It’s one of the most hydrating ingredients, but if misused, hyaluronic acid can actually dry out your skin.

There’s no doubt about the efficacy of hyaluronic acid; hailed as a skincare hero by experts and dermatologists alike, it’s a humectant (meaning it helps reduce the loss of moisture) that can hold up to 1000x its own weight in water.

“It’s a water-holding gel with the ability to hold 1000 times its own weight in moisture. When it’s applied topically, skin acts as a highly-effective barrier and those hyaluronic acid molecules are too big to squeeze through the dermis (the layer of skin beneath the epidermis), which is where it needs to be to help plump lines and wrinkles.” - Dr Sam Bunting

So instead, it sits on the skin’s surface and acts as a moisturiser through its humectant (water-attracting) properties.

“That means it draws water into skin to keep it hydrated, supple and makes sure it keeps it functioning effectively as a barrier,” says Dr Bunting.

You can use it as often as you like. We recommend applying it twice per day, once in the morning and once at night.
