ABSTRACT:
A novel lipomelanin sunscreen complex includes melanin linked to a lipid to form a lipomelanin. One or more ultra-violet-light absorbing compounds can be added to form a lipomelanin sunscreen complex. A method for making the complex includes the oxidization of DOPA in the presence of a lipid and one or more ultra-violet absorbing compounds to form a mixture and precipitating the complex from the mixture by the addition of acid. The lipomelanin sunscreen complex provides protection against harmful ultra-violet radiation. The level of UV protection may be varied according to the presence and properties of the ultra-violet absorbing compounds in the complex.
