What is the procedure to get a Monroe Piercing hole less noticeable? (photos)

You have two options. The fastest would be to use a 2mm punch excision and remove the entire tunel and close it with a single 6-0 nylon suture. The scar from a  2mm punch usually heals beautifully. We use this approach in acne scar surgery frequently without any problems. Your other option is to resurface the scar with the ultrapulse co2 laser. It generally takes 2-3 treatments. This procedure will de-epithelize the tunel and during the healing process your tunel will apear less noticible. 

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

Frist you need to have realistic expectations! There will NEVER be a "perfect" result!!!! There will be a small scar.. So go from that point forward...
