ve used mederma before on a larger scar, one that is about 3 inches in length and 1/2 cm in width, this one is about 2 years old and I remember using petroleum jelly a few times about 3 weeks after
surgery and then switched to mederma for about 3 months, this
scar is now flat, soft, white, and a bit 'wrinkly' I'm not upset by the apperance of this scar, although it is in an area that people usually don't notice, but I don't remember this one turning purple either.
