My Personal Experience with COSRX AHA/BHA Clarifying Treatment Toner on Sensitive Skin

As a skincare enthusiast with particularly sensitive skin, I approached the COSRX AHA/BHA Clarifying Treatment Toner with a mix of excitement and caution. AHA and BHA are renowned for their exfoliating properties, but they can be a gamble for sensitive skin types like mine. Here’s my in-depth, review based on my personal experience.

What is AHA/BHA?

Alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs) are chemical exfoliants that help to gently dissolve dead skin cells. Chemical exfoliation is different from physical exfoliation, which uses physical objects (such as scrubs) to manually remove dead skin cells.

What does the product do:

Formulated with natural AHA and BHA, this toner helps to gently exfoliate and remove dead skin cells while also helping to minimize the appearance of pores and regulate excess oil production. The botanical extracts in this toner help to nourish and hydrate the skin, leaving it feeling soft and refreshed


Water, Salix Alba (Willow) Bark Water, Pyrus Malus (Apple) Fruit Water, Butylene Glycol, 1,2-Hexanediol, Sodium Lactate, Glycolic Acid, Betaine Salicylate, Allantoin, Panthenol, Ethyl Hexanediol.

Initial Impressions:

The COSRX AHA/BHA toner comes in a sleek, simple bottle. I liked the straightforward packaging, as it focuses on function over frills. It’s minimalist and functional, with a clear label that spells out its key ingredients: AHAs and BHAs, though I was initially wary of how my sensitive skin would react to the active ingredients. It’s minimalist and functional, with a clear label that spells out its key ingredients: AHAs and BHAs. I appreciate this transparency because it helps me understand what I’m putting on my skin.

How to use:

After cleansing, spray the toner onto a cotton pad and gently wipe onto the face, avoiding the eye and mouth area.

For use during the daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater.

Application Experience:

The toner comes in a spray bottle, which I found quite convenient. It has a fine mist application, ensuring that the product is evenly applied in my face. However, I was a bit skeptical about how effective a spray toner could be, but this one proved to be quite efficient.

After double cleansing (of course!) I applied this and there’s a slight tingling sensation, which is typical for AHA/BHA products. It’s not uncomfortable, but it’s something to be aware of, especially if you have sensitive skin. The toner feels refreshing and light, and it gets absorbed quickly without leaving any sticky residue.

Results Over Time:

I’ve been using this toner for a month now, and I’ve noticed some changes. Thank God it suits my sensitive skin! I was very skeptical and scared that it might cause horrible breakout but my skin texture has improved – it feels smoother, and my pores appear slightly smaller. The combination of AHA and BHA works well to exfoliate the skin, getting rid of dead skin cells and unclogging pores. However, it might purge skin sometime.

I don’t have redness that much so couldn’t tell the difference. I also noticed my breakouts are minimal now. My skin is prone to occasional acne, and since adding this toner into my routine, the breakouts have been less severe and more manageable. Am I being delusional or my skin looks a bit brighter now?

Skin Compatibility:

My skin is combination type, and I find this toner to be quite balancing. It doesn’t dry out my skin, thanks to its hydrating ingredients, yet it effectively controls oil in my T-zone. However, I would advise caution for those with extremely sensitive skin, given the active ingredients.

Final Thoughts for Sensitive Skin Users:

For those with sensitive skin like myself, the COSRX AHA/BHA Clarifying Treatment Toner can be a beneficial addition to your skincare routine, provided you use it judiciously. It’s crucial to listen to your skin and adjust usage accordingly – less can indeed be more. A patch test and gradual introduction are also advisable.

Would I recommend it? Definitely, especially if you’re dealing with texture issues or looking for a gentle exfoliator that can be used daily. It’s a well-formulated product that delivers results, and it’s earned a permanent spot in my skincare routine. But always do patch test first!
