The heated area surrounding the high-frequency needle typically takes what shape?

The heated area surrounding the high-frequency needle typically takes a teardrop shape due to the way electrical energy interacts with the tissue. When the high-frequency current is applied, it creates a concentrated area of heat at the tip of the needle, which then dissipates outward. The teardrop shape reflects the gradient of heat distribution, where the maximum heat is concentrated at the tip and gradually decreases as it extends into the surrounding tissue. This shape is essential for effectively targeting hair follicles and ensuring that the heat reaches the necessary depth to disrupt their growth, while minimizing damage to the surrounding skin. The tear drop configuration is a result of both the physical characteristics of the needle and the electromagnetic fields generated during electrolysis treatment, allowing for precise and effective hair removal.
