Good gentle foaming cleanser, not stripping at all
Size Name: 8 Fl Oz (Pack of 1), Style Name: Facial Cleanser
I use this to wash my face at night. It’s a really gentle foaming cleanser, doesn’t irritate my sensitive rosacea prone skin at all. Affordable and fragrance free. Highly recommended.

Lacking authenticity
Size Name: 8 Fl Oz (Pack of 1), Style Name: Facial Cleanser
The product came without: a) a box b) product seal around the opening - so anyone can tamper with it c) no manufacturing date d) no expiry date Facial wash? Or detergent? It's anyone's guess.

The pads have changed but still a good product
I have been using these make up remover pads for many years now and will continue to use them. I like the 3 pack so that I do not run out. I usually only use 1 pad a day so a 3pk will last me for a long while. I do not have any issues with the pads drying out in the time frame from opening them to using the last one so that is a major plus. I have no issues with these on my skin or that close to my eyes and they do a great job of removing my mascara, which is the only make up I use. I recommend them. I will say that in 2025 they have changed the material for their pads, they are now thinner and do not have the texture they used to have which for me the only difference is that they can be a bit more difficult to separate but nothing to complain about.
