What’s hyaluronic acid?

Hyaluronic acid is a naturally occurring glycosaminoglycan found throughout the body’s connective tissue and joints. Glycosaminoglycans are simply long unbranched carbohydrates, or sugars, called polysaccharides.  This naturally occurring substance works to help retain the much-needed moisture, but as we get older the levels tend to deplete which can lead to dullness and loss of elasticity along with fine lines and wrinkles.

Hyaluronic acid is the main component of what gives your skin structure, and is responsible for that plump and hydrated look. Found in a whole load of products, its primary function is restoring and retaining moisture and is suitable for all skin types, including those with sensitive, acne-prone skin.

Hyaluronic Acid isn’t just a fad ingredient,

but a staple for your skin care routine.

What are the benefits of hyaluronic acid?

Why’s hyaluronic acid so magical? For starters, hyaluronic acid can bind up to 1000 times its weight in water! In other words, it functions as a humectant and holds water molecules onto the surface of your skin to keep it nice and hydrated.

Anytime we’re talking about skin that’s well-moisturised, we’re mainly referring to skin that has a lot of water content. Perhaps you’ve heard the term transepidermal water loss, or TEWL for short? This is the scientific term for the measurement of how much water is evaporated from the skin.

When a product prevents TEWL, that means it’s keeping your skin hydrated by making sure that water doesn’t escape from your skin’s surface. Hyaluronic acid does exactly that by slowing the rate at which the water evaporates.

Apart from being a very effective hydrator, a couple of studies have also found that it’s very good for healing wounds, too!

What it is and how it affects your skin?

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.

Why could hyaluronic acid dry the skin out?

If you’re applying hyaluronic acid to a very dry face, it can actually end up drawing moisture from the deeper levels of your skin, which in turn will cause more harm than good and leave your complexion feeling tight and uncomfortable.

It’s a problem that usually occurs when humidity levels are extremely low – meaning there’s a lack of moisture in the air.
