I had subcision surgery to two facial trauma scars bound down pretty tight. Now, I still feel a wad of tissue under my skin, still talk stiff, the wad is bigger and harder. The doctor put in some juvenderm after the procedure to help prevent the scar from getting bound down again. To make it worse, the area of scar is bigger and pocky whereas my skin is smooth. What would help get rid of those? TCA peel? Dermabrasion? What might have caused it?
