Amazon C.
Super potent and good

This was recommended to me by a top dermatologist and I was beginning my skin care journey with Vit C with this serum. It’s pretty potent and effective and I can see the difference just in a few days

This stuff is magic in a cleared up my skin a great bit. I still have a few spots to go but it is clearin up. It does have a smell but it’s goes away went u rub it in to ur face, a small amount goes a long way

Very hydrating and leaves my skin so smooth

Yes! There is a smell BUT I think that’s normal with vit C especially it’s highly concentrated. I used 2 months of Medicube and I don’t know if my dark spots improved maybe a little. I like this Cosrx, very hydrating, leaves my skin smooth same as medicube but this one is way better affordable which is a plus and 23% vit C while medicube only 14% I guess. Will see for a few months if my dark spots lessen or improve. More updates soon. Highly recommend
