The claim for the intensive brightening elixir: "Unique BeautiControl technology targets surface cells damaged by hormonal, environmental and age-related factors to reduce the appearance of hyperpigmentation and age spots, while our exclusive Tri-C Complex? delivers three potent forms of vitamin C deep into the epidermis for healthy-looking, glowing skin!" It is $26 so not too pricey. They also have some other products in that line.
