Hyaluronic Acid

What it is: A natural glycosaminoglycan that lubricates joints, hydrates skin, and supports connective tissue. Levels decline with age.

What it does: Expect joint lubrication and pain reduction (especially knees and shoulders), plumper and more hydrated skin, faster healing of soft tissue, and improved range of motion.

How it's used: Intra-articular injection for joints, subcutaneous or topical for skin.
