How do you hide an unhealed eyebrow piercing?

Wear shirts that cover your stomach

when at the beach around people who you don't want to know, wear a cover-up or lose t-shirt

Get a clear ring/bell bar (6 months or more after the piercing) so that it's less noticable

Cover it with a band-aid and make up some story about falling and scraping your stomach on the asphalt IF people ask

Don't play with it or draw attention to it

get a clear navel retainer, online, you can put it in almost dirtectly after the peircing.
