Collagen is widely used in the cosmetics and skincare industry due to its ability to improve skin elasticity and hydration. It is a key ingredient in anti-aging creams, serums, and masks, helping to reduce the appearance of wrinkles and fine lines. In the medical field, collagen is utilized in wound care products, such as dressings and gels, to promote tissue repair and regeneration. It is also essential in orthopedic and surgical applications, including bone grafts and joint repair, due to its structural properties. Additionally, collagen is incorporated into dietary supplements and protein powders to support joint health, improve skin quality, and strengthen hair and nails. Its biocompatibility and versatility make it a valuable material in regenerative medicine, such as in the development of artificial skin and tissue engineering.
