As far as I know, 80% is collagen, so it gradually disappears, and
 the remaining 20% ​​of artificial bone lasts a lifetime
 !
 
1. I heard that 60-80% of the injection amount lasts a lifetime, but
 20% is artificial bone. How is that possible?
 Does artificial bone have a greater contribution to volume than collagen?
 Or is this assuming that collagen is maintained to some extent?
 
2. I'm curious about the speed at which collagen falls out.
 Is it all lost in a few months?
 How much is lost in the beginning and the rest is lost gradually over a lifetime as people age?
 
3. I used Restylane on both sides for 1cc and
 I liked it on the first day (even if you add a little more) (I thought it would be tight)
 I guess it went right back on the second day, but it wasn't that good.
 One ampoule of Artecoll is 0.7cc. I heard that collagen disappears later. How many ampoules in total should I put in?
 (I want to get rid of wrinkles and add volume)
 
(I want to reduce the number of treatments as much as possible. I’m scared of blindness.)
