COSRX AHA/BHA Clarifying Treatment Toner

0.1% BHA and 0.1% AHA at pH 3.8-4.5 in a mineral thermal water base. Gentle enough for daily use, effective for oily and congestion-prone skin.
A low-pH exfoliating toner (pH 3.8-4.5) with 0.1% betaine salicylate (BHA) and 0.1% glycolic acid (AHA). Gentler than dedicated exfoliating serums, which is why it fits in a daily toner step rather than a 2-3x-per-week step. Mineral-rich thermal spring water rather than deionized water as the base. For oily skin, congestion-prone skin, or blackhead concerns, 4-6 weeks of daily use produces visible pore-refinement results that humectant toners don't deliver. Do not use with retinol on the same night — alternate nights is the correct protocol.
Pros
- BHA + AHA at concentrations safe for daily use — not a 1-2x-per-week product
- Mineral thermal water base adds tolerability without the irritation of alcohol
- Clear visible results on congestion and pore appearance within 4-6 weeks
Cons
- Must not be used on the same night as retinol — requires routine planning discipline
- Not suitable for compromised, broken, or active eczema skin
