Go to cleanser that’s simple, effective, and skin-friendly!
Style: 8.4 Fl Oz (Pack of 1)
I love this micellar water. It removes my makeup on the first pass with no harsh rubbing or irritation. Even around the eyes, it feels soothing rather than stinging, which isn’t always the case with makeup removers. It’s also fragrance free and lightweight, so it doesn’t leave behind any greasy or sticky residue.
Another major plus is the no-rinse formula. You can use it quickly with a cotton pad and be done, which makes it perfect for busy nights or when you just don’t feel like doing a full routine! It leaves your skin feeling clean, calm, and moisturized. Seriously gentle yet effective.

Gentle but removes makeup really well
Style: 16.7 fl oz
I really like this micellar water. I used to use a different brand, but I feel like this one does a better job removing my makeup while still being gentle on my skin.
I have sensitive skin with rosacea, and I wear liner, mascara, and eyeshadow daily. This removes everything from my eyes without needing a lot of rubbing or effort, which I really appreciate.
After using it, my skin feels very clean but also soft, not stripped or dry.
Overall, this has become my favorite micellar water and I’ll definitely keep repurchasing it.

Love this stuff!
Style: 3.4 Fl Oz (Pack of 1)
Literally the only micellar water that does not break me out. I have cystic acne prone skin, and my skin loves this stuff! Very gentle on the eyes and skin as a whole, while getting the makeup and dirt off well!

Bioderma Makeup remover
Style: 16.7 fl oz, Style: 16.7 fl oz
I like this product — the gentle formula cleanses, hydrates, and protects my face well. I usually use it in the morning before putting on makeup rather than at night. I gave it 4 stars because the top/cap comes off easily. Other than that that works well for my skin

This WORKS!!! My skin feels nice and clean after using this brand of micellar water! It is pro level!!! Way better than those make up remover wipes (which I had used for years) until I found this gem! No rinsing needed!
