In a shallow insertion, where does the HF point effect occur?

The HF point effect, or high-frequency point effect, occurs in the upper part of the follicle and the tip of the needle during electrolysis. This phenomenon is significant because it highlights how electrical currents can effectively target the hair follicle when the electrode is positioned shallowly.

When the needle penetrates only lightly into the skin, the energy, or heat produced by the high-frequency current, is concentrated in the upper follicle areas. This localized heating can assist in the destruction of the hair matrix cells which are crucial for hair regrowth. The effectiveness of electrolysis is therefore maximized in this configuration, as it ensures that the active region of the hair follicle receives enough energy without causing unnecessary trauma to the deeper structures of the skin.

In contrast, a deeper insertion might not take full advantage of the HF point effect and could result in less efficient treatment. The surface of the skin typically does not benefit from this targeted heating, as the main goal of electrolysis is to disrupt hair growth at the follicular level.
