Bone collagen, a natural protein, has a very important impact on the skin. Bone collagen can significantly increase the elasticity and firmness of the skin, restoring a youthful state to the skin. It can stimulate the regeneration of skin cells, enhance skin vitality, effectively improve skin texture, and make the skin more compact and elastic. At the same time, collagen can also enhance the skin's water retention ability, reduce water loss, and keep the skin always hydrated. In addition, collagen can provide necessary nutrients to help repair and renew the skin, forming a protective film that effectively prevents damage from the external environment.
