What critical factor should be considered during electrolysis treatment procedures?

During electrolysis treatment procedures, the depth of needle insertion is a critical factor because it directly affects the effectiveness of the hair removal process. Proper needle insertion depth ensures that the current is delivered to the hair follicle, targeting the papilla where hair growth is stimulated. If the needle is inserted too shallow, the current may not reach the follicle effectively, thereby diminishing the efficacy of the treatment. Conversely, if the needle is inserted too deeply, it may cause unnecessary discomfort and potential injury to surrounding tissues, which can lead to complications such as scarring or infection.

The practitioner must be skilled in assessing the appropriate depth for different hair types and skin conditions to maximize treatment results while minimizing discomfort and side effects. This precision is essential for achieving safe and effective electrolysis results.
