example 1

[0099] Table 2 shows the formulations of three rinse-off personal care compositions showing the amounts of components added as obtained from suppliers. Therefore, if the components are obtained in the form of a solution, the amount of the solution added is included hereinafter. Composition A and Composition B are comparative examples of Composition C comprising 0.5% zinc pyrithione. For each of the tests described below, subjects were tested with a dry skin rating of about 2.5 to about 4.0.

[0102] figure 1 Shown is a graph of skin moisture meter measurements taken over a 21-day period, with each measurement taken 3 hours after application to the skin. Measurements taken on Day 14 and Day 21 respectively showed that Composition C containing zinc pyrithione provided higher skin moisture meter readings than the control compositions Composition A and Composition B, thereby Provides greater improvement in skin hydration.

Abstract

A method of enhancing skin hydration, the method including applying a rinse-off personal care composition comprising at least one of a zinc-containing material and a pyrithione material to non-diseased skin of an individual.

Description

technical field [0001] The present disclosure generally relates to methods of enhancing skin hydration and methods of improving disease-free skin through the administration of zinc and / or pyrithione-containing materials. Background technique [0002] Although clear skin is generally free of major conditions such as disease, infection, or fungal infection, a person with clear skin may still experience dryness. Accordingly, it would be desirable to provide methods of improving disease-free skin by applying zinc and / or pyrithione-containing materials to the skin of an individual. Contents of the invention [0003] A method of enhancing skin hydration comprising applying to the disease-free skin of an individual a rinse-off personal care composition comprising at least one of a zinc-containing material and a pyrithione material. [0004] A method of enhancing skin hydration, the method comprising: applying to the disease-free skin of an individual a rinse-off personal care co...
