ABSTRACT:
The present invention relates to a composition and method for skin depigmentation comprising the steps of encapsulating an effective amount of a water-soluble melanin inhibiting compound with a liposome, suspending the encapsulated melanin inhibiting compound within a topical vehicle, topically applying to the epidermis of the skin the suspended and encapsulated melanin inhibiting compound whereby the liposomes are transdermally delivered to the basal cell region of the epidermis causing interference with the biochemical synthesis of melanin in situ and subsequent depigmentation of the skin.
