The invention relates to a skin lightening composition, more particularly a composition which derives synergy between an active of natural origin and an active of synthetic origin. The present inventors have judiciously combined a selective salt of a dicarboxylic acid viz. disodium fumarate along with a specific extract of a plant source e.g. Salvia officinalis rich in certain organic aromatic acids to provide for synergic skin lightening benefits. They have further found that inclusion of certain activity enhancers in the composition of the invention improves the skin lightening efficacy.
