Instruction on how to use SCARBAN C-Section. Scarban C-Section is a self- adhesive, washable, medical, silicone sheet, for the treatment and prevention of abnormal scars after a Caesarean section. You can start using Scarban immediately when the wound has closed, if there is no scab formation and if any stitches have been removed. Existing scars can be treated immediately with Scarban. Apply Scarban for at least 12 and up to 23 hours a day. The longer your daily treatment with Scarban, the faster you can expect results.
