Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!
Learn more about WaterSodium Citrate is the sodium salts of citric acid. In skincare, it is used to alter pH levels and acts as a preservative.
Its main functions are to maintain the pH of a product and neutralize metal ions.
The acidity of our skin is maintained by our glands and skin biome; normal pH level of skin is slightly acidic (~4.75-5.5).
Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.
Learn more about Sodium CitrateCitric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

My favorite way to cleanse in the morning!
I have dry but acne prone skin, so I really wanted to find a way to cleanse my skin in the morning without also stripping my skin of every ounce of moisture it has. I’ve been testing micellar waters for awhile now, but so far this one by COSRX is my favorite! It feels a little more hydrating than some of the others I’ve tried (Bioderma and Garnier), and Show more
One if the best micellar/cleansing water I've tried, doesn't feel drying and won't irratate sensative skin, I have oily sensative skin and I'm also acne prone.
Only use it when you have makeup spf or when your skin is really oily otherwise just use your gel or foam cleanser. And this cleansing water is also !!fungal ance safe!! what more can you ask for.

It does a good job with makeup and sunscreen, however it struggles a little bit when removing waterproof mascara. But despite not fully removing it, if you let it sit for a minute it will loosen it up enough for the water-based cleanser to finish the job. I know you're not supposed to rinse a micellar water, but I've always felt better doing a second cleanse afterwards. I also like to let it rest Show more
One of my favorite cleansers!!
