AHA/BHA Clarifying Treatment Toner

COSRX AHA/BHA Clarifying Treatment Toner puts two families of acid into one easy daily step. COSRX combines AHA and BHA with purifying botanicals, so it lifts away build-up and adds a little hydration back at the same time — which is why the brand aims it at people just starting out with chemical exfoliation.

What it actually does

• Refines texture on the surface. The AHA side loosens dull, dead cells, which COSRX links to smoother, softer skin and a livelier look overall.
• Clears congested pores. The BHA element handles the blocked, bumpy areas and helps keep pores looking tidier.
• Keeps oil steadier. COSRX lists more balanced sebum production among the results.
• Exfoliates and hydrates together. The brand's point of difference here is doing both in a single pass instead of leaving skin stripped.
• Deliberately gentle. It is described as soft daily exfoliation suitable across skin types, sensitive skin included.

How to use

1. Cleanse, then decant onto cotton. Spray the toner onto a cotton pad rather than straight onto your face.
2. Sweep gently. Wipe across the face, staying clear of the eyes and lips.
3. Follow with the rest of your routine. Serum and moisturiser go on after.
4. SPF 30 or higher in the morning. COSRX asks for a broad-spectrum sunscreen on any day you use it.

Keep apart from: other AHAs and BHAs, retinol and vitamin C in the same routine. COSRX also advises against use during pregnancy or while breastfeeding.

Questions

Can I use this with my vitamin C serum?

COSRX advises keeping it away from vitamin C, retinol and other acids. Alternate them on different days or at opposite ends of the day.

Is it harsh on sensitive skin?

The brand lists all skin types including sensitive among its targets, and frames the exfoliation as gentle. A patch test on the jaw for a few nights is still the sensible route.

Do I need sunscreen with it?

Yes. For morning use, COSRX asks for a broad-spectrum sunscreen rated SPF 30 or above afterwards.
