ABSTRACT:
A method of increasing pigmentation in mammalian skin, as well as protecting mammalian skin against ultraviolet damage, is disclosed. Also disclosed is a method of increasing pigmentation in mammalian cells, as well as a method of enhancing melanin production in mammalian melanocytes. A preparation useful in the present methods is additionally disclosed. The methods comprise administering to the epidermis or to the cells DNA fragments, either single- or double-stranded, or a mixture of both, or deoxynucleotides, in a liposomal preparation or other appropriate vehicle. The preparation includes DNA fragments or deoxynucleotides and an appropriate delivery vehicle, such as liposomes.
