Hyaluronic Acid is a glycosaminoglycan, which is a fancy name for a vital naturally-occurring substance that’s part of your skin’s youth supporting matrix. It works to keep every aspect of your skin stable and constantly renewed.
This is one of the most important ingredients in skincare at the moment. It works to hydrate your skin thoroughly and is known for its “unique capacity to bind and retain water molecules,” as referred to by Dr, Justine Kluk, Consultant Dermatologist.
Beauty and the Geeks says, "In a sense, hyaluronic acid acts like a sponge holding vast amounts of water in the skin, effectively plumping out the skin and by doing so it can reduce the appearance of fine lines and wrinkles, as well as improving the skin's hydration and texture of the skin."
What is a humectant?
Hyaluronic Acid is known as a humectant. It’s mentioned a lot in skincare as a description for certain ingredients.
Chemically humectants are hygroscopic substances that form hydrogen bonds with water molecules. This bonding helps moisturise the skin by drawing water from the lower cell layers.
It works by pulling water from the dermis (the second layer of skin) to the epidermis (the top layer of skin). This process increases the level of moisture in the stratum corneum (the layer of dead cells that comprise the outermost crust of the epidermis). They also encourage the shedding of dead cells by breaking down the proteins that hold the cells together. If the humidity is over 70%, humectants can even draw water vapour from the air to help moisturise your skin.
They’re great for all different skin types because of this ability. It doesn’t add oil to oily skin and pumps moisture into dry skin. So it might be time for you to include a humectant into your skincare. Especially Hyaluronic Acid, try the following products;
