Ever feel like there’s a new beauty ingredient you can’t stop seeing and hearing about? That all of the sudden, it’s in every product and all over your Instagram feed? This is what our Beauty Buzzwords series is all about – helping you learn more about these mysterious ingredients and why everyone is raving about them.

For the second installment of Beauty Buzzwords, we’re diving into a powerful hydrating ingredient – hyaluronic acid.

What is it?

The word acid can definitely be a bit concerning when you’re talking about skin care, but hyaluronic acid (HA) is actually very gentle on skin and quite different from other skin care acids such are salicylic or lactic acid, which be harsh and drying.

HA is a sugar molecule that is naturally occurring in our bodies. Its role is to bind water and to lubricate flexible parts of the body, like joints and muscles. It has the incredible power to draw in and hold more than 1,000 times its own weight in moisture, thus making it an amazing hydrator and overall skin-health supporting ingredient.

The Science Behind HA

Here’s where things get a bit science-y; Hyaluronic Acid is a humectant, which means it attracts moisture from the air and preserves it in the skin, keeping things plump and hydrated. Because HA is a large sized molecule, it is too big to penetrate the skin and instead sits on top of the surface, where it binds to water to maintain moisture. What this means is that HA itself does not add hydration, but is very effective when paired with water or other ingredients at retaining moisture.

Some lab-made HA has been altered to include low-, medium- and high-molecular weights of HA and is therefore said to achieve “multi-depth hydration.” There are several kinds of HA:

  • Synthetic, which is produced in a lab by scientists
  • Natural, often extracted from rooster combs, and
  • Botanical (my personal favourite), also known as Cassia Angustifolia, which is found in Indian Senna Seeds

What are the benefits?

The main attraction of hyaluronic acid is of course its ability to lock in moisture by holding onto water so our skin can absorb it, but it also has amazing anti-aging benefits. Our ability to naturally create HA in our bodies declines with age, causing dryness and wrinkles, which HA can help to combat. Finally, HA support skin repair through its skin-calming and anti-inflammatory abilities, providing defense from UV damage.

Who should be using it?

I recommend hyaluronic acid for all skin types (dry to oily), and those who are looking to start adding some anti-aging products to their skin care routine. Bonus tip: Vitamin C and HA pair very well together and will pack a powerful punch when it comes to improving plumpness and fine lines.

How can you use it?

Although hyaluronic acid can be found in all types of skin care and beauty products, serums are one of the best methods to add HA to your routine. Apply as the first step after cleansing to damp skin, and follow up with an additional moisturizer.

    Derma-E has an excellent serum with hyaluronic acid which I have been using for years – it has made a significant improvement in my skin. Their daily moisturizers both day and night are excellent as well.

    Earth Science’s serum is great too! It has eliminated my dry patches, reduced lines, and it is completely scent free. I also like that HA is the third ingredient, meaning it’s in high concentration.
