The human skin heals with scars and therefore scar formation is inevitable even after aesthetic surgery. The quality of the scar depends mainly on surgical technique (how much force is applied on the scar during the healing period), the sutures used (absorbable vs non-absorbable) as well as the patients genetics. Sun exposure and nutrition also have a major effect on the quality of the final scar. It takes 1 year for the scar to mature and gain its final appearance. This usually results in fading of the scar color which makes it less visible. Sun exposure can result in a permanent hyper-pigmentation of the scar during the healing period. Genetically some skins are more prone to hypertrophic scars or keloids. Therefore proper scar management during the healing process period (first 6 months) is mandatory for a good result. This includes use of silicone tapes and proper sunscreen protection. Silicone gels or tapes are usually administered to prevent the surgical scars to become hypertrophic and hence achieve the best scar quality . When to use is totally the preference of the surgeon. In my practice for breast and body aesthetics, I usually use a special water resistant strip on the incision lines during surgery which are left in place for a month allowing the patient to take shower immediately the day after surgery. This is of major comfort to the patient as he/she does not need to change any dressings and can freely return back to routine life. After removal of the tapes 1 month post surgery, I usually administer silicone gels and tapes for controlling the scar quality.
