Hi Lil'scrap. I have never heard of a skin prep that will improve scarring. The appearance of your scars will be determined by how your surgeon closes your incisions, how well you follow your postoperative instructions, and how your body heals. The final soft, thin, flat scar may take up to a year or longer of patience. It is easy to make scars worse, but hard to make them better. Sun avoidance is important, as is proper nutrition and a healthy lifestyle. While there are many products on the market which claim to reduce scarring, in my opinion, it is difficult to identify one that is clearly superior. Many patients ask about vitamin E and cocoa butter. These are inexpensive, and will not make anything worse. Whether or not they make a difference is hard to say. Few of my patients have had much luck with mederma or silicone sheeting. These products may be expensive. In my opinion, things that sound too good to be true usually are, so be careful about products that make extravagant claims about scar improvement. My advice is to ask your doctor.
