What Is Hyaluronic Acid and What Does It Do
Hyaluronic acid is a natural substance in your body. It is a type of sugar molecule called a polysaccharide. You find it in connective tissues, skin, eyes, and joint fluid.[1]
This molecule loves water. It can hold up to 1,000 times its weight in water. That makes it great at keeping things moist.[2][3]
In your skin, hyaluronic acid pulls in water from the air. It keeps the skin hydrated, plump, and smooth. It helps reduce dryness and fine lines from lack of moisture.[3][5]
Different sizes of hyaluronic acid work in different ways. Large molecules stay on the skin surface. They form a film to lock in moisture. Smaller ones sink deeper into the skin layers for longer hydration.[3]
In joints, it acts like a lubricant. It cushions bones and reduces friction. This helps with movement and eases stiffness in conditions like osteoarthritis.[1]
It also protects cells. Hyaluronic acid grabs harmful free radicals and chemicals. This shields tissues from damage.[1]
Doctors use it in medicine. Injections during eye surgery prevent dry eyes. It also treats joint pain.[1] In cosmetics, it is in creams and fillers. Fillers add volume to lips or cheeks. They feel natural and can be reversed if needed.[4]
Food makers add it to products for better texture and health perks. It supports joint health and skin from inside.[2]
Your body makes hyaluronic acid, but levels drop with age. That is why people use it in skincare and supplements.
