ABSTRACT:
A dermatological treatment and composition therefor are described for periodic and effective maintenance of a skin peel patient's subsequent skin condition. The treatment does not use radiation, can be performed quickly, is readily controlled by visual observation of the applied composition, and is self-limiting. The method includes forming a composition having a visualizing agent, a surfactant and an acid or acid equivalent dispersed in a carrier liquid, the concentration of the last not exceeding 30%; applying the composition to a predetermined area of the patient's skin in a quantity effective to result in a predetermined degree of mild exfoliation of the skin; determining degree of coverage of the area of skin by visual observation of extent of the visualizing agent; and maintaining the composition in contact with the area of skin for a period of time effective to result in the predetermined degree of exfoliation of the skin. Composition of this type are also disclosed. Preferable the acid or acid equivalent will be trichloroacetic acid and the surfactant will be a saponin or complex of saponins, preferably steroid saponins. The concentrations of the three principal ingredients, the amount of the composition used and the length of time of the application and treatment will vary according to the specific depth of peel or degree of maintenance which the dermatologist believes appropriate for a particular patient.
