What is Hyaluronic Acid?

Hyaluronic acid, also known as sodium hyaluronate, is a humectant; it is a hydroscopic ingredient, meaning that it draws moisture in from its surroundings. Hyaluronic acid can retain over 1,000 times its weight in water within the cells of skin, making it a brilliant moisturiser. On average, the human body contains 15 grams of hyaluronic acid, one third of this gets synthesised on a daily basis; 50% of the remaining is found in connective tissues throughout our bodies, the other 50% can be found in the skin as hyaluronic acid it is a major component of the extracellular matrix. As we age our natural occurring amount of hyaluronic acid in the skin decreases, therefore it is great to have hyaluronic acid in a skincare routine to help plump dry, lacklustre skin.

What are the benefits of Hyaluronic Acid?

  • Improves skin hydration
  • Triggers collagenesis – the production of collagen
  • Fights free radicals
  • Helps to maintain the skins elasticity
  • Antibacterial and anti-inflammatory properties to help with wound healing

How does it work?

The hyaluronic acid molecules are too large to penetrate the dermis, which is where it is needed to help plump up fine lines and wrinkles. The hyaluronic acid sits on the skins surface and acts as a moisturiser, due to its humectant properties water is drawn into the skin from the surroundings, penetrating beneath the dermis, plumping up the skin, keeping it hydrated and supple. Hyaluronic acid is also an antioxidant; therefore, it helps to remove free radicals from the skins surface, preventing them from causing damage to the skin.
