COSRX AHA/BHA Clarifying Treatment Toner is an exfoliating toner with AHA’s and BHA’s. BHAs are oil soluble. They not only work on the skin’s surface, but also penetrate deeper and unclog pores and treat blemishes. This is why BHAs are preferred for those with normal to oily and clogged skin. BHAs have natural skin-calming properties, as well as anti-inflammatory and antibacterial activities and therefore can benefit those prone to redness and rosacea.
AHAs are humectants, meaning they can retain moisture, hence they are preferred for dry and damaged skin. AHAs are derived from natural substances. Combining these two forms of exfoliating will help to target blemishes without overdrying the skin.
- People with an Aspirin will react poorly to the BHA in this product (betaine salicylate). Avoid using this product if you have an Aspirin allergy.
