First Claim
Patent Images
1. A method for eliminating dermal content through the skin, the method comprising:
- exposing a region of the skin to electromagnetic radiation to create a treatment zone wherein the treatment zone has substantially intact stratum corneum and vacuole below the stratum corneum; and
encompassing the dermal content in the vacuoles wherein the dermal content is exfoliated through the skin.

Abstract
Subjects treated with nonablative fractional photothermolysis (FP) have an intact stratum corneum, but can have microscopic lesions and vacuole formation within the epidermis. The vacuoles thus formed can trap dermal material and extrude it through the epidermis. Thus, FP can be used for the treatment of recalcitrant melasma, solar elastosis, and tattoos.
