Using both? Safe to mix There is no known chemical conflict between Tretinoin and Zinc PCA, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other. How to layer them →
Tretinoin in short
The prescription-strength retinoid, and the gold standard for acne and photo-ageing, with decades of evidence. It works directly (no conversion needed), so it is stronger and more irritating than retinol or retinal.
Zinc PCA in short
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.
