摘要

PURPOSE: A cosmetic composition for preventing and treating atopic dermatitis is provided to treat atopic dermatitis using a fermented Ledum palustre var. diversipilosum liquid, and to quickly penetrate active ingredients to the skin by nanotechnology. CONSTITUTION: A cosmetic composition for preventing and treating atopic dermatitis contains a Ledum palustre var. diversipilosum liquid which is prepared by fermenting a Ledum palustre var. diversipilosum extract with lactic acid bacteria. A method for manufacturing the cosmetic composition comprises: a step of preparing a nanoextract of Ledum palustre var. diversipilosum containing nanoparticles of Ledum palustre var. diversipilosum; a step of mixing the nanoextract with a lactic acid bacteria culture medium; and a step of inoculating two or more kinds of lactic acid bacteria into the lactic bacteria culture medium and fermenting. The lactic acid bacteria are selected from the group consisting of Enterococcus faecium, Enterococcus faecalis, Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus lactis, Lactobacillus rhamnosus, Lactobacillus sakei, Lactobacillus brevis, Lactobacillus graminis, Leuconostoc citreum, Weissella hellenica, Lactococcus garvieae, Pediococcus pentosaceus, Pediococcus acidilactici, Bifidobacterium animalis, and Bifidobacterium infantis.
