Brief summary: Up to 6 subjects will be enrolled. Subjects who have already chosen to have a surgical facelift procedure will be enrolled. Subjects will receive selective Ulthera® ultrasound exposures in the pre-auricular regions. Subject will return for a follow-up visit up to 48 hours post-treatment, on the day of their rhytidectomy. Study images will be obtained pretreatment, immediately post-treatment, and at the follow-up visit.

Detailed description: This study is a prospective, single-center clinical trial. Subjects will be enrolled at the investigator's discretion if they meet inclusion/ exclusion criteria and provide written informed consent. Enrolled subjects will be treated with an assigned transducer based on their order of enrollment. At the study follow-up visit, subjects will undergo resection of the treated tissue for histological analysis prior to their planned rhytidectomy procedure.

* Male or female, age 30 to 65 years scheduled for rhytidectomy.
* Subject in good health.
* Understands and accepts the obligation not to undergo any other procedures in the areas to be treated.

* Severe or cystic acne on the area to be treated.
* Presence of a metal stent or implant in the facial area to be treated.
* Inability to understand the protocol or to give informed consent.
