Are lifting procedures really effective for refining facial lines?

Lately, I’ve been incredibly stressed about my double chin and jowls every time I look in the mirror. I’m the type of person whose facial lines collapse immediately upon even a slight weight gain, so my jawline stays the same even after dieting. Everyone around me has recommended lifting treatments, so I’m considering biting the bullet and getting one this weekend. Since I work, I plan to visit after work using an evening appointment. How long should I typically allocate for the entire visit, from the consultation to the actual laser lifting procedure? Also, I am extremely sensitive to pain; I’m wondering if the pain is tolerable even without general anesthesia. I’m also worried because some people have mentioned the possibility of side effects like sunken cheeks. For those who have received this treatment, please share your honest feedback on whether you truly felt the value of this lifting procedure in refining your facial lines!
