摘要

Cosmetic non-therapeutic use of at least one fluorocarbon (I) in a topical composition for reducing the pore size of the skin, preferably facial skin, is claimed, where (I): is a perfluorinated hydrocarbon compound, in which at least 90%, preferably 100% of the hydrogen atoms are replaced by fluorine atoms; exhibits no other heteroatoms in the molecule except carbon, fluorine and optional hydrogen; is present as a liquid under normal conditions; and exhibits a molecular weight of 250-700 g/mole.
