Cosrx Low pH Niacinamide Micellar Cleansing Water- The best cleaning water?

  • By Vickie Le

Published: Saturday, October 18, 2025

If I recall well, Cosrx introduced its first cleansing water at the same time as I needed one, so I purchased it. I was debating between this and the Torriden one, but I decided to go with COSRX Low pH Niacinamide Micellar Cleansing Water 400ml as it was less expensive on Tiktok than others like the Garnier Micellar Cleansing Water 400ml.

Thankfully, it did not let me down!
Now that I'm nearly halfway through the bottle, these are my thoughts:
In addition to gently removing sunscreen and pollutants, this low pH micellar cleansing water with niacinamide and zinc can also help control excessive sebum production and moisturize the skin. For anyone wondering what is micellar cleansing water, it’s a gentle yet effective formula that uses micelles to lift dirt, makeup, and oil without drying the skin.

 

PACKAGING

It is packaged in a simple yet robust circular plastic bottle with a label that is both detachable and recyclable. Its pop-open top makes it simple to dispense the product.

 

TEXTURE

The COSRX Low pH Niacinamide Micellar Cleansing Water 400ml is extremely hydrating and leaves the skin feeling neither oily nor sticky. The ideal surface for it is a cotton pad. In addition to hydrating and mattifying your skin, it will aid in the gentle removal of any impurities. After using this cleansing water, my skin feels cleaner, more moisturized, and clearer. Despite its ability to regulate sebum, it doesn't feel tight or drying at all.

 

SCENT

It has no scent and no fragrance.

 

APPLICATION

Use a cotton pad soaked in enough water to gently clean your entire skin until all of the sunscreen and contaminants have been removed. For areas with heavy or waterproof makeup, you can leave the pad on your skin for ten seconds or more.

Although it is not necessary, it is strongly advised to rinse with water or follow with the COSRX Low pH Good Morning Cleanser for a double-cleansing routine that ensures a thoroughly clean and refreshed complexion.

 

INGREDIENTS

Water, Dipropylene Glycol, Polyglyceryl-4 Caprate, Panthenol, Sodium Hyaluronate, Allantoin, Niacinamide(1,000ppm), Zinc PCA, Madecassoside, Propanediol, Caprylyl Glycol, Ethylhexylglycerin, 1,2-Hexanediol, Sodium Citrate, Citric Acid, Disodium EDTA

 

EFFICACY

With minimal rubbing, this has effectively eliminated any signs of sunscreen, pollutants, debris, and oil from my skin. Even when the micellar cleansing water is left on the face without being washed off, it doesn't feel dry or irritating at all. Actually, after using it, my skin feels clean, hydrated, and renewed. My personal preference is to avoid leaving any surfactant on my skin, thus after using cleansing water, I always rinse with water or use a second cleanser like the COSRX Low pH Good Morning Cleanser.

 

END THOUGHT

This water is excellent for cleansing, in my opinion. I have tried over ten cleansing waters in the last few years, and this one is definitely among the finest. It’s even better than others I’ve tested in my My Beauty Diary Micellar Cleansing Water review experience. The COSRX Low pH Niacinamide Micellar Cleansing Water 400ml is definitely worth repurchasing!
