Skin laxity is the result of both intrinsic and extrinsic factors. Genetics, natural aging, ultraviolet exposure, lifestyle, weight fluctuations and smoking may all contribute. Laxity may affect the eyelids, face, jawline, neck, abdomen, hands and elsewhere. The optimal treatment depends on the severity and an individual’s underlying skin tone. A number of lasers and energy sources offer nonsurgical alternatives to laxity and can very effectively tighten the skin and rejuvenate. In general, these devices work by heating the skin’s deeper layers, which can stimulate new collagen deposition. Many of these procedures have very little downtime. Results are seen gradually over the first several months after treatment. Oftentimes, these energy-based devices can be combined with botulinum toxin or filler injections to achieve optimal results.
