AHA stands for alpha-hydroxy acid and this consists of glycolic acid, lactic acid, and mandelic acid. These exfoliate the skin and stimulate collagen production. These acids are water-soluble and dissolve dirt on the surface of the skin. Because they work more superficially, they help with sun damage and aging skin. They promote hydration by bringing the water level back to the surface of the skin.
BHA stands for beta-hydroxy acid and this consists of salicylic acid. This type of acid is great for treating breakouts as they help unclog pores. It is oil-soluble which goes into our pores and removes debris and dead skin cells. Although it also works on the surface of the skin, it is known to work on a deeper level. One of its top benefits is smoothing skin, leading to that “glow” that everyone looks for.
There are benefits to both and they can be used together or separately. If you want to use them separately, I recommend using BHA’s in the morning and AHA’s in the evening. If you have any questions about these acids or want to start incorporating them into your routine, please reach out! I can be easily contacted via my website, social media, and by phone.
