the production of glycerol derived from Staphylococcus epidermidis, which is a skin resident bacterium useful on the skin, and the production of antimicrobial peptides derived from skin epidermal keratinocytes and exhibits excellent effect of improving the touch feeling when applied to the skin.　More specifically, the present invention provides a skin protective agent and an external preparation for skin protection, which comprise a lactic acid bacterium belonging to the genus Enterococcus.
