Where does the point effect occur during a shallow needle insertion?

The point effect occurs at the tip of the needle and the upper part of the follicle near the skin's surface during a shallow needle insertion. This phenomenon is important in electrolysis, as it refers to the precise location where the electrical current is delivered to effectively disrupt hair growth.

When the needle is inserted shallowly, it ensures that the current primarily targets the area just below the surface of the skin, where the hair follicle begins to develop. This is crucial for effectively treating the hair bulb and surrounding cells responsible for hair growth without causing unnecessary trauma to deeper structures or the epidermis.

Understanding this point effect is critical for practitioners, as it enhances the effectiveness of the electrolysis treatment while minimizing pain and side effects. It also emphasizes the need for proper technique in needle placement to optimize results in hair removal procedures.
