So firstly, what do the letters mean? AHA means alpha hydroxy acid and BHA means beta hydroxy acid. Now that we have that covered, what is the difference apart from the name and which one should you choose for your skin?
They are both exfoliants but they work best for different skin types & the level of absorption on the skin differs between the two. AHAs work best on normal to dry skin and are limited primarily to work on the skins surface whereas BHA works best on normal to oily skin and goes that next step further, working on the pores in addition to the skins surface. Both of them will improve your skins firmness, will help to smooth out lines & wrinkles & will give your skin that hydration boost.
If you're particularly looking to reduce the signs of sun damage, we would recommend you go with an AHA. If you're looking to reduce the number of blemishes you have, we would recommend you go with a BHA. Because BHA works on your pores too, it helps to unclog them and reduce the size of them so you're left with clean & glowing skin.
The other thing to remember is that neither will feel like your typical exfoliant. They work over time and basically unclog everything and breakdown dull, dry skin which then allows your skin to shed and ta da! Beautiful, glowing skin.
If you're undecided on which one to try, you can always go for a product with both. We'd recommend you start off slow though and would suggest using around a product with 2% of either or, then from there build up to higher percentages or a mixed product.
So to sum up all of the above, here are our top 3 products (1 x AHA, 1 x BHA and 1 combination of the 2)!
Now you can enjoy smooth, glowing skin as much as we do :)
