Which combination of adjustments helps minimize pitted scarring during thermolysis?

• A. Using a larger diameter probe, decrease the timing and intensity and avoid shallow insertion
• B. Using a smaller diameter probe and increasing timing
• C. Raising the temperature and keeping insertion shallow
• D. Avoiding any heating and performing at extremely slow pace

Answer: (A)

The main idea is to limit thermal damage to surrounding tissue while effectively targeting the follicle. A larger diameter probe spreads the energy over a wider area, reducing the risk of creating a highly concentrated burst of heat in a small spot, which helps protect the surrounding dermis. Pairing that with decreased timing (shorter pulse duration) and lower intensity keeps the heat generation modest, further minimizing surface and shallow tissue injury. Avoiding shallow insertion is important because placing the needle too close to the surface concentrates heat in the epidermis and superficial dermis, increasing the chance of pitted scarring. Together, these adjustments deliver enough energy to the follicle without overly heating adjacent tissue, reducing the likelihood of pitted scarring.
