As a redhead I’ve got some pretty reactive skin, but vitamin C is a must. I’ve tried vitamin C serums with regular ascorbic acid but they were too harsh and irritating, even using once a week. This serum contains a stabilized form of vitamin C that is so gentle I can use it daily without any problems. When I run out, I can immediately tell a difference! My skin loves this stuff. I hope they never Show more
This works really well for me. It feels like a bit sticky at first but it absorbs well. You only have to use a little bit otherwise it can be a bit drying; I have sensitive and eczema prone skin.
