'Tech neck' lines
Horizontal neck lines · skin boosters, neuromodulator and lasers for the neck
'Tech neck' has moved from a physiotherapy term to a beauty one, with surveys of women's ageing concerns and a wave of neck creams and neck-focused clinic menus in 2024–25 blaming hours spent looking down at phones.
Search interest: about 300 searches a month in Singapore for “tech neck” (Ahrefs, October 2026).
Horizontal lines, vertical bands and loose skin are three different necks; the mistake is treating all three with whatever was bought that month.

What works for 'Tech neck' lines?
Established. Horizontal lines, vertical bands and loose skin are three different necks; the mistake is treating all three with whatever was bought that month. A 2026 systematic review and meta-analysis of eleven studies found hyaluronic acid filler improved horizontal neck lines on aesthetic and wrinkle scales with mild, transient complications, but half of patients were retreated within twelve months and most studies were small and uncontrolled.
- Verdict
- Established Long clinical track record. Results depend on selection and technique more than on the device.
- Evidence base
- 3 PubMed-indexed studies cited below, including systematic reviews, randomised trials.
- Suits
- Defined horizontal lines in a neck with otherwise reasonable skin; younger patients whose lines are creases rather than laxity.
- Not for
- Loose, crepey neck skin or heavy bands, which need tightening or muscle treatment first; anyone expecting a cream or posture change to remove established lines.
- In Singapore
- Hyaluronic acid skin boosters and fillers are HSA-registered devices injected by doctors in Singapore; botulinum toxin is a prescription-only medicine and is not advertised to the public.

What it is
Horizontal creases across the front of the neck, present in some people from their twenties and deepened by repeated flexion, sun and thinning skin. They are a different problem from vertical platysmal bands and from loose neck skin, and each of the three has its own treatment.
How it works
A horizontal neck line is a fold in thin, sun-damaged dermis over a muscle that creases it thousands of times a day. Hyaluronic acid skin boosters or thin fillers placed along the line fill and hydrate the crease; a small dose of neuromodulator reduces the platysma's creasing; fractional lasers and RF microneedling rebuild dermal thickness so the fold holds less. Posture helps less than the name implies, because the lines form early and the skin, not the angle of the head, is the variable.
What the evidence says
A 2026 systematic review and meta-analysis of eleven studies found hyaluronic acid filler improved horizontal neck lines on aesthetic and wrinkle scales with mild, transient complications, but half of patients were retreated within twelve months and most studies were small and uncontrolled. A prospective series and a randomised comparison of subcision plus filler against filler alone support combination approaches. Evidence for lasers and neuromodulators on horizontal lines specifically is thinner and mostly extrapolated from facial work.

What the studies show
- systematic review
Eleven studies in 379 patients showed improvement in aesthetic and wrinkle scores with a 14 per cent rate of mild, transient complications and a 50 per cent retreatment rate within twelve months; level of evidence 4.

- cohort
A prospective series found a soft hyaluronic acid filler improved horizontal neck wrinkles with high satisfaction and no serious adverse events.

- RCT
Adding subcision to hyaluronic acid injection improved neck wrinkle outcomes compared with injection alone in a randomised comparison.

Who it suits
Suits
Defined horizontal lines in a neck with otherwise reasonable skin; younger patients whose lines are creases rather than laxity.
Not for
Loose, crepey neck skin or heavy bands, which need tightening or muscle treatment first; anyone expecting a cream or posture change to remove established lines.
Alternatives
The two reviewed treatments most often weighed against 'Tech neck' lines, on the same standard.
| 'Tech neck' lines | HIFU | Monopolar radiofrequency | |
|---|---|---|---|
| Verdict | Established | Vetted | Vetted |
| What it is | Horizontal creases across the front of the neck, present in some people from their twenties and deepened by repeated flexion, sun and thinning skin. | High-intensity focused ultrasound delivers heat to precise points at set depths — commonly 1.5, 3.0 and 4.5 mm — creating coagulation points in the dermis and the SMAS layer that contract and stimulate collagen over months. | A single large electrode delivers radiofrequency energy that travels through the tissue to a grounding pad, heating the dermis and subcutaneous layer volumetrically. |

| Suits | Defined horizontal lines in a neck with otherwise reasonable skin; younger patients whose lines are creases rather than laxity. | Mild to moderate laxity with reasonable skin thickness, people who want a structural effect without injectables. | Mild to moderate laxity of the face, eyelids, neck and body; people who prefer a no-needle, no-injectable approach. |
| In one line | Horizontal lines, vertical bands and loose skin are three different necks; the mistake is treating all three with whatever was bought that month. | HIFU or radiofrequency is the wrong question — they do not do the same job, which is why 3D Facial Reconstruction uses both. | The device delivers heat; the protocol decides where it goes and in which order. That is the whole difference between tightening and lifting. |
Risks
Bruising, visible or palpable product along the line, Tyndall tint with superficial placement, and the neck's vascular anatomy, which makes slow, superficial technique important.
