Abstract
Solubilizing compositions are provided. The compositions comprise at least one zwitterionic surfactant and at least one nonionic surfactant. In one embodiment, the compositions may be useful for solubilizing and remodeling and/or removing tissue on or beneath a patient's skin, optionally in conjunction with the application of energy to a region of interest on the skin. In one embodiment, at least one analyte may be collected and analyzed from the solubilized tissue.
