Hi guys. I have a big scar in my cheek and found out the world of prosthetics which amazed me. I saw some prosthetic work that looks like real skin in "A quiet kind of love" and "Looper", I was just wondering about the edges. Some edges from these movies looked flawless and others were a bit noticeable. How hard is to create perfect invisible edges? Do edges remain the same throughout the day? If not, how hard is the maintenance? Thanks for your attention, this makeup could be a life saver.
