This extract also contains tannins and gallotanins that have antioxidant, soothing, anti-inflammatory, and anti-irritation roles.

Personal opinion about COSRX AHA/BHA Clarifying Treatment Toner

My first impression when holding this baby is that the design is highly pleasing to the eye, firmly held in hand, and the spray nozzle is convenient. Her texture is liquid, a little thicker than water but not as thick as a serum; the white substance is clear and slightly sour when taken out. I’m not sensitive to this scent, so I think it’s pretty good, but if you don’t like it, don’t worry; it almost leaves no smell after applying it on the skin for a few minutes.

I use it every day in the evening after cleansing with a cleanser; the texture is relatively light; after applying, it does not feel sticky or heavy, almost like that type of water, so it penetrates pretty well quickly on the skin.

The most obvious and fastest results when using this toner are the feeling that the skin is cleansed, the pores are unclogged, the facial skin feels smoother. After using for about one month, the condition of blackheads on both sides of the nose is reduced, pores also seem to be tight.

The most important thing is that it contains low concentrations of AHA and BHA, so it hardly pushes acne or fear of irritation like using other AHA or BHA exfoliating products. If you have never used these two ingredients products, you can still feel secure when using COSRX AHA/BHA Clarifying Treatment Toner.
