My skin is a bit thin and my cheeks are sagging; is Ondari lifting very painful? lol

 I haven't gained weight, but as I get older, my skin elasticity has dropped drastically. My cheeks and jawline are sagging downwards, making my double chin look like it's overlapping. Every time I look in the mirror, my jowls and "bulldog cheeks" stand out, so I'm looking into lifting procedures to refine my facial lines. I'm an extreme wimp who absolutely cannot tolerate heat or pain, so many people recommend the microwave On-Da Lifting, which is said to be completely painless! Even someone with thin skin like me, will my cheeks be lifted perfectly into a V-line without worrying about hollowing? I'd also like to know the approximate total cost for a 3-session package at a dermatology clinic. If there are any先輩s out there who have consistently received On-Da Lifting to achieve a beautiful line without pain, please share all your vivid tips!
