This is one of my favorite budget-friendly actives. The Ordinary’s Azelaic Acid really helps reduce post-acne marks, uneven skin tone, and redness. It’s a slightly silicone-y texture, but I don’t mind it — it actually smooths the skin well and works great under sunscreen or makeup.
I use it mainly in the morning, and it has definitely helped calm down my PIE (post-inflammatory erythema). No stinging or irritation, but I would recommend starting slowly if your skin is sensitive.
It’s not super hydrating, so pair it with a good moisturizer!
