For everyone dealing with dry skin, hyaluronic acid is the ingredient you should be looking at when buying skin care products. Hyaluronic acid is naturally present in the human body. It is found in the connective and neural tissue, joints and of course the skin.
We use it for skin care mainly because it`s ability to retain water and to moisturize the skin. It can hold up to 1000 times the amount of water in relation to it`s own weight. Because the hyaluronic molecule is pretty large it does not absorb into the skin but stays on the surface and supplies it with water. Beneath the layer of hyaluronic acid the skin plumps up and the wrinkles become less visible. Along with the hydrating effect the hyaluronic acid also possesses healing powers and calms irritated skin.
Hyaluronic acid can be applied on the skin with a toner, serum or cream. In that case it will act as a moisturizer. If you want to use it for anti-aging purposes, it will have to be injected underneath the skin. Hyaluronic acid found in the deeper layers of skin activates the synthesis of collagen and increases the presence of retinoic acid, which ads to the moisturizing from within. But by all means don`t fall for the supplements that contain hyaluronic acid, cause they just don`t work.
To recap, hyaluronic acid is a wonderful ingredient, which will moisturize and plump up your skin. It is suitable for dry and oily skin. It also helps with wounds, scar tissue and acne. Because the molecule is large it will not penetrate into the skin, it will only sit on top of it and keep it moist. It will not work as an anti-aging ingredient (if you want that, you need to visit your doctor and he will inject it).
