What is Hyaluronic acid?

GoodCosmetic ingredients

Also known as: Hyaluronic Acid, Sodium Hyaluronate, HA

Short answer

Hyaluronic acid is a humectant that also occurs naturally in the skin. It binds many times its weight in water, making skin look plump and hydrated. It is safe and suits almost every skin type.

What is Hyaluronic acid and what does it do?

Hyaluronic acid is a molecule found naturally in the body; in cosmetics it is used as a moisturizer that draws and holds water in the upper skin layer. On labels it usually appears as 'Sodium Hyaluronate'.

Benefits

By binding water it makes skin look instantly plumper, smoother and more alive. It temporarily softens the look of fine lines. Since it contains no oil, it is comfortable even on oily and acne-prone skin.

What to watch for

In a very dry environment, if used alone without a moisturizer on top, it can pull water from deeper skin instead of the air and leave a dry feeling. The fix is simple: apply to damp skin and seal with a moisturizer on top.

How to use it

Apply a few drops of serum to slightly damp skin, then 'seal' with a moisturizer. It can be used morning and evening and is compatible with other actives.
