Non-ablative approaches with infrared and radiofrequency energy sources have been shown to reduce skin laxity, but studies have focused on individuals with early-stage, mild-to-moderate degenerative dermal changes.
The purpose of this prospective study was to evaluate the safety and efficacy of an infrared light device for the treatment of skin laxity in patients with soft tissue ptosis of the lower face and neck characteristic of the sixth decade of life and beyond.
Thirteen females, aged 58-83 years old (average: 64 years), were treated with a filtered 1100-1800 nm infrared light-based device. All individuals presented with ptotic soft tissue, but varied in the extent of skin laxity from no visible laxity to having pendulous excess skin. Two treatment sessions were provided at monthly intervals. The individuals returned for follow-up visits at 1, 3 and 6 months after the second treatment. Twelve of the individuals completed the study.
Changes were dramatic for those individuals in whom the skin envelope appeared to drape separately from deeper soft tissue. No treatment complications were noted.
Infrared light source-induced skin tightening may be induced even in older individuals.
已证明使用红外线和射频能量源的非剥脱方法可减少皮肤松弛，但研究主要集中在患有早期轻度至中度退行性皮肤变化的个体。
这项前瞻性研究的目的是评估一种红外线设备对患有面部和颈部软组织下垂（具有60岁及以上年龄段特征）的患者治疗皮肤松弛的安全性和有效性。
13名年龄在58 - 83岁（平均64岁）的女性接受了基于1100 - 1800纳米过滤红外线的设备治疗。所有个体均存在软组织下垂，但皮肤松弛程度各不相同，从无明显松弛到有多余的下垂皮肤。每月进行两次治疗。个体在第二次治疗后的1、3和6个月返回进行随访。12名个体完成了研究。
对于那些皮肤包膜似乎与深层软组织分开下垂的个体，变化显著。未观察到治疗并发症。
即使在老年个体中，红外线光源也可能导致皮肤紧致。
