Benefits of Hyaluronic Acid For Your Skin

Written by Roisin Mc Dermott , Educator and Dermal Therapist for the Australasian Academy of Cosmetic Dermal Science

Recently some of the most popular of the cosmetic skincare brands have started to include Hyaluronic acid in their formulations, meaning that no matter your budget, you can have this in your routine. This is a good thing, of course, but you should know when to use it, when not to use it and which types of hyaluronic acid (HA) do what.

In the simplest of terms, hyaluronic acid is an ingredient that pulls moisture to it. The term is known as “humectant”. Humectants are a key type of hydrating ingredient that you will find in almost most skincare products – glycerine is a humectant. Hyaluronic acid can bind more than 1000x its weight in water to it. When many see the word “acid”, they think exfoliating acid. Hyaluronic acid is not an exfoliating acid so it’s not going to help you to slough off dead skin cells.

Hyaluronic Acid and the skin

Hyaluronic acid is a natural ingredient in the sense that it naturally exists in the skin already. Hyaluronic acid is made throughout the body and in the dermis, and it is part of several processes when it comes to the skin – obviously, it’s important for hydration but it is also involved with wound healing (tissue repair). As we age, our rate of HA production decreases and decreases so our skin struggles to hydrate itself as easily as it used to. Therefore, it’s considered to be an anti-ageing ingredient, even though it’s beneficial for all ages.

Hyaluronic Acid for skin: what does it do?

Topical hyaluronic acid, due to its moisture-pulling capabilities, can give the skin back moisture. Realistically, if your skin is not at peak health (ie. you’re not using a routine that replenishes your barrier, protects your skin from pollution and light-related damage, you’re not getting enough omegas internally etc.), your skin may not be holding enough of its own moisture. If you’ve got the right type of hyaluronic acid in a serum, it can penetrate the skin and hydrate it at lower layers which is something that moisturisers can’t do due to the size of their molecules.

Other forms of hyaluronic acid can plump up the uppermost layers of the skin, giving you the gift of instant youth.
Therefore, it is known for its use in fillers! It also works as an antioxidant to protect your skin from the free radical damage that can age the skin faster.

Forms of hyaluronic acid in skincare

As I said, we can pop down to our local supermarkets and get something with hyaluronic acid in it. However, there are different forms that do different things, and some may be considered more beneficial than others.

  • High molecular weight hyaluronic acid – the molecules of HMW hyaluronic acid are larger so they do a great job of sitting in the uppermost layers of the skin and swelling it but you won’t be getting moisture drawn deeper into the skin... This will be listed on products as hyaluronic acid
  • Low molecular weight hyaluronic acid – this is hyaluronic acid (HMW hyaluronic acid) whose molecules have been made into fragments that penetrate into the skin easier due to their smaller size… better penetration means it can get deeper into the epidermis – often, when a product says it has low molecular weight HA, it's sodium hyaluronate (explained below)
  • Sodium hyaluronate – sodium hyaluronate is the salt of hyaluronic acid that has the same humectant capabilities but can have a smaller molecular size, so like with low molecular weight HA, it can penetrate the skin deeper. Ultraceuticals B serum contains Sodium Hyluronate. This can be purchased at aspire student clinic.
  • Cross-linked hyaluronic acid – cross-linked hyaluronic acid can remain on the skin for longer as it is more resistant to the hyaluronic-gobbling enzyme found in our skin (hyaluronidase)… its effects are longer-lasting.

What skins are best suited to hyaluronic acid?

Dehydrated Skin

As it is a hydration-blaster, it immediately eliminates dehydration.

Oily & congestion-prone skin

As a non-oily hydrator, it does wonders as a hydrating product for those with oily or spot-prone skin as it doesn’t clog pores and doesn’t leave a greasy layer on the skin.

Mature skin

Hyaluronic acid, specifically high molecular weight hyaluronic acid, gives mature skin back the bounce and elasticity it may have lost naturally. Moisture slightly swells the uppermost layers of the skin so fine lines and wrinkles will look instantaneously less noticeable.

Where to purchase hyaluronic acid containing products

If you like to know more about products containing HA, speak to one of our students at Aspire studying the Advanced Diploma of Cosmetic Dermal Science, Graduate Diploma of Dermal Science or Graduate Diploma of Cosmetic Nursing and Injectables.
