Hyaluronic Acid Serum
Hyaluronic acid may not be the newest or flashiest ingredient out there, but it's tried and true and seriously good for your skin. First off, don't let the word “acid” fool you. Hyaluronic acid isn't harsh or skin-stripping at all. In fact, it's the exact opposite a powerful humectant (aka moisture-binding ingredient) that keeps skin plump and hydrated and, yes, young-looking.These products claim to dramatically improve the appearance of the skin and by doing so pander to the desire many of us have to find youth in a bottle.
In The Skin:
Picture your dermis, that layer if inner tissue beneath the surface (or epidermis) of your skin, as a sponge. The solid parts of that sponge are the collagen and elastin fibres that form the supporting matrix of the skin, and the spaces within the sponge are where the skin's gel-like hyaluronic acid sits. Obviously, if you can pack those spaces with more water-rich hyaluronic acid your skin will have a fuller, firmer, more youthful appearance. While you're never going to get back that perfectly dewy baby-skin, it is possible to help restore the skin's hyaluronic acid content and give grown-up skin a younger, fresher, more supple look.
