A lifestyle lift is a trademarked term. It is not an actual surgical procedure. The procedure that the term generally refers to is a lower facelift and neck lift. There is nothing revolutionary about a lifestyle lift. In fact, the lower third facelift using the smas plication or imbrication (muscle anchoring terms) techniques are some of the most traditional facial rejuvination procedures in existence.
I personally do many of my facelifts under local anesthetic in the office using tumescent anesthetic and oral Ativan. In order to achieve effective, lasting results I always educate my patients thoroughly on the healing process. I tell them that they typically need about 10-14 days off of work. Much of the visible swelling and bruising will resolve within the first couple of weeks but the patient may feel swelling for several months. Soreness is very patient dependent. I have had patients tell me that they were virtually pain free after 5 days and I have had patients tell me that it took 2-3 weeks for the soreness to fade. It's very difficult to predict how each patient will respond in the healing process. Remember that this is your face. A technically sound lift requires a commitment to the healing process and an understanding that the final results may not manifest for a few months. Good luck!
