- Size: 29.9 ml
The why
Studies found azelaic acid helps acne, and Redditors say this 10% serum is especially good for redness, breakouts, and post-acne marks. It’s lightweight and calming, though some people get stinging, dryness, or a weak response.
One minus
Can sting or burn on a compromised barrier
Good forSensitive Skin, Combination Skin, Oily Skin
Both recommended for Acne.
#3
Best for Texture / Pores
- Size: 50 ml

A niacinamide-based spicule treatment that sits before serum and moisturizer, aiming for smoother texture and brighter tone. Redditors like the glow and faster absorption, and studies back niacinamide for acne, but irritation, stinging, and barrier damage are the dealbreakers.

Both recommended for Texture / Pores.
