#1
Best Overall Alternative

- Size: 39.9 ml
The why
A lightweight dimethicone gel with 21% glycerin, panthenol, and madecassoside for post-retinoid dryness, redness, and barrier distress. It suits oily or combination skin better than richer protectants, though rosacea-prone users report intense burning and some acne-prone users break out.
One minus
Breakouts happen, including reported fungal-acne flares
Good forDry Skin, Sensitive Skin
Both recommended for Redness / Irritation.
“It’s made a big difference for after outside days and after showering.”

#2
Best for Texture / Pores

Skin Perfecting 2% BHA Liquid Exfoliant
Paula's Choice·Exfoliant
See alternatives2% leave-on salicylic acid for clogged pores and acne
- Size: 118.3 ml
The why
A leave-on 2% salicylic acid exfoliant that stays in pores instead of rinsing away. Research supports salicylic acid for acne, while Redditors report impressive blackhead, sebaceous-filament, and texture results. Start slowly; daily use commonly triggers dryness, redness, peeling, or barrier damage.
One minus
Overuse wrecks the barrier with dryness, redness, and peeling
Good forOily Skin, Combination Skin
Both recommended for Hyperpigmentation.
“It did make my skin very soft and got rid of blackheads overnight. Got rid of the hyperpigmentation left by the acnee very fast, too (kinda ironic).”

#3
Best for Hyperpigmentation

The why
This thick 10% suspension targets acne, redness, and post-acne marks. Redditors report results with consistent use, and studies found azelaic acid clears acne better than placebo; dimethicone-heavy texture pills under makeup and can sting reactive skin.
One minus
Thick, grainy texture pills under makeup
Both recommended for Hyperpigmentation.
“Every night apply The Ordinary Azelaic Acid Suspension 10%”

#4
Best for Redness / Irritation

Paula's Choice·Acne Spot Treatment
See alternatives10% azelaic acid plus salicylic acid — two-active formula
- Size: 29.6 ml
The why
This 10% azelaic acid cream-gel also contains salicylic acid, giving Redditors a two-active approach to redness, breakouts, and marks. Studies support azelaic acid for acne, but reactive or dry skin may find the combination irritating and pilling under sunscreen frustrating.
One minus
Salicylic acid can trigger breakouts or irritation on reactive skin
Both recommended for Hyperpigmentation.
“my acne marks went away completely in a month”
