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

Best way to remove makeup EVER!! EASY, FAST, AND REFRESHING
Style: 16.7 fl oz
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!

Gentle makeup remover that works well
Style: 3.4 Fl Oz (Pack of 1)
I love this micellar water and really appreciate that it comes in a travel size. It’s gentle on the skin and works well for removing makeup without irritation.
It’s easy to use and convenient for trips or keeping in a bag. Overall, it’s a great cleanser that I would definitely use again.

Less issues
Size: 13.52 Fl Oz
I double cleanse. I find that mineral oil based makeup removers are hard to wash off. Oil based ones are nourishing and easier to remove but are all very dissimilar. I find formulations with active ingredient CAPRYLIC/CAPRIC GLYCERIDES high on the list are the best for my skin type. Combination/Oily(summer). RetinA/Retinoid , glycolic, Vitamin c user. These formulations emulsify everything. No scrubbing or excessive rubbing. No funny skin irritants or slimy film left on skin.
MY Favorites:
La Roche-Posay Micellar Cleansing Water for Sensitive Skin [all skins even those using actives]#1 My Favorite All year.
Black Opal Even True Skin Perfecting Cream Cleanser [Good for dry skin or winter time]Discontinued
Clarins Cleansing Milk with Gentian (Combination or Oily Skin)[A opaque 'milk' texture for Truly oily skin not drying but not hydrating]#2 Summers mostly. Pricey but worth it. Emulsifies everything and rinses well.
CeraVe Foaming Facial Cleanser | Makeup Remover and Daily Face Wash for Oily Skin |
Now Solutions Soothing rose facial cleansing oil[ Good for all skin types consistency is 'thin'ish'] #3 I like the texture its an oil but doesn't feel 'congested' greasy to me.
Sheamoisture Even Radiant raw honey 3n1 cleansing balm[Room temperature butter texture for dry and or dehydrated skin. Possibly good for skin needing nourishment(shea and honey). IMO this is a 'wipe off cleanser. Say with a 'wonder cloth' or some such. Not a daily use but has its place for sure. May work as a hydrating face mask. Think Estee Lauder Triple cream(discontinued). Nice size and affordable.
Cerave Makeup removing cleanser Balm[ A 'waxy' looking balm that seems whipped. All skin types]. Does what it says. IMO a wipe off cleanser even thought directions say rinse. I rinse then wipe then cleanse. Sometimes i just go directly to cleansing. Note no CAPRYLIC/CAPRICTRICERIDE or its derivatives in the ingredient list. This one took time for me to remove but its not greasy. Has other solvents, emollients and emulsifiers. Definitely a gentle skin conditioner. A good product.
