The neck ages faster than the face it carries: its skin is thinner, has fewer sebaceous glands, gets less sunscreen, and moves thousands of times a day. Horizontal lines, crepey texture and laxity are three different processes that usually arrive together.

It then takes more: daily flexion cycles, decades of sunlight that facial sunscreen never covered, and the constant downward pull of the platysma. Necklace lines are fold lines — creased into thin skin by movement and posture. Crepiness is collagen and elastin depletion showing as micro-wrinkling. Laxity is the same ligament-and-support story as the lower face, one storey down — often continuous with jowling.
Thin tissue rewards precision, not aggression. Bulk dermal heating with monopolar radiofrequency has published evidence for skin tightening on the face and neck [1], and microfocused ultrasound reviews cover the décolletage and neck at conservative depths [2]. Dr Sin Yong treats the neck as part of the lower-face unit — the Time Freeze Laser Lift and neck & hand revitalisation protocols pair energy for laxity with skin-quality work for crepiness, because tightening crepey skin without treating its texture leaves shiny, thin-looking results.
Neck creams hydrate — worthwhile, but hydration is not collagen. “Neck firming” exercises strengthen platysma, the very muscle whose pull contributes to banding. And treating the face while ignoring the neck produces the tell every observer reads: a rejuvenated face on a recorded-history neck.
“The face can look ten years younger than the neck — and the neck always tells.”

Early necklace lines are usually postural — flexion folding thin skin — plus genetics. They are fold lines, not age lines, which is also why they respond differently.
Reducing sustained flexion helps, as does extending sunscreen and skincare below the jaw. Lines already creased into the dermis need active treatment to remodel.
No — it is thinner, heals more slowly and scars more easily. Settings, depths and expectations are all adjusted; this is not a region for aggressive parameters.
Platysmal bands — edges of the sheet muscle becoming prominent. They are a muscle issue, treated differently from skin laxity, and assessment distinguishes the two.
Submental fullness is a separate issue — see the double chin page — but it often coexists, and treating one without assessing the other disappoints.
It can be brought dramatically closer. Honest framing: the neck responds more slowly and needs maintenance sooner, because it starts with less reserve.
