Hyaluronic Acid + Chondroitin Sulfate provides BioCell Collagen, which naturally includes hydrolysed collagen type II, chondroitin sulfate and hyaluronic acid. Collagen type II is commonly linked with cartilage and joint support, chondroitin sulfate is often used for connective tissue and joint formulas, and hyaluronic acid is best known for hydration and lubrication support.
That is why this product is often used for both joints and skin. The joint side comes from collagen type II, chondroitin and hyaluronic acid working together in connective tissue support. The skin side comes mainly from hyaluronic acid and collagen, which are both widely used in beauty formulas. It is a useful choice if you want those ingredients in one product rather than buying them separately.
