Chondroitin sulfate is widely used in the treatment of osteoarthritis, where it helps to reduce pain and improve joint function by promoting cartilage repair and inhibiting enzymes that break down cartilage. It is often taken as a dietary supplement, either alone or in combination with glucosamine, to support joint health and slow the progression of joint degeneration. Additionally, it is used in eye drops to treat dry eye syndrome, providing lubrication and reducing inflammation. In cosmetics, chondroitin sulfate is incorporated into skincare products for its moisturizing and anti-aging properties, helping to maintain skin elasticity and hydration. It is also utilized in wound healing formulations to enhance tissue regeneration and reduce inflammation.
