Description

The AHA/BHA Clarifying Treatment Toner is COSRX’s entry point into chemical exfoliation. Instead of a strong peel, it pairs small amounts of exfoliating acids with plant waters to create a light, everyday toner. COSRX designs it to gently remove dead skin cells, help keep pores looking clear and leave the surface of the skin smoother and softer. The brand presents it as suitable for people who are new to acids.

Key ingredients

  • Willow bark water and apple fruit water – the base of the formula, chosen for a gentle exfoliating effect.
  • Glycolic acid (AHA) – works on the surface of the skin for a smoother, softer feel.
  • Betaine salicylate (BHA-type) – associated with clearer-looking pores and balanced oiliness.

How to use

  1. After cleansing, apply the toner to a cotton pad.
  2. Gently wipe over the face, avoiding the eye and mouth area.
  3. Continue with the rest of your routine.
  4. For daytime use, finish with a broad-spectrum sunscreen of SPF 30 or higher.

Who it suits

COSRX says it suits all skin types, including sensitive skin, and it is especially useful for oily and combination skin with visible pores, occasional congestion or rough texture.

Good to know

COSRX advises not to use it together with other acids, retinoids or vitamin C, and to avoid it during pregnancy or breastfeeding. Because exfoliating acids can increase sun sensitivity, daily sunscreen matters. Patch test first: apply a small amount behind the ear or on the inner forearm for a few days and stop using the product if redness, itching or stinging appears. Avoid the eye area unless the product is designed for it, and speak with a pharmacist or dermatologist if you have a known skin condition or allergy.
