11. Hyaluronic Acid
This element is included in most skin care products to help reduce the different signs of aging. The human body makes hyaluronic acid, and it keeps tissues lubricated and cushioned. It’s found in joint fluid, skin, and connective tissues. However, age, smoking, and sometimes, an unhealthy diet may cause a person to produce less of it as time passes.
Products containing this hyaluronic acid might help smooth down the skin. It works particularly well when pooled with vitamin C products.
