How Soon Can I Use Paper Tape on an Abdominal Incision?

It would be best if you spoke with your surgeon regarding how he or she will handle your incision.  In my own practice I tend to avoid tapes and adhesives  because in some patients they can lead to blistering and changes in the pigment of the skin.
In my own practice I generally dissuade people from using lotions and potions until a week or two after surgery until the superficial part of the wound has healed completely.  Checked in with your surgeon about how here she handles these incisions.
 
Good luck

As long as your surgeon does not object, I think you can start as soon as 48 hours post-operatively.

Thank you for your question. Rather than using paper tape over your incision to minimize the appearance of a scar, we suggest using a silicone sheeting cream. We recommend BioCorneum. We use this regularly in our practice. We have found using it minimizes and softens the appearance of scars. If you have no dressings over your incisions, you can start using the cream as soon as your surgeon gives you the okay.
