Needle Hole in skin (under electron microscope) applies to SMP

This shows a needle puncture in the skin that is clearly present, after the needle exits the skin.  For those people who get Scalp Micropigmentation, this is also present, just in the thousands. The hole usually fills in quickly from below, but when doing SMP, I always ask the patient not to shampoo or use alcohol in any manner for 3 days after getting SMP.  If this rule is not followed, then the detergent will go through some of the holes and cause the tattoo ink to dissipate, making what was a “DOT” into a “Blob”
