Removing a piercing - do you have any recommendations on anything to encourage healing and prevent scarring?

I have had good success by using TCA CROSS, a very quick, simple and relatively inexpensive technique, to close unwanted piercing holes. It typically takes several treatment sessions (3-4) to achieve optimal results. Best of luck.

If you've had your nose pierced for a while, when you take the ring out the hole is unlikely to ever close. You can have it surgically closed which should change the hole for a small round scar, but, that will always be present.
