COSRX Refresh AHA/BHA Vitamin C Daily Toner ingredients: is it worth it?
Decent gentle-toner concept, but the acids and vitamin C are likely too weakly dosed to be more than a mild skin-refresher.

The formula uses fruit waters (apple, willow bark) plus low-listed glycolic acid, betaine salicylate, and ascorbyl glucoside, which almost certainly sit at low percentages and at a non-aggressive pH, so you’ll get subtle smoothing and brightening over time but nowhere near the impact of a dedicated AHA/BHA or vitamin C serum; niacinamide, humectants, and soothing agents help skin tolerance and justify a moderate (not high) efficacy score.
