Rated 5 out of 5 by from Lovely serum [This review was collected as part of a promotion.] My skin has reactivated to most vitamin c serums that I have tried. I use C-Tetra daily and so far have had no reaction whatsoever. It sinks into my skin very quickly and I continue to put the rest of my morning skincare over the top.

Rated 5 out of 5 by from Great vitamin c [This review was collected as part of a promotion.] An excellent vitamin c serum that sinks in easily and actually feels lovely on the skin. I find other brands to be gritty or oily but the consistency of this is perfect.
