Collagen is the most abundant structural protein in the human body, primarily found in connective tissues such as skin, bones, and tendons. It provides strength and elasticity to the skin, playing a crucial role in maintaining skin integrity and resilience.
Collagen supplementation may stimulate fibroblast activity, leading to increased collagen synthesis and improved skin elasticity.
Collagen peptides may enhance the skin's moisture retention capacity by promoting extracellular matrix components.
By increasing dermal collagen density, collagen supplements may reduce the appearance of wrinkles.
