Best AHA Buys

AHA stands for alpha hydroxy acid, which is the name of a type of exfoliating acid that works to dissolve the bonds that hold dead cells onto the surface of skin, making it appear dull and lacklustre. The two most commonly used AHAs are glycolic and lactic. Glycolic is a really small molecule and this means it’s wonderful for refining and smoothing skin because it gets right in there and it’s also good for targeting hyperpigmentation. Lactic acid is a much bigger molecule, so while it’s still working to dissolve the bonds that keep dead skin cells clinging on, it’s less penetrative. It’s great if you’re new to acids or if your skin is sensitive. Lactic acid is also a humectant, which means it binds to water, so helps to keep skin hydrated as well as exfoliated. The world of AHAs can be quite a daunting one as there are a lot of options, but below we’ve picked out five of our favourites.
