Collection: PHA Skincare | Gentle Korean Exfoliating Acids for Sensitive Skin

Exfoliate gently and hydrate sensitive skin with PHA skincare. PHAs (polyhydroxy acids) are the gentlest exfoliating acids, with larger molecules that work on the skin's surface to smooth texture and brighten while also drawing in moisture. Our curated collection of 25+ PHA toners, serums, pads and cleansers is perfect for sensitive, dry and reactive skin that can't tolerate stronger acids, leaving it smoother, brighter and hydrated without irritation.

Is PHA good for sensitive skin?

Yes. PHA has larger molecules that work more gently than AHA or BHA, making it perfect for sensitive, dry and reactive skin that can't tolerate stronger exfoliants.

What's the difference between PHA, AHA and BHA?

PHA is the gentlest and also hydrates, AHA exfoliates the surface for texture and dullness, and BHA works inside pores for oily, acne-prone skin. PHA is best for sensitivity.

How often can I use PHA?

PHA is gentle enough to use more often than AHA or BHA, and some formulas are suitable for daily use. Still, introduce it gradually and follow with moisturizer.

Can I use PHA with other exfoliants?

PHA can be layered carefully with other actives, but avoid over-exfoliating. If you already use AHA or BHA, alternate days and keep your routine hydrating and soothing.
