Chondroitin sulfate is widely used in the treatment of osteoarthritis to help reduce pain and improve joint function. It is often taken as a dietary supplement to support cartilage health and slow the progression of joint damage. Additionally, it is used in some eye drop formulations to relieve dry eye symptoms by promoting moisture retention on the ocular surface. In the cosmetic industry, it is incorporated into skincare products for its hydrating and anti-aging properties, helping to maintain skin elasticity and reduce the appearance of wrinkles. It is also explored in wound healing applications due to its ability to support tissue repair and regeneration.
