Samuel P.★★★★★
I’ve been using this vitamin C serum every morning for three weeks and my skin tone looks noticeably more even, especially around my cheeks where I had some dull patches. It’s a hydrating formula too, so I don’t need a separate moisturizer underneath, which saves me time in my routine.
Julian★★★★★
The 10% THD Ascorbate in this serum absorbs cleanly without that sticky feeling I usually get from vitamin C, and my skin has a dewy glow by mid-morning. It's been two weeks and my complexion looks more even overall, though I'm still waiting on the deeper pigmentation.
Robert★★★★★
My dark spots have visibly faded after three weeks of daily use, and the 10% THD Ascorbate doesn’t sting or pill under moisturizer. It’s thin enough to layer before sunscreen, which is exactly what I needed.
