#2
Best Cheaper Alternative
- Size: 29.6 ml
- Price per ml: $0.23/ml (original $0.40/ml)
The why
A 2% leave-on BHA serum for oily, clog-prone skin and stubborn blackheads. Redditors use it as a maintenance exfoliant, and studies back the acne-clearing angle. Dry skin and irritated barriers usually hate it.
One minus
Can sting, dry out, and wreck a weak barrier
Both recommended for Texture / Pores.
“I do this only on my nose where I struggle with blackheads and sebaceous filaments.”

Best for Acne
Daily Care Acne Pads With Salicylic Acid, Maximum Strength
Stridex·Acne Spot Treatment
See alternatives2% salicylic acid in an easy swipe pad
The why
A no-rinse 2% salicylic acid pad that Redditors keep using for blackheads, clogged pores, KP, and random breakouts. Studies back the acne angle, but the community also treats it as a harsh, drying swipe, especially on already irritated skin.
One minus
Can feel harsh and stripping fast
Good forOily Skin
Both recommended for Acne.
“For the face stuff maybe add a gentle BHA like stridex pads couple times a week - they're pretty cheap and help with blackheads and comedones.”
— Reddit, r/SkincareAddiction
#4
Best for Texture / Pores
- Size: 29.6 ml
- Price per ml: $1.42/ml (original $0.40/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 Hyperpigmentation.
“Paula’s choice azelaic acid tremendously helped reduce breakouts and redness for me.”
