Abstract
Abstract Gelled compositions containing a cosmetically and/or dermatologically acceptable hydrophilic medium, at least one gelling agent, and hollow particles, in which the medium contains at least 20% by weight of organic solvent, based on the total weight of the composition, and less than 50% by weight of water, based on the total weight of the composition, may contain an active agent which makes it possible in particular to prevent and/or control pigmentation of the skin or to control greasy skin and/or excessive weight.
