Dermatologists have a clinical name for tech neck: forward head posture, or FHP, and it is producing horizontal neck creases in patients young enough to include children.

"It's an acquired postural problem where the head sits abnormally forward in comparison to the shoulders," explains Fort Worth, TX dermatologist Kathryn "Celeste" Durham, MD. Over time, the repeated strain surfaces on the skin as horizontal lines — known as Venus rings or tech neck wrinkles.

The mechanism is the same one behind the "11s" between the brows. Omaha, NE dermatologist Joel Schlessinger, MD compares the two: every downward glance folds the neck skin in the same spot, and eventually the crease becomes permanent.

How to tell tech neck from aging

Direction is the diagnostic clue, according to Dr. Durham. Tech neck lines run straight across the neck and sit on a single plane. Regular aging, by contrast, shows up as crepey, loose skin. Dr. Schlessinger adds that the earliest signs are small, faint wrinkles that deepen over time.

What causes it

Looking down at phones and laptops is the trigger, but not the only one. Dr. Durham points to photoaging — sun damage — as a contributing factor, along with blue light. She is precise on the evidence: there is no strong proof that device blue light causes free-radical damage on its own, but it adds to the blue light already coming from the sun and other sources. Because collagen declines naturally with age, skin loses its ability to bounce back from repeated folding.

Tension plays a role as well. Dr. Durham says tightness in the upper neck and head can worsen tech neck, and it can even contribute to kyphosis, an exaggerated curve of the upper back.

Prevention

Dr. Durham's first-line advice is ergonomic: raise the computer to proper height and lift the phone closer to eye level, so the head is not dropping with every notification.

On the light-exposure front, she suggests adding a blue light filter to devices as an extra precaution. Sunscreen is the nonnegotiable. She recommends a daily mineral formula to shield skin from UV rays — the biggest collagen culprit — and notes a tinted version adds protection against visible light. That application must include the neck.

Topical treatments

Dr. Durham recommends retinoids, such as tretinoin, to rebuild collagen. For a neck-specific product, Dr. Schlessinger points to his own LovelySkin LUXE Firming Peptide Neck Cream ($110), which contains several peptide types, including palmitoyl tripeptide-1, plus acetyl dipeptide-1 cetyl ester to calm the skin's inflammatory response. His caveat: topicals alone will not erase deeper creases.

In-office treatments

For deeper lines, the pros take over. In-office treatments can help "tremendously," says Dr. Durham. Hyaluronic acid fillers plump the lines from underneath. Neurotoxins — Botox Cosmetic, Xeomin, Dysport and Jeuveau — relax the platysma, the thin muscle running along the neck, softening the lines' appearance.

Anything that boosts collagen helps, so Dr. Durham also favors microneedling with PRP (platelet-rich plasma) to smooth lines and strengthen surrounding collagen. Where loose skin or sun damage accompanies the creases, radiofrequency microneedling and fractional lasers can address both.

The results are temporary

No tech neck treatment lasts. Results from neurotoxins and lasers are temporary, Dr. Schlessinger says, and constant phone and tablet use will undo them.

Both dermatologists take a long-game approach. Dr. Schlessinger stresses prevention as a huge part of improvement. Dr. Durham relies on daily sunscreen and retinoids to protect and rebuild collagen between appointments, with microneedling and lasers strengthening the skin itself. The best results come from pairing the two: treat the lines, then change the habit that put them there.
