Thumbs up if you already know just how amazing hyaluronic acid is for your skin!

If you’re not convinced yet, read on.

The benefits of hyaluronic acid are almost too many to count, from intense hydration to skin plumping and firming, so we went searching for the best reasons to make HA part of your skin care regimen.

Dry skin NEEDS hyaluronic acid.

As it turns out, hyaluronic acid isn’t optional when it comes to dry, dehydrated skin. You probably know that hyaluronic acid can trap a lot of water, 1,000 times its weight as a matter of fact, but we didn’t really understand just how powerful this effect was until we looked at the numbers. By volume, 0.03 ounces of HA (about the size of a raindrop) can hold approximately 203 ounces of water, which is more than the average person needs to drink in two days, according to the USDA. That’s some serious hydration!
