I don't have a flat forehead or a very hollow forehead, but
 the middle part of my forehead is a little bigger than a finger..?
 Should I say there is a dent? It's not noticeable when you just look at it, but when you look at it under the light, it's a little dent.
 I want to get filler in this area. How many cc should I put in...?
 I want to post a picture, but the dent is not visible in the picture.
 I'm not trying to make my forehead more convex, but I want to get it done in a way that slightly compensates for the dent.
 Among the people who got it for the same problem as me, how many ccs did they put in and see improvement?
