%26quot;Whip mark%26quot; scars?
So me and my friend were messing around and we started whacking eachother%26#039;s legs with these plastic sticks. It hurt really bad but it was fun. But the problem is that it left %26quot;whip marks%26quot;. It has been about 4 days and they have yet to fade. Will they scar? I%26#039;ve been putting Mederma on them. Is there anything I should do to help them fade faster?
