What is hyaluronic acid and what can it do for your skin? 

Written by Vanessa Gibbs
Published on

Hyaluronic acid may sound intimidating, but it’s a natural molecule our bodies produce that attracts and retains moisture. This makes it a powerful ingredient for keeping skin hydrated, plump, and healthy. You might already be using it without realising - it’s found in serums, moisturisers, masks, injectables, and even supplements.

Because of its moisture-boosting properties, it’s a key ingredient in products that are designed to be moisturising. And it can often be found in anti-ageing and complexion-boosting products too. 

At Face Dr, our team of experts have decades of experience working with clients to get the glowing, healthy skin we all dream of. This means we know a thing or two about the best ingredients out there and what they do. Looking for free expert advice now? Why not book a free video consultation?

What is hyaluronic acid?

First up, what even is hyaluronic acid? Unlike other acids you may be used to, hyaluronic acid doesn’t exfoliate dead skin cells or act as a peel. In fact, it’s a sugar that our bodies make to hold onto water. It can be found in our joints and eyes, but most of it is in our skin. 

Hyaluronic acid keeps these things lubricated and moisturised, so when it comes to the skin, it’s a key factor in how things look on the surface as well as the health underneath. 

Over time, as we age, our levels of hyaluronic acid fall. UV rays also affect this, so—as with everything skincare related—it’s important to avoid excess sun exposure and to wear sunscreen daily to keep your hyaluronic acid levels high.

Less hyaluronic acid means less moisture in the skin. This causes all sorts of skincare concerns like dullness, dryness, wrinkles and fine lines. 


How does hyaluronic acid work? 


Luckily, scientists have figured out a way to top up our hyaluronic acid stores. The acid you’ll find in skincare products is a synthetic version of what our bodies make, but it’s a powerful ingredient that does the same thing. 

It can hold huge amounts of moisture—up to 1,000 times its weight, in fact. It draws in this moisture from outside of the skin to boost hydration levels on the surface.

What does hyaluronic acid do for the skin?


So what exactly do these moisture-boosting benefits mean for you? On the surface, hyaluronic acid has a range of results, including: 

  • Plumping the skin
  • Reducing fine lines and wrinkles 
  • Promoting a dewy glow  
  • Moisturising dry skin 
  • Boosting elasticity 
  • Smoothing out rough patches  
  • Reducing any tight sensations from dry skin  

Plus, it does all of this without a heavy or oily feeling. It’s a relatively lightweight product that even those with oily skin can use. 


Should I start using hyaluronic acid?

Everyone can see results from hyaluronic acid, but it’s especially beneficial for those of us with dry and dehydrated skin. Mature skin can also experience huge benefits as natural hyaluronic acid levels are lower. 

But, products with hyaluronic acid can also be used by those with normal to combination skin, as we all lose moisture and can do so from a hydration boost now and again. It’s even been shown to be safe for those with sensitive and acne-prone skin. 

 

Are there any side effects of hyaluronic acid?


As hyaluronic acid is something that the body naturally produces itself, side effects are very rare. But, as with any new product, it’s always a good idea to do a patch test first and check for any signs of irritation or reaction.
