摘要
Cosmetic/dermatological compositions useful for the treatment of a variety of dermatological conditions, including keratinization disorders, acne, eczema, psoriasis, etc., comprise an invert emulsion containing at least one active agent sensitive to the presence of water, notably a derivative of vitamin D, and solubilized in a glycolic or hydroglycolic dispersed hydrophilic phase, a lipophilic continuous phase and an emulsifier having an HLB ranging from 2 to 7; these invert emulsions exhibit good stability and avoid crystallization of the active agent and/or chemical degradation thereof.
