If AHAs and BHAs feel too strong for your skin, PHAs are often described as the gentler option. Here is what they are and who they suit.
What is a PHA?
PHA stands for polyhydroxy acid, a type of gentle exfoliating acid often considered milder than AHAs or BHAs. PHAs help smooth the look of the surface while tending to feel less harsh, which makes them a common starting point for sensitive skin curious about exfoliation.
Who are PHAs good for?
PHAs suit people who find stronger exfoliating acids irritating, including many with sensitive-feeling skin. As with any exfoliant, start slowly, use them a couple of times a week at first, and always follow with hydration and daily SPF.
How do you use a PHA gently?
Introduce it slowly, avoid stacking it with other strong actives at first, and moisturize afterward. If skin feels tight or stingy, scale back. A comforting Rich Moist Soothing Cream helps skin feel calm after exfoliating, and our barrier guide covers overdoing it.
