Treatment of Neck Laxity with Radiofrequency and Infrared Light
Neck rejuvenation predominantly targets skin laxity, with a lesser emphasis on rhytides and photoaging. Neck laxity may increase with age due to progressive prominence of platysmal bands, loss of bony mass along the mandible and mental region, increased subcutaneous fat, and loosening of the connective tissue framework. Additionally, photoaging may result in progressive solar elastosis, which may contribute to rhytides, laxity, and poor texture. Important limitations to treatment include the anterior location of the thyroid and parathyroid glands, which must be shielded from deeply penetrating wavelengths. The increased scarring risk on chest secondary to pulsed light indicates a potential increased scarring risk on the inferior aspect of the neck as compared to face, thus necessitating greater care and lower fluences in this region. Overall, neck rejuvenation targets skin laxity bringing skin tightening technologies to the forefront in this category.
