When you’re looking at skincare product labels, you might have noticed something called alpha hydroxy acids, otherwise known as AHAs. While you probably trust the skincare company enough to go with its ingredient choices, it never hurts to know exactly what you’re dealing with. Here’s the lowdown on AHAs and why you should use them.

According to Allure Magazine, AHAs weaken the fluid bonds that keep skin cells on the surface of your body stuck together, allowing dead skin cells to come off easier. As we age, these fluid bonds get thicker (kind of like glue), meaning the cell turnover process becomes slower and dead cells stick around for longer, dulling our complexions.

So, if you use AHAs, you should end up with more radiant skin that’s not bogged down by dead skin cells. There are many fine anti-aging products on the market, like PETER THOMAS ROTH – Glycolic Acid 10% Hydrating Gel, that use AHAs to deliver you results. They’re also useful in acne treatment products.
