Brighten + Firm 15% Vitamin C Serum

The THD Ascorbate really is gentle—no stinging like my old serum, yet my dark spots have visibly lightened after three weeks. Paired with the peptides, my skin feels firmer and looks brighter, which is honestly more than I expected from one bottle.

I’ve tried a lot of vitamin C serums that sting or pill, but this one with THD Ascorbate goes on smooth and hasn’t irritated my skin once. The peptide combo has my face feeling noticeably firmer around my jawline, and a few sun spots have faded to the point I almost forgot they were there.

Three weeks in and my dark spots are visibly lighter — the THD ascorbate really is gentler than the straight vitamin C I used before, no stinging at all. I also like that the peptide blend makes it feel like I'm getting two steps in one every morning.
