Pick your answers and the shelf shows only what fits.
Two percent salicylic acid in a short-list, leave-on liquid, sold by the maker to unclog pores and control oil. It has a long record and a tacky finish some owners cannot stand.
Skip it if you hate a sticky finish; owners call this one tacky
A big bottle of seven percent glycolic acid for rough texture and dullness. The maker warns it off sensitive or peeling skin, and the burning reviews suggest it means that.
Skip it if your skin is sensitive or peeling; the maker says not to use it
A mild AHA and BHA toner in a spray bottle, sold by the maker to beginners for daily use. Too gentle to do much for some, and it still breaks out others.
Skip it if you want a strong exfoliant; some owners see no effect on blackheads
Salicylic acid 2% on a textured pad, labeled by the maker as an acne medication and free of alcohol. The list does have fragrance, menthol and ammonium lauryl sulfate, and owners split on burn and dryness.

The well-known glycolic toner at five percent, with aloe and witch hazel. Fragrance and dye are on the list, and the scent is what its unhappy owners mention first.
Skip it if fragrance bothers you; owners call this one overpowering
