Montarbo Skincare Vitalizing Vitamin C Serum 12%

Vitalizing Vitamin C Serum 12%

Being the intelligent skin enthusiast that you are, I know that you've likely tried many Vitamin C products promising to "change your life," or at least your complexion. Promises, promises! Instead of trying to convince you that our product is the "best," I'll let you be the judge, since you will see the results for yourself in the mirror. As you may know, Vitamin C products can be extremely pricey, overrated, unstable and not very effective at repairing your skin's discoloration or dehydration. Stability is everything, my love. Our 12% Vitamin C serum contains L-Ascorbic Acid for optimal results, so you won't have to guess if it’s working or not. You’ll instantly feel it working by the slight heat and tingling sensation, which subsides in a few minutes. This is a sign of a stable, concentrated Vitamin C product. 1 oz/30 mL.
