Abstract

The invention relates to the use of melanin in the form of natural malanin granules as a sunscreen agent. In a preferred embodiment the pigment Eu-melanin is used and preferably the granules are greater than 1 mu in diameter. The agent is preferably employed with a suitable carrier as an ointment, cream or gel. The invention also provides for the use of keratin and the hydrolysis products therefrom to be used as a sunscreen agent.
