Due to my genioplasty I have a deep labiomental groove and my chin looks kind of chopped off from the front and I was trying to achieve a more v-shaped chin line from the front. I got fat added to both areas and it looked fantastic. Unfortunately it didn't last. I was wondering if I could inject some filler to both these areas without giving the soft, swollen look some fillers can give you. Which filler would be most recommended in that case?
