Microstructures and method for treating and conditioning skin which cause less irritation during exfoliation
First Claim
1. A microstructure apparatus, comprising:
- a substrate and a plurality of microelements affixed upon a first surface of said substrate;
said plurality of microelements being of predetermined sizes and shapes for use in scraping skin cells from skin when said microstructure apparatus is placed upon said skin and moved in at least one direction, said predetermined sizes and shapes including at least one substantially sharp edge at a distal end of the microelements, and said predetermined sizes and shapes having a characteristic such that the microelements do not create substantial focal discrete points of pressure on said skin.

Abstract
An improved method and apparatus is provided as a system to enhance skin appearance and health, in which skin is cleaned (or exfoliated) and conditioned by use of microelements affixed to a base element or hand-held patch. The dimensions of the microelements are controlled so as to remove a certain number of layers of skin cells and to accumulate those skin cells, along with other foreign substances, into areas between the microelements. In addition, a conditioning compound or therapeutic active can be applied to the exfoliated skin to enhance the skin. Moreover, the amount of accumulated skin cells represents a self-limiting maximum quantity that cannot be substantially exceeded regardless of the number of attempts by a user to re-use the microstructure apparatus. Some of the microelement shapes are purposefully designed with distal ends that exhibit sharp edges rather than sharp tips to reduce skin irritation.
