Hyaluronic acid plays a critical role in the production of collagen, the most abundant protein in the body. Collagen’s main function is to sustain tendons, skin and cartilage. It provides integrity, firmness and elasticity to their structures. Maximizing collagen levels will keep skin supple.  Because of this, maintaining  body levels of hyaluronic acid is not only desirable for keeping moisture levels up, but also to keep collagen synthesis up, helping to provide an anti-aging effect on skin, as it remains supple and resistant to wrinkles and fine lines.
