I had asked my doctor and he told me that I can wet the scars one week after the surgery and that I can also go swimming. Well, it's 3,5 weeks since I had the surgery and I have alreday gone swimming in the sea 5 times and have no problem. I went swimming for the first time 10 days after the surgery.But it's better for you to apply to the scars a healing cream, like madecassol, so that they will heal faster.
