APPARATUS AND METHODS FOR MODIFYING KERATINOUS SURFACES
First Claim
1. A method of analyzing and treating tonal imperfections on human skin that comprises the steps of:
- a. providing one or more nozzles;
b. taking an image of skin adjacent the one or more nozzles;
c. calculating a plurality of local L values of the skin near each nozzle;
d. calculating a background L which is the arithmetic average, median, or mean of a plurality of local Ls;
e. identifying a skin deviation where the absolute value of the difference between a local L and the background L, Δ
LM, is greater than a predetermined Δ
LS value; and
,f. treating the skin deviation with a treatment composition.

Abstract
A method and device for analyzing and treating tonal imperfections on human skin. The method has the steps of providing one or more nozzles and taking an image of skin adjacent the nozzles. A central processing unit calculates a plurality of local L values of the skin near nozzles and calculates a background L. The background L may be the arithmetic average, median, or mean of the plurality of local Ls near nozzles. Skin deviations are areas of skin where the absolute value of the difference between a local L and the background L, ΔLM, is greater than a predetermined ΔLS. Skin deviations are identified by this method and then treated with a treatment composition.
