Hyaluronic acid is basically the tried-and-true skincare equivalent of drinking eight glasses of water a day. But what is it actually? Let’s break it down: Hyaluronic acid, otherwise known as HA, is a naturally occurring compound in our body with skin-nourishing and skin-moisturizing superpowers. As Dr. Barbara Sturm (the creator of the cult-favorite hyaluronic serum in every celebrity’s medicine cabinet) says, HA “helps retain over 1000 times its weight in water, so it provides an intense moisture boost.” In other words, apply it topically and bam! Dewy, hydrated skin that looks and feels plumped to perfection.
