What is the term for black and blue marks seen under the skin after inserting a probe into a follicle?

The term for black and blue marks seen under the skin after inserting a probe into a follicle is ecchymosis. This term specifically refers to the discoloration of the skin resulting from bleeding underneath, often due to trauma or injury, which can occur during procedures like electrolysis. When a probe is inserted into a follicle, small blood vessels may be damaged, leading to localized bleeding. The blood seeps into the surrounding tissue, causing the characteristic bluish or purplish marks known as ecchymosis.

Understanding this term is essential for electrologists since it helps in recognizing normal post-treatment reactions versus those that might indicate complications. This awareness can enhance client care and reinforce the importance of proper technique to minimize such occurrences.
