Can you use Salicylic Acid with Zinc PCA?

Safe to mix

Yes, it is safe.

There is no known chemical conflict between Salicylic Acid and Zinc PCA, and neither makes the other less effective. They share a goal (acne and oil control), so together they reinforce each other.

How to use them

Use them in the same routine morning or night. Apply Salicylic Acid first, then Zinc PCA, moving from thinnest to thickest texture. Finish with sunscreen in the morning.

What Salicylic Acid does

An oil-soluble beta-hydroxy acid that gets inside pores to dissolve the sebum and dead skin behind blackheads, whiteheads and breakouts. It is the go-to for oily, acne-prone skin.

What Zinc PCA does

Zinc salts help regulate sebum and have mild anti-inflammatory and antibacterial effects. That is why zinc so often appears next to niacinamide in oil-control serums.
