What is the term for current concentration at the probe tip in thermolysis?

• A. Probes
• B. Displacement
• C. Point Effect
• D. Electrode

Answer: (C)

The term is the point effect. In thermolysis, the electrical energy is focused at the very tip of the probe, where only a tiny amount of tissue is exposed. This small exposed area means the current density is extremely high at the tip, so heat is generated rapidly there. The intense, localized heat coagulates and destroys the hair follicle while minimizing damage to surrounding tissue. This is what makes thermolysis distinct: the heating is concentrated at the needle’s point, not spread evenly along the shaft. The other terms don’t describe this phenomenon—the probe is the instrument, displacement isn’t about energy concentration, and an electrode is the conducting part but doesn’t capture the idea of heat being generated primarily at the tip.
