Use my code BRIDGETMIX for 20% off I have been using the vitamin c serum for about 2.5 months now and the coq10 for about 3 weeks. I’m very consistent with it. It feels AMAZING and the powder form keeps it fresh so you can activate it with the serum rescinds before it goes on your face. It’s my favorite product that’s made the most impact for my dark spots and melisma. LTKBeauty
