The present disclosure provides an exosome composition comprising a population of enriched exosomes. The exosome composition is directly obtained by isolation and ultrafiltration rather than by formulation. The present disclosure also provides a method for producing the exosome composition.

Disclosed is a cosmetic composition for skin soothing. The cosmetic composition includes, as active ingredients, exosomes derived from naturally occurring deer antler velvet. The cosmetic composition can effectively soothe the skin whose condition has been abnormally altered (such as atopic dermatitis, inflammation, erythema, oxidation, cytotoxic agents in the skin, loss of moisture, melasma, itching, roughness or wrinkles) by various causes.
