We're working on rolling out prepaid duties for more countries soon.
It turned out to be a clean finish and I'm very satisfied.
It was cheap and left my skin feeling refreshed after washing. It said to swirl it directly onto my skin if I wanted to wash thoroughly, so I tried it and it stung my eyes quite a bit. I guess I'm just bad at it...
I'm glad I used retinol, but if it gets in my eyes it stings like crazy. It removes makeup well, but it's better to remove point makeup. I wonder if this is the reason why it's less likely to cause acne, as my skin didn't get too rough. It's not bad, but I prefer purple retinol, so I probably won't buy it again.
Repeat purchase. I usually use a different face wash, but I use this one on days when I only need sunscreen and want to skip it. I apply it directly on days when I'm concerned about dirt, and lather it up on other days. The foam is thick and dense rather than fluffy, and it feels great when washing. I usually use a face wash with a scrub, so this one without is just right. My skin doesn't feel tight after washing.
The mascara is hard to remove, and if you use it mainly around your eyes it stings and is very painful, so I think I'll use it as a face wash.
