Neck laxity occurs when collagen and elastin fibers weaken, leading to sagging skin and reduced firmness. Sun exposure, repetitive neck movements, genetics, and significant weight changes can accelerate the process.

First-line care may include collagen-stimulating injectables such as Sculptra or Ariessence Pure PDGF+ to restore firmness and elasticity, RF microneedling to tighten and remodel skin, and/or IPL or Sciton Moxi to improve texture and tone.

Adults with mild to moderate neck laxity seeking a nonsurgical approach to firmer, smoother skin.
