System Verdict
Lean, effective, and brutally simple: this is a well-formulated 2% salicylic acid exfoliant that does its core job very well. The efficacy score is driven by a real 2% salicylic acid leave-on active in a strong position, plus a minimal support base that should keep the formula elegant; the presence of sodium hydroxide indicates pH adjustment, which is important for BHA activity, while the green tea is a modest supporting antioxidant rather than the main driver. It does not earn a higher score because the formula is intentionally sparse, so there are no substantial barrier-repair or multi-active benefits beyond exfoliation and pore clearing.
