You’ve seen it on the labels of your serums and moisturizers, and you’re not really sure what it is, but you’re confident it’s going to give you the dewy skin of your dreams. Today, we’re talking hyaluronic acid.
What is hyaluronic acid?
Hyaluronic acid is a natural polysaccharide or sugar molecule found in the human body, acting as a cushioning and lubrication agent for joints, nerves, skin, and eyes. As we age, our skin’s ability to retain moisture decreases and adding hyaluronic acid in your skincare routine can give your skin that extra boost. Hyaluronic acid first came into vogue as a dermal filler. It began to replace collagen as the filler of choice for several reasons. Hyaluronic acid was less likely to cause a reaction, lasted longer than collagen fillers, and if you didn’t like the results, it could be easily dissolved using the enzyme hyaluronidase.
Hyaluronic acid in skincare
Hyaluronic acid is great at plumping and moisturizing the skin because of its ability to carry up to 1,000 times its weight in water. However, it has a high molecular weight which means the molecules were too large to penetrate the skin’s surface. The results were limited.
Now with scientific advancements, hyaluronic acid can be found with a lower molecular weight, allowing it to penetrate the skin. Hyaluronic acid can temporarily plump and moisturize the skin. You might have also seen sodium hyaluronate on ingredient labels. This is a salt derived from hyaluronic acid that’s more easily absorbed and with all the advantages of hyaluronic acid.Sodium hyaluronate is pretty common and is actually a key ingredient in our Day Cream with Hyaluronic Acid and Argan Oil and our Revitalizing Serum with Hyaluronic Acid and Argan Oil.
