It’s naturally found in the body and necessary for maintaining smooth, plump skin. Thanks to research and advancements in cosmetic dermatology, hyaluronic acid—available in supplement, cream and injectable form—is a mainstay in the war against aging. Because hyaluronic acid binds to and absorbs water, it a gives a fullness and plumpness to the skin that we are constantly trying to replicate as the effects of aging intrude. When there are ample amounts of hyaluronic acid in the skin, it is plump and smooth with good support.
What it is: Hyaluronic acid is actually a sugar that attracts water molecules to provide a plump, spongy effect to skin.
How it plumps: As water is absorbed by the acid, volume is created, acting in the same manner as how a sponge soaks up water and becomes full to even out every crevice. When the skin is young, the amount of hyaluronic acid in the body is abundant, which is why the skin has a nice plump look to it.
When levels drop: As hyaluronic acid levels drop and the body begins to produce less of it, the effects give way to skin that can look crepey, dry and laden with lines and wrinkles, with an overall lack of support.
An aged appearance: “A deficiency of hyaluronic acid, coupled with the effects of aging, can really give way to an aged appearance and make you look older than you may be,” says New York dermatologist Roy G. Geronemus, MD.
