READ MORE
The 2% salicylic acid is the formula’s real efficacy driver and is an evidence-backed concentration for unclogging pores and treating acne; the presence of sodium hydroxide suggests pH adjustment, but the published product information does not disclose the final pH, so optimal BHA activity cannot be confirmed. Humectants and 1% hyaluronic acid support hydration, while Zinc PCA may modestly support oil control, but the formula contains no retinoid, azelaic acid, or other strong complementary treatment active. The result is a solid but not clinically optimal formula: effective for acne and congestion when used consistently, with efficacy limited by the single-primary-active design and unknown pH.
