What is Hyaluronic Acid and Should I Use it in my Skincare Routine?

Posted on

Hyaluronic acid is most certainly a buzzword in the skincare community. If you’re a skincare newbie, anything with the word “acid” in it could leave you feeling a little uncertain, and you probably have some questions. To cut to the chase – hyaluronic acid is an effective and simple ingredient, easy to incorporate, and everyone can benefit from using it. In today’s piece, we’re going to take more of an in depth look at what this buzzworthy ingredient actually is, the potential benefits of using it topically in your skincare routine, and our favourite hyaluronic products.


So, what is Hyaluronic Acid?

Hyaluronic acid, sometimes referred to as Hyaluron or HA scientifically, is a naturally occurring element found in our bodies. Its purpose is to hold water and to help our skin stay hydrated. HA can regulate the levels of moisture within our skin and can hold up to one thousand times its own weight in water. Yes, really!  It helps keep our cells healthy and hydrated. However, as with a lot of the good stuff our body naturally produces, levels of hyaluronic acid reduce as we get older due to ageing and environmental damage. That’s where hyaluronic acid skincare comes in!

In skincare, there are generally three types of ingredient: humectants, emollients and occlusives. Hyaluronic acid is a humectant, meaning very basically it is an ingredient that keeps the skin hydrated because it draws moisture in and helps your skin retain that moisture. It penetrates the skin easily and generally works well with all skin types.


Why should I use Hyaluronic Acid?

It’s important to keep the skin hydrated for both health and appearance. If your skin is dehydrated it can increase the chance of premature skin sagging, fine lines, and cause a rough textured surface. Your skin may also be more easily irritated and sensitive. Hydrating the skin results in a smoother surface, a plump, healthy look, and better protection against external aggressors. It can help with preventative anti-ageing, as well as generally strengthening your skin. Because of hyaluronic acids ability to easily penetrate skin and draw moisture into the upper layer of skin cells, it is a reliable and effective option in helping hydrate the skin to achieve all the above.

Another great quality of hyaluronic acid is that all skin types can benefit from its use.  Hydration is a crucial step in any skincare routine and is not the same the as moisturising. Usually when we talk about moisturising, we’re talking about replenishing oil in our skin with a moisturising emollient or occlusive product. Whereas oily skin types may avoid adding more oil with moisturising, replenishing lost water and hydrating the skin is a separate treatment and vital for everyone. That’s why hyaluronic acid is a fantastic ingredient for all skin types to look for in an ingredients list. You really can’t go wrong with hydrating products and they play a central role in any Korean-inspired skincare routine.


Must-Have Products

Now that we have a clearer idea of what hyaluronic acid is and why we can all benefit from the humectant, we wanted to share our favourite hyaluronic products. All these must-haves are carefully formulated to ensure thorough hydration and retention of moisture for a youthful glow and healthy complexion. Exactly what we want!
