Abstract: Methods, systems, and devices for integrated photo-responsive contouring treatment are described. Methods include identifying a region of skin corresponding to a contouring treatment of the skin. The region of skin may be provided with a photo-responsive material overlying a portion of the region of the skin. Methods may include identifying one or more treatment regions overlapping the photo-responsive material. The treatment regions may be identified at least in part to apply the contouring treatment. Methods may include determining an irradiation profile for each of the one or more treatment regions to contour each respective treatment region as part of applying the contouring treatment. Methods may also include irradiating the photo-responsive material at the one or more treatment regions in accordance with the respective irradiation profiles. Irradiating the photo-responsive material may induce a localized change in shape of the photo-responsive material in the respective treatment regions.

Abstract: Provided is a composition, in the form of an emulsion comprising a polyester from the esterification, with a polycarboxylic acid, of an aliphatic hydroxycarboxylic acid ester comprising at least two hydroxyl groups and at least one nonionic cellulose derivative comprising one or more hydrophobic substituents containing from 8 to 30 carbon atoms. Also provided is a composition comprising an active agent chosen from C-glucoside derivatives, a pasty fatty substance and a nonionic cellulose derivative comprising one or more hydrophobic substituents containing from 8 to 30 carbon atoms. Emulsions are made possible containing pasty fatty substances that are stable, even without an emulsifying surfactant or with a low content thereof (for example less than 3%), and which afford good sensory pleasure, even when the composition comprises a high content of pasty fatty substances. The emulsions can also contain active agents chosen from C-glucoside derivatives and cucurbic acid derivatives that are stable.
