AHA and BHA Skincare
Alpha-hydroxy acids (AHAs, such as glycolic and lactic acid) and beta-hydroxy acids (BHAs, primarily salicylic acid) are chemical exfoliants that remove dead skin cells from the surface — AHAs work on the skin's surface, while oil-soluble BHAs can penetrate into pores.
What AHAs & BHAs Help With
- Texture and dullness — AHAs resurface the skin's top layer
- Acne and congestion — BHAs (salicylic acid) exfoliate within pores
- Pigmentation — regular gentle exfoliation supports a more even tone
Frequently asked questions
What's the difference between AHA and BHA?
AHAs are water-soluble and work on the skin's surface; BHAs are oil-soluble and can penetrate into pores, making them useful for acne-prone and oily skin.
How often should I use an AHA or BHA?
Typically 2–3 times a week to start, since over-exfoliating can damage the skin barrier — frequency can be increased gradually as tolerance builds.
Can I use AHA/BHA with retinol?
They can be combined but often on alternating nights to reduce the risk of irritation, especially for those new to actives.
