Collagen is widely used in the cosmetic and skincare industry for its ability to improve skin elasticity, hydration, and overall appearance. It is a key ingredient in anti-aging creams, serums, and masks, helping to reduce wrinkles and fine lines. In the medical field, collagen is utilized in wound care products, such as dressings and grafts, to promote tissue repair and regeneration. It is also a common component in dietary supplements aimed at supporting joint health, reducing pain, and improving mobility, as well as benefiting hair and nails. Additionally, collagen is employed in the food industry as a gelling agent in products like gelatin desserts, marshmallows, and certain dairy items, enhancing texture and stability, and serving as a protein source in health drinks.
