Well, there is not too much you can do for scars. Silicone sheeting most accepted treatment
The best products to treat your scar provide hydration, warmth and a silicone occlusion. Also stimulating oxygen supply (blood flow) by massage and mild exercising has shown to be effective. In fact there is no single optimal product that can prevent or eliminate scars. The most accepted treatment is silicone gel sheeting.
Other products
Studies have shown silicone gels or ointments are less effective than silicone sheeting. In a preliminary clinical trial, Imiquimod 5% (Aldara) cream has shown to improve the appearance of new hypertrophic scars after surgery but more research has to be done. Other treatments like topical vitamin A and E, pressure therapy and polyurethane dressings could be used.
