AHA vs BHA
AHA (Alpha Hydroxy Acids)vsBHA (Beta Hydroxy Acid)
AHAs exfoliate the skin surface for brightness and anti-aging, while BHA (salicylic acid) penetrates pores for acne and oil control. Both are chemical exfoliants.

| Solubility | Water-soluble | Oil-soluble |
| Targets | Skin surface, dead skin cells | Inside pores, sebum |
| Best Results | Texture, tone, fine lines, pigmentation | Acne, blackheads, oily skin |
