- Elegant light-serum texture
#2
Same Active: Azelaic Acid
- Key actives: Azelaic Acid 10%
- Size: 29.6 ml
The why
A leave-on azelaic acid booster with salicylic acid, licorice root, allantoin, and bisabolol. Redditors use it for redness, acne, and post-acne marks; studies back azelaic acid for acne, but the extra exfoliant makes sensitive or reactive skin yelp.
One minus
Salicylic acid makes reactive skin complain
Both recommended for Redness / Irritation.
#3
Best for Redness / Irritation
- Key actives: Sulfur 10%
The why
A 10% sulfur ointment you use short-contact as a mask or spot treatment. Redditors reach for it on acne, fungal acne, and rosacea flares, and the study backs acne improvement. Dryness and irritation are the catch.
One minus
Dries skin out fast
Good forOily Skin
“The De La Cruz mask is cheap & great but has a strong smell.”
