Not irritating
The vitamin C 23 brightens the skin and helps with skin dark spots. This vitamin C has an oily silky consistency which I love it feels really great on the skin. It has no scent and it doesn't irritate the skin at all but it does leave a sticky feeling after it's dries but after you layer another skin Care product it goes away. So for me this one is best to use after a toner and before Serums.
