Most effective vitamin C
This is the product I let myself splurge on because I haven't found anything that compares so far. This is so fast-acting for lightening my dark spots/acne scars. I use one pump on the whole face, once a day in the AM so the bottle tends to last me about 3 months. Highly, highly recommend for dark spots!
Did nothing for my dark spots, instead destroyed my skin barrier.
