To minimize cicatrix formation and pitting, which needle practice should be avoided?

• A. Using a very small needle
• B. Using a short insertion angle
• C. Using a needle that is too large
• D. Using sterile technique

Answer: (C)

Controlling tissue trauma during electrolysis is crucial for reducing scar formation. Using a needle that is too large causes more mechanical damage to the follicle and surrounding dermal tissue and can widen the heat-affected area. This greater injury increases the likelihood of fibrosis and skin pits as the area heals, so avoiding an oversized needle helps minimize cicatrix and pitting.

In contrast, using a very small needle mainly changes how the current is delivered and can require more passes, but it doesn’t inherently cause the same level of surrounding tissue damage as a too-large needle. A short insertion angle affects the path depth of the needle but, when performed correctly, doesn’t automatically raise scar risk. Sterile technique is essential to prevent infection, which can worsen scarring if it occurs.
