That’s where supplements like collagen powder come into use. “Collagen powder is made from animal tissue, primarily the skin and bones,” explains dermatologist Dr. Peterson Pierre. “The protein is processed into a gelatinous form, which is further hydrolyzed into peptides to make the protein easier for your body to absorb.” Pierre explains that “collagen peptides can potentially benefit the skin by increasing hydration and elasticity while reducing fine lines and wrinkle depth.”
