Your Microdermal/ Skin diver piercing will have a surgical dressing covering it. This initial dressing must remain on for the first 48 hours (if it should accidently come off simply re-cover with a new dressing). When the 48 hours is up you must remove the dressing (soaking the area in warm water first is advisable).
Hereof, can I shower with my dermal piercing?
It’s okay to let sudsy water run over your dermal piercings in the shower, but you shouldn’t soap them up directly with anything but a mild, fragrance-free soap, and then only occasionally if you feel it’s absolutely necessary to do so.
