AHA BHA PHA Serum Benefits: What Each Acid Does for Your Face

If you’ve often seen these labels on skincare, wondering what their difference is, and what each of them really do for your skin, you’re not alone. People often get weary of the word “chemical” in chemical exfoliation, but these chemical exfoliants: AHAs, BHAs and PHAs,  act as gentle exfoliants that dissolve the “glue” that bonds your dead skin to your skin cells. They are a more gentle alternative to harsh scrubs as they don’t tear at your skin’s surface.
