Which factor contributes to blanching according to the material?

• A. Deep insertions only
• B. Increased humidity
• C. Over treatment and shallow insertions
• D. Long treatment duration with no insertions

Answer: (C)

Blanching happens when the tissue is stressed by how the current is delivered, so the safest, most consistent cause is when energy is applied too aggressively near the surface and the needle is placed too shallow. When insertions are shallow, most of the current sits near the epidermis, causing the superficial capillaries to constrict and the skin to pale. If you also use too much current or leave it on too long, you intensify that surface effect, increasing heat and tissue trauma and making the blanching more pronounced. Deeper insertions place the current within the follicle where it’s intended, reducing the surface impact and thus blanching. Increased humidity doesn’t directly cause blanching in this context, and a long treatment with no insertions delivers little to no current, so blanching wouldn’t occur.
