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.

great for acne-prone and sensitive skin
Size: 13.52 Fl Oz
Simply the best makeup remover I have found for my sensitive skin and acne-prone. I use it to take my makeup off before Cerave cleanser for a super gentle double-cleanse, and it has significantly reduced my cystic acne breakouts.
