Skin Care Tip: Scar treatment

I had a scar about an inch long on my cheek from a car accident. I had it revisioned by a plastic surgeon, but still the scar was visible and annoying. I massaged the scar with Vitamin E oil for about 3 min every night, and applied scar reducing gel called Mederma. Also, I made sure I wear sunblock during the day. After 3 months from the accident, I started get microdermabrasion every two weeks for 4 months. It has been exactly 8 months from my accident, and the scar is invisible.
