Quick question.. am I supposed to be using skin prep everytime I change my appliance? (only 2 1/2 months out, still kinda new to this) I haven't been and I am lucky to get 3 or 4 days. My skin looks fine. So, even if my skin looks fine, will the skin prep help to extend my wear time? Also, I have kind of a short stoma.. have recently switched to convatec, convex wafers which are working better than the regular wafers, but still not where I want the wear time to be. Is there anything else out there that can help my "shorty" get better wear time?
