What’s the purpose of hyaluronic acid in skincare?

Skincare enthusiasts will be well aware of hyaluronic acid, the holy grail of ingredients for dehydrated skin. However, those new to the term may be intimidated by the idea of putting acid on our skin. So what exactly is hyaluronic acid? And why is it in so many products?


What is hyaluronic acid?



A key component of many skincare products, hyaluronic acid is a humectant, a molecule that retains moisture. It has the unique ability to hold 1000x its weight in water, making it somewhat of a dream for skin that needs hydration.


Hyaluronic acid is a gel-like substance that our bodies naturally produce to keep our skin soft. It’s also present in our eyes, joints and connective tissue. However, as we age, our bodies produce less hyaluronic acid, meaning our skin becomes less plump and hydrated, which is part of the reason that fine lines and wrinkles begin to appear.


While the hyaluronic acid found in the body is created naturally, the version you’ll come across in skincare products is synthetically created. Those concerned about using acid on the skin will be reassured to know that hyaluronic acid falls somewhere between 5.0 and 8.0 on the pH scale, compared to our skin’s pH level, which is usually between 4.5 and 6.2, which means the two are a good match. 


What is the best way to use hyaluronic acid?



As with most skincare products, you’ll reap the benefits of hyaluronic acid with consistent use. Remember that hyaluronic acid will draw moisture from wherever it can find it, meaning that if the air is dry, it’ll pull moisture from the deep layers of your skin, so apply hyaluronic acid on slightly damp skin. In doing so, the molecules will be able to cling to the moisture on the surface of your skin, which will allow the ingredient to work its hydrating wonders.


Which hyaluronic acid-containing product should I use?



When it comes to hyaluronic acid, there are different molecular sizes, and your skin will absorb them differently. 


Long-chain hyaluronic acid does not penetrate the skin but forms a film that has an anti-inflammatory effect. However, as soon as you wash your face, the film will disappear, meaning this type of hyaluronic acid doesn’t have a long-term impact.


Short-chain hyaluronic acid penetrates the skin deeply, making the skin plumper and reducing wrinkles. Thus, it has a lasting effect.


Look for a product that combines long-chain and short-chain hyaluronic-acid to benefit from the effects of both types.
