I recommend silicone gel for most people and silicone sheeting for those who have a strong tendency to make a thick scar. Time is the most important factor in scar quality.
One of the best treatment is time, scars take up to one year to mature, the other is sunscreen so you don't burn them and darken them permanently. As far as topical scar treatment, silicone strips are recommended for breast reduction scars. Your PS probably sells them in the office, they are re-usable and easy to apply.
