How can blanching occur during treatment?

Blanching during treatment is primarily a result of shallow insertion or using high energy intensity. When the electrode is inserted only superficially into the skin, it can lead to the destruction of the small blood vessels located just below the dermis. This destruction causes the blood to move away from the area, which leads to a temporary whitening or blanching effect on the skin's surface.

Using high energy intensity can have a similar effect. When a high amount of energy is applied to the area during electrolysis, it can cause rapid heating and subsequent vaporization of tissue and blood in close proximity, leading to blanching. This is particularly relevant in electrolysis, where precision in energy delivery is essential for effective treatment without causing excessive damage to surrounding tissues.

In contrast, deep insertion or using a larger needle may not produce blanching as they engage different mechanisms. Deep insertion might affect deeper tissues and blood vessels, while a larger gauge needle could decrease the chance of blanching by allowing for greater blood flow and less localized tissue destruction. Inadequate sanitation procedures would generally not result in blanching but could lead to infection or other complications, unrelated to the blanching phenomenon itself.
