Abstract
The invention relates to a preparation for topical use, having light protection properties and in a special application form. In the known light protection agents containing the naturally occurring active compound melanin, the problem is inadequate transport of the melanin to its site of action. According to the invention, this problem is solved by a preparation for topical use which is characterised in that it contains melanin, dissolved or dispersed in one or more fluorocarbons, which are present as asymmetric lamellar phospholipid aggregates in an aqueous system together with a phospholipid, with a particle size of the aggregates in the range from 200 to 3000 nm.
