"A youthful appearance is not only related to the absence of wrinkles but also to skin radiance and an even skin tone. Many cosmetic ingredients are used to lighten skin by the inhibition of tyrosinase, the rate-limiting enzyme in melanin formation. Flavonoids, as major constituents of the human diet, have many well-known beneficial qualities. The aim of this study was to find the ideal composition of flavonoids from various citrus extracts for an effective skin lightening cosmetic ingredient. A chosen blend of citrus extracts was tested for safety and in vitro efficacy. No cytotoxic effects up to 0.8mg/ml could be detected and inhibition of human tyrosinase was 60% at 0.4mg/ml. The blend of citrus extracts was liposomal-encapsulated, incorporated into a cosmetic formulation at 1%, and then tested for stability and skin irritation capacity, as well as eye irritation and mutagenic potential and exhibited a very good safety profile. Finally the product was studied in vivo on Caucasian skin for efficacy during 56 days and showed marked skin brightening effects at a concentration of 1% (0.4mg/ml). This liposomal-encapsulated citrus flavonoid blend is effective at 1% in a cosmetic formulation to fade age spots and brighten skin tone."
