Using a needle that is too long during a procedure can lead to injury to surrounding tissue. In electrolysis, the needle (or probe) is inserted into the hair follicle to deliver the electrical current needed to destroy the hair at the root. If the needle exceeds the appropriate length, it can penetrate too deeply, potentially impacting not only the targeted follicle but also adjacent skin and tissue structures. This can result in complications such as discomfort, swelling, or more serious injury, which might necessitate additional medical attention.

Proper needle length is crucial in ensuring both the safety and effectiveness of the treatment. In contrast, the other options may not pertain to the direct consequences of needle length as clearly. For example, while incorrect electrical power settings can lead to reduced effectiveness or safety issues, using the wrong needle length is more immediately associated with physical harm to the tissue surrounding the hair follicle.
