Understanding the difference between AHA and BHA helps you choose the right exfoliant—especially if you need an exfoliant for sensitive skin. In AHA skincare, AHAs refine texture on the surface, while PHA chemical exfoliation (like Gluconolactone) supports hydration and barrier comfort, making it a smart fit for sensitive and pregnancy-safe routines.
What are AHAs?
AHAs are water-soluble acids that exfoliate the skin’s surface by loosening bonds between dead cells. They’re commonly used to improve dullness and texture.
What are BHAs?
BHAs are oil-soluble and can penetrate into pores, often used for oily or congestion-prone skin. Some sensitive skin types find BHAs more irritating depending on formulation.
Why PHAs are different
PHAs exfoliate more gradually and provide hydration support. Gluconolactone is known for gentle resurfacing plus barrier-friendly benefits.
Where POLISH fits in
