Why is everyone choosing autologous fat grafting??

I think I have an ugly face (if I had to choose between pretty and not).
But I have never thought about having plastic surgery or surgery.
I was careful to live as I looked, and it made me look scary lol.
 
But since last year,
 I started thinking that my face looked ugly and old.
 
Then, I found out about the procedure and tried selling my handmade products for a few days.
My biggest concerns right now are 'forehead' and 'nasolabial folds', but
 in the flood of information, I only looked for 'forehead'
 
----------------------- -------------------
 Forehead filler Elance (collagen regeneration filler)
 - Advantages: Lasting power
 - Caution: Only need to put in a little, 2cc on the forehead? , It is dangerous to put this on anything other than the forehead
 - Disadvantage: It is expensive and costs a lot of money to remove (it cannot be easily dissolved like HA filler) -
 Favorite hospital: ㄷㅆㅇ (the director calls himself an Elance expert. But he is not a plastic surgeon, other plastic surgery) No reviews)
  
Forehead autologous fat grafting
 - Advantages: Engraftment without immune rejection
 - Caution: Must be raw fat
 - Disadvantages: Only at the beginning, 20-30% of swelling remains on the second day: Almost all gone?, thighs where the fat was removed are bruised and very painful
 - Favorite hospital: ... I don't know, there are too many hospitals......
 ------------------------------- -----------
 
The one I saw and liked the most was Elance.
But why aren’t there many reviews????

Why are there no people who have done Elance?
 Why is everyone choosing autologous fat grafting instead of Elance??

I'm really curious.
 Please tell the eunuch who has the procedure.
 

And the angel who will save
 the eunuch, please tell me how to get rid of nasolabial folds!!!!!!
