Amazing product for dry, mature skin.
Size: 4.98 Fl Oz (Pack of 1)
I’ve used Micellar water for years and this is a nice addition as it is very moisturizing, especially for mature skin (I also live in a very dry climate). Great for removing stubborn mascara and eye makeup.

Fabulous product for makeup removal
Size: 4.98 Fl Oz (Pack of 1)
I love this. I use a good squirt, massage into skin, including onto eyelids and lashes, then wet my hands, and massage into face further, which creates some suds. Then I use a disposable washcloth. I make it wet and wipe it all off. The makeup comes right off my face, including mascara, and my face feels soft and not dry at all afterwards. I’m on my second bottle.

Best cleaner

I continue to purchase this even though it’s pricy! Makes my skin feel so clean and doesn’t break me out.

Melts Makeup Off
Size: 4.98 Fl Oz (Pack of 1)
I love this stuff! It melts my makeup away so gently, even mascara, so I don’t have to scrub as hard as I used to with other cleaners. I follow with my face soap, and my face actually feels like everything has been wiped away now. I feel like my blackheads have even improved and my pores are less clogged.

Nice and work well for sensitive skin
Scent: Unscented, Size: 25 Count (Pack of 2)
Work well and don’t irritate my eyes or skin. Little pricey but I think it’s worth it— compared to Neutragena or others which burn my eyes and face !
