The invention belongs to the field of cosmetics research and development, and particularly relates to application of rat tail collagen in the field of cosmetics. Compared with conventional collagen onthe market, in addition to the characteristics of general collagen, the rat tail collagen has the advantages of stable triple helix structure, high collagen activity and low immunogenicity; the source quality is controllable, the biosafety is high, and the reduction of biological activity by radiation sterilization is not needed; through experimental determination, the rat tail collagen preparedaccording to the technical scheme has the performance of whitening, melanin synthesis inhibition, anti-oxidation, anti-allergy, hormone skin repair and acne removal. The application of the rat tail collagen in the field of cosmetics overcomes the technical defect that the quality of the cosmetics is seriously affected due to addition of toners, flavoring agents, stabilizers and preservatives intocollagen-containing cosmeti
