About
Serum protein — typically albumin/globulin fraction from (bovine) blood serum. Raises significant ethical, regulatory and safety concerns.
Serum protein in a cosmetic INCI sense refers to the soluble protein fraction from animal blood serum, usually bovine (albumin, globulins, transferrin). Its cosmetic role is generic skin conditioning. Bovine blood-derived materials are subject to strict EU TSE/BSE sourcing (Commission Regulation 1774/2002 and cosmetic-Regulation Annex rules), and supply requires documented certification. Independent of regulatory paperwork, blood-origin ingredients carry ethical, microbiological and public-acceptance concerns, and the literature on cosmetic efficacy is sparse.
