Garnier Targeted Vitamin C Anti Dark Spot Night Serum (£14)
In terms of a high potency, budget option, this is up there with some of the best I have tried. Because vitamin C is an antioxidant, when used during the day, it will continually protect your skin from environmental factors such as UV rays and pollution. When used as part of your evening routine, the 10 percent pure vitamin C has the chance to get to work on pigmentation and dark spots to even skin tone and texture.
