Can i swim a year after my skin graft?

At one year you should be able to go swimming without any damage being done to the area as long as its healed correctly. If you are still concerned, you should call your doctor and discuss it with him.  You then can decide if you want to see them again or if you have further questions. Enjoy the swim.

At one year out it is perfectly fine to swim. Your site is well healed and there would be no problem with swimming."This answer has been solicited without seeing this patient and cannot
