TL;DR — Reddit consensus
Exfoliating toner with AHA/BHA that makes skin noticeably smooth and clears chest acne. Not for sensitive skin, and some see no dramatic results.
Amazon vs Reddit
Amazon loves it. Reddit isn't sold.
On Amazon: ★4.5 from 4,171 reviews — that's roughly 88% positive.
On Reddit: 60% of 18 redditors recommend it.
The gap of 27 points is unusual and worth reading the cons before you buy.

I say it on everyone one of these posts. If you are not sensitive, the Cosrx AHA BHA PHA LHA 35 peel is elite. It’s a strong mix of glycolic, lactic, and other acid
