There are two methods to do chest piercing. The first method involves a simple barbell piercing which travels under the skin layer between the skin and muscle layer. The second method is a process called dermal anchoring where the jewelry or a dermal anchor is placed in a hole made into the skin layer down to the muscle layer. This jewelry has a metal foot whose function is to get anchored into the skin. Thus, both microdermal and dermal chest piercing are possible.
Alike all other body piercings, deep chest piercings are prone to a few risks, and thus needs good after care. It remains red, swollen, and tender in the first couple of weeks. You need to take care of it on a daily basis at least till the wound heals properly. If left unclean, it may get infected. Do not touch it unnecessarily, surely not with unwashed fingers. Always wash your hands with a good quality antiseptic soap before touching the piercing and the area surrounding it. Wash it once with a solution of common salt and water. To make this solution, take a cup of water and add a teaspoon of common salt, preferably non-iodized. Mix the ingredients well to make a solution.
