Well, there are a lot of factors that can cause creases. The biggest concerns timing after your surgery. Creases appearing shortly after surgery very often disappear as swelling subsides. Compressive garments worn after surgery are certainly helpful in reducing swelling more quickly but because the fabric can be thick and rather coarse then creases could form on the skin. As swelling subsides generally such creases disappear.
Hello dear, thanks for your question and provided information as well. I suggest you to be patient, folds are common after surgery, because of the swelling that can stay about 2 months
