Personally, I find the best results are treatments performed once every 1-2 years.
The doctor's manual skills are important, but they forgot and did it at another hospital because it was cheap, and my cheeks were lumpy and my face was ruined for a yearㅜㅜ I got
almost 700 pounds broken by having this and that done at the same time...
I'm satisfied with the results, and I plan to only do thread lifting at this hospital.
