Should I change from titanium to Thermage..? You are a spineless person who keeps changing your words.. It’s me!.......

I've been looking for Ulthera Titanium Thermage all day long. Someone help me... Why is there so little information? I
 
was thinking about Ulthera, but I don't think it will work for my skin ㅠㅠ; (In the past, it wasn't for the face, but when I got the forearm in-mode, I was told that the skin was thin?)
 So... I was going to get titanium... but they also said that titanium lasts for a short time and needs to be applied periodically...
 Because of the nature of my job, it's difficult to go to the hospital often. ;;
Finally... I'm trying to get Thermage, but when I searched on Blind (I heard a lot of things like this come up on Blind),
 they recommended a place called ㅍㅇㅅ Dermatology, so I thought I'd try it there, but there aren't too many reviews here, so if you can recommend a hospital, please. ㅠ.ㅠ
 (initial consonant) I don't know if you write it down ㅠ.ㅠ Just leave it as private)
 And 300 shots is too little..? Should I do 600 shots?
