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.
