I first discovered the COSRX brand by browsing Youtube videos about skincare. Countless Youtubers were recommending the brand, and it took me only a second to look it up and find a product I could use. Cosrx AHA/BHA Clarifying Treatment Toner is a toner with hydrating, refreshing, and pH-balancing properties. It won me over, and I immediately ordered one online.

The Cosrx brand

Cosrx is a South Korean beauty brand founded in 2013. The brand takes its name from the word “cosmetics” and the symbol “RX” (denoting “prescription”) to affirm its commitment to creating effective, affordable, and skin-friendly products. Cosrx uses ten years of experience to continuously deliver functional, ingredient-rich cosmetics.
COSRX is known for its short ingredient lists, which feature high-quality and effective extracts and compounds that help trouble-prone, dry, dehydrated, aging, and sensitive skin.

COSRX also provides products that specifically treat acne problems. Do you need a serum*? Cleanser*? Pimple patch? Blemish cream? COSRX has them all, and they do fight acne!

Cosrx AHA/BHA Clarifying Treatment Toner claims

This treatment toner boasts our fave power hitters and other natural ingredients to help exfoliate and purify the skin.
The AHA/BHA Clarifying Treatment Toner is made to hydrate and rejuvenate the skin while preventing whiteheads, blackheads, and blemishes for the perfect flawless skin you deserve.

Who is this AHA/BHA toner for?

As often with Cosrx, this treatment toner is suitable for all skin types (without alcohol, perfumes, parabens, artificial colors, or phthalates) and recommended for acne-prone skin with imperfections. 

It’s essential to know what skin type you have when considering chemical exfoliants. This toner has mild ingredients, but you can never be too safe regarding your skin! If you have sensitive skin, you should test it out on a small patch of skin before committing to adding it to your regime.

Ingredients Analysis

As with almost all skin care products from the Cosrx brand, the ingredients list is minimalist.

AHAs and BHAs (Alpha Hydroxy Acid and Beta Hydroxy Acid) are chemical exfoliants that can dissolve and shed off a layer of dead skin and leave you with brighter and more revitalized skin. They work just like physical exfoliants but without the risk of scratching your skin.

If you already have sensitized skin, I advise you not to use this product daily and remember to apply sunscreen!

AHAs are found throughout nature in sugarcane (glycolic acid), sour milk (lactic acid), fermented grapes (tartaric acid), bitter almonds (mandelic), and fruits (citric acid and malic acid).

Cosrx AHA/BHA Clarifying Treatment Toner contains glycolic acid (0.1%). Glycolic acid is water-soluble. It helps dissolve the outer layers of the skin, which can bring closed comedones to the surface (I had some that were overgrown with skin and looked like tiny warts). AHAs treat acne, scars, melasma, hyperpigmentation, roughness, age spots, and seborrhea. They work by dissolving the outer layers and uncovering newer skin layers.

AHAs are moisturizing, and they also help with fine lines. After all, it’s uncovering younger-looking skin.

AHAs make you photosensitive, so your skin can end up worse, not better, if you don’t wear a good sunscreen.

AHAs come to act on the surface only and therefore eliminate dead skin cells but also provide hydration, stimulation of collagen production (anti-aging effect), and improve and brighten your skin tone. AHAs will act on the hyper-pigmented areas of your skin (such as sun spots or acne scars). It is not a whitening ingredient! I do not seek skin whitening but a more even complexion!

Betaine Salicylate combines salicylic acid – BHA and a gentle moisturizer, betaine.

BHA (0.1%) helps with inflammation and acne. BHAs are oil-soluble, so they can get into your sebum-clogged pores and help clear them out. This is why they can help “‘prevent” breakouts by keeping the pores clear and stopping them from forming clogs.

The BHAs will penetrate the skin and allow deep cleaning of the pores with an anti-inflammatory effect. This active ingredient acts to reduce pimples and blackheads. 

Salix Alba (Willox) Bark Water contains flavonoids, a polyphenolic compound with anti-inflammatory, regenerating, soothing, antiseptic, and anti-aging effects.

Cosrx AHA/BHA Clarifying Treatment Toner is enriched with 10% Pyrus malus or apple water. The water provides a gentle exfoliation to remove dead surface skin cells and excess oil while prepping the skin for nourishment and treatment from other skincare products. It has a balancing and refreshing effect.

Cosrx AHA/BHA Clarifying Treatment Toner does not contain niacinamide, hyaluronic acid, parabens, alcohol, essential oils, fragrance, or allergens. It is vegan and cruelty-free.

Packaging

As you can see, Cosrx AHA/BHA Clarifying Treatment Toner comes in a 150ml transparent plastic spray bottle. The toner has a very minimalistic design, nothing fancy. COSRX is a brand that pays more attention to its products’ ingredients than the packaging. The bottle is straight-to-the-point and straightforward with what kind of product it is.
This is a very unassuming-looking product, but what matters is what’s inside and how it works.

The nozzle distributes the liquid evenly and smoothly. It is misty enough to be sprayed directly onto the face. Since it is an acid toner, I prefer to apply it with my hands to avoid the eye area. It’s efficient, and less product is wasted on cotton pads. I enjoy this type of application; it’s hygienic and convenient.
It’s semi-travel friendly: it helps that it comes in a plastic bottle, but the large size does not.

