The brand of glue we use where I work (outpatient surgery) is called Indermil. The directions from the company says that it is okay to shower after 48 hrs (our docs say 24 is okay). Do not apply creams, medications or ointments to the incsions. Do not rub or scrub the area, and pat dry after showering. Report to your doctor if you have redness, warmth, drainage or fever. The glue generally peels off on it's own in 7-10 days. Do not pull or pick at the wound or the adhesive.
