Bovine elastin peptide is a small molecule peptide supplement extracted from bovine elastin. Elastin is an important structural protein that gives skin elasticity and structural support. When elastin is broken down into small molecule elastin peptides, it is more easily absorbed by the body. Taking bovine elastin peptides may help promote skin elasticity, reduce signs of aging, and improve skin health. It is commonly used in skin care products and dietary supplements to support collagen production and maintain youthful skin.
