When it comes to skincare, we all have different needs. However, one thing we can all agree on is a desire for healthy, hydrated skin.

It’s no wonder then, that hyaluronic acid has been one of skincare’s buzziest ingredients for the last few years – and there are no signs of it dimming into the background. According to L’Oreal, Google search terms for ‘hyaluronic acid’ are currently 50% higher than this time last year.

But why is it so popular? Hyaluronic acid has the ability to hold 1,000 times its own weight in moisture. The naturally occurring substance sits on the skin’s surface and draws water into skin to keep it hydrated. Additionally, it assists the skin’s barrier to ensure it’s healthy and functioning properly.
