I emailed my pictures to a board certified surgeon and she replied saying that my skin and tissue may be too firm to receive more than 1000cc. She said because im young (19) my skin should be very firm. I really want very big buttocks and wider hips. Are there any things I could do to make it less firm? My friend has told me that I could buy a dermaroller to increase collagen production and make my tissue more elastic. Will it work?
