Thermolysis needle reaction

James Schuster is a Wisconsin dermatologist who has prepared several videos and slide presentations on hair removal. Dr. Schuster performed several controlled tests of electric tweezers to demonstrate that the devices cannot perform as claimed.

Above are examples of electrolysis probles using alternating (high-frequency) current. The probes are placed at various depths in egg white, which has similar properties to collagen in human skin. Note the difference in heating patterns depending on depth of insertion.
