New extracts of microalgae, halophytes and psammophilous plants are suggested, obtainable by treating said microalgae and plants with a solvent selected from the group consisting of C1-C4 aliphatic alcohols, ethyl acetate, water or their mixtures, removing the dissolved extracts from the residues and recovering the pure extracts from the solvent. The extracts show excellent activity as regulators of the metabolism of human sebaceous glands. |
