Can you really feel the effects of the lifting procedure?

I am posting this because I am curious if the effects of lifting procedures are truly noticeable in improving the jawline that has sagged with age. Lately, every time I look in the mirror, I see my cheeks sagging and my jowls protruding like a bulldog's, causing me immense stress. I feel that home care or firming creams simply won't be enough to fix it, so I am seriously looking into medical treatments. People around me strongly recommend equipment-based lifting procedures, saying they are the most effective way to refine the face line because they firmly pull up the skin from within, rather than injections. However, I am hesitant to make a decision because I am worried about potential side effects, such as facial hollowing due to fat loss or burns. If anyone has actually undergone lifting procedures for sagging skin, I would like to know if the before-and-after results are satisfactory enough to be clearly visible to the naked eye. Please share your firsthand know-how on how many sessions are typically required to maintain a V-line for a long time.
