AHA vs BHA, what’s the difference?

AHA vs BHA what’s the difference and why you should use them

You’ve heard all the tea about k-beauty buzzing everywhere. It’s affordable and trendy, but most importantly, it gives you that glowing radiant skin you’ve been desiring for so long. But it’s so easy to get lost with all the information available. We’ve made it clear and simple for you!

If it’s glowing skin you’re after, then exfoliating is one area you should focus your attention on. Your skin already goes through its own natural exfoliation process, the speed at which it does so deteriorates with age and lack of proper skincare.

You may be very tempted to use those gritty and harsh facial scrubs that are widely available on the market. But those can cause the reverse effect of glowing skin and potentially even damaging (especially to sensitive skin).

The exfoliating acids that can get you excellent results are BHA (beta hydroxy acid) and AHA (alpha hydroxy acid). These acids are often found together in skincare products as they both tackle different issues in their own unique way. You'll find them all over the skincare scene, but knowing exactly how best to use them can be a challenge.

AHA - Alpha Hydroxy Acid

AHA’s target a number of skin issues. The famous AHA that you have most likely already heard of is Glycolic acid, known for effectively exfoliating dead skin cells, revealing glowing radiant new skin. The exfoliating effect of AHA’s helps to target fine lines and wrinkles, they can also target the dermis to reduce pigmentation issues. AHA’s also have humectant properties making it a great option for those of you with dry skin.

This gentle exfoliant will help keeping your whiteheads under control. The liquid delivers vitamins and brightening agents to even out your skin and clean your pores. Perfect for sensitive and acne prone skin that need a little a glow-up treatment!


BHA - Beta Hydroxy Acid

BHA’s are oil-soluble, so while AHA’s work well on the epidermis of your skin, BHA’s also target deep pore exfoliation by entering the dermis for deep pore exfoliations. You most likely want to opt for BHA based products if you have oily skin/ combination skin or from clogged and visible pores. Salisylic acid is certainly the star of BHA’s, known as the main active ingredient in acne products, and now you know why!