Since you only need a couple of sprays of toner, one bottle of Cosrx AHA/BHA Clarifying Treatment Toner can last up to six months, so you are getting your money’s worth and more.

Scent

Since it is a chemical exfoliant, I expected a pungent smell. I was surprised to discover that it has a very mild scent that most acid products seem to have.
I like that it is fragrance-free and that the scent dissipates within seconds.

Texture

The product is watery and transparent. At first glance, you would think that it’s just plain water!
When you apply it, it practically disappears into your skin like water.
I use my clean hands to gently tap the product on my face for even distribution and better absorption.
Compared to other harsh toners, I can feel my skin becoming hydrated right after using my cleanser. It does not leave any sticky or filmy residue.

My thoughts on Cosrx AHA/BHA Clarifying Treatment Toner

Everybody has skincare horror stories. Maybe you once burned your skin by using a product you didn’t know you were allergic to, or perhaps you accidentally used foot cream instead of face cream? Both are equally terrifying.

Here’s my skincare horror story: I read something online about using coffee grounds as a facial scrub. I was a naïve young lady who longed for clear, smooth skin at the time. I was willing to try out almost anything that would help with my acne.

 So, after making my morning coffee, I directly applied the coffee grounds to my face.

No, I did not mix it with anything. Without doing more research, I thought exfoliating my face with the coffee grounds would be a good idea.

To cut my skincare horror story short, the coffee grounds were too harsh for my skin, they tore my skin, and I ended up with acne all over my face the next day. When I say all over, I mean all over. It was terrible!

I always considered coffee my true love, but it betrayed me! Needless to say, I found it hard to trust exfoliants again after that horrible experience.

However, two years ago, I was informed of the existence of chemical exfoliants. Hearing the word “chemical” terrified me initially, but I learned my lesson and researched them extensively. I was determined to find the perfect chemical exfoliant for my skin!

Behold… COSRX’s AHA/BHA Clarifying Treatment toner!

For reference, I have combination skin type with dehydrated, dry patches. I was not paid for this review or received it as a gift.

Honestly, I was pretty disappointed with this product during the first week I used it. I didn’t see any changes, even though I used it twice daily like I was supposed to. Regardless, I kept using it.

After about three weeks, I started seeing subtle but definite improvements in my skin’s texture (especially on one area of my cheek with tiny bumps). After around five weeks of using this product, I loved it!

This product takes some time to see results, but it is worth waiting for. It works.

As my acne cleared up, I decided only to use the Cosrx AHA/BHA Clarifying Treatment Toner at night. Even after two years of using it, I’m still scared of burning my skin (flashback to my skincare horror story), so when I’m going out, I make sure to use sunscreen cream with SPF 30 or more.

Cosrx AHA/BHA Clarifying Treatment Toner retains its effectiveness even if used once a day. My pores are never clogged now. I was confused and thought it was just a trick of my mind, but my suspicions were confirmed upon further inspection. My pores are reduced in size and appear cleaner. It is due to the anti-inflammatory properties of the BHA.

My skin is the clearest it has ever been, compared to when I was in college when I had a new pimple every week. The only time my skin breaks out is when I’m on my period, which is unfortunately unavoidable. Cosrx AHA BHA Clarifying Treatment Toner has helped reduce breakouts.

I have used many acne treatment toners and found that most leave my face dry and tight. They are usually very harsh and even burn sometimes. This toner is extremely gentle and does not irritate my skin at all. I was very pleasantly surprised.
The moisturizing effects are apparent, too, leaving my skin feeling supple and fresh.

As for the anti-wrinkle effects, I haven’t noticed anything drastic, which was expected as I’m still not at the age to develop them. But I hope it’ll have some preventative uses.

How do you use Cosrx AHA/BHA Clarifying Treatment Toner?

You may be wondering where something like this fits into your routine.

1. Clean and dry your face and neck;
2. Spray liberally onto clean hands;
3. Gently massage all over the face and neck;
4. Pat for better absorption;
5. Proceed with hydrating toners;
6. Serum(s);
7. Ampoule;
8. Moisturizer;
9. Sunscreen (if in the AM, of course).

If you prefer cotton pads, spray the liquid on a cotton pad and gently wipe it on your face. You can saturate the cotton pads and use them as a mask sheet to boost the effect of the toner.

Overall

Cosrx AHA/BHA Clarifying Treatment Toner is a miracle toner.
I trust COSRX and this toner, so I will continue using it to maintain my clear skin. It has noticeably reduced my acne scars until they’re no longer visible, and I don’t have to worry about my pores being clogged. My cheeks are usually the dry parts of my face, and since using this toner, they haven’t felt flaky or dry. For once, my skin looks healthy.

As always, you do you, be kind to your skin and yourself! Remember that every person’s skin and skin type is different, so what might work for me might not work for you, and vice versa. So before adding a new product to your skincare routine, it pays to do a little research first.

Pay special attention to ingredients that you might react to. Doing a patch test is always a good idea. Unsure? Best to consult your dermatologist.

Happy skin experimenting, and don’t forget the sunscreen!
