Neck Lines and 'Tech Neck' Lines: Causes and Prevention

Neck lines, the horizontal creases across the front of your neck, come from a mix of natural skin folds, gradual collagen loss with age, sun exposure and genetics, and repeatedly looking down may add to them. You can’t stop them forming entirely, but you can look after the skin with daily sunscreen and moisturiser, use retinoids carefully, and build posture habits that fold the neck less often. Below you’ll find what’s known about “tech neck” lines, practical prevention habits, a short neck skincare routine and gentle neck exercises.

What causes neck lines

Most neck lines are where the skin naturally folds, and age, sun and genetics decide how visible those folds become. The front of your neck bends every time you look down, nod or turn your head, so the skin has to crease somewhere. Several things shape how visible they become:

• Natural skin folds. Many people have one or two horizontal lines from a young age. They’re partly anatomical, much like the creases on your wrist.
• Collagen loss with age. Over the years skin becomes thinner, drier and less elastic, so folds that once smoothed out straight away start to linger.
• Sun exposure. UV light is one of the main drivers of premature skin aging, and the American Academy of Dermatology lists sun protection first among its everyday ways to reduce it (AAD). The neck often gets the sun but skips the sunscreen.
• Genetics. Skin type, neck length and soft tissue vary, so two people with similar habits can have very different necks.
• Repeated bending. Folding the skin in the same place many times a day may contribute over the years, the same way expression lines form on the face.

If what bothers you is loose skin or vertical bands under the chin rather than horizontal creases, that’s a different picture. Our guide to turkey neck exercises covers skin laxity and platysma bands.

Are “tech neck” lines real?

“Tech neck lines” is a popular name for horizontal neck creases, and phone use is a plausible contributor, but nobody has measured how much it adds. Looking down at a screen folds the front of the neck exactly where these lines sit, so the idea makes sense.

What we can say honestly:

• The folding is real. Bending your head forward creases the front of the neck, and many of us now hold that position for hours a day.
• The size of the effect is unknown. There’s no good study showing how much screen posture contributes to tech neck wrinkles compared with age, sun and genetics. Claims that phones are the main cause go beyond the evidence.
• Early lines aren’t proof of phone damage. People had neck creases long before smartphones.

Posture and screen habits are worth working on mostly for comfort: a forward head puts more load on the neck. Our guide on what tech neck is explains the strain side in detail.

Prevention habits for everyday life

The habits most likely to help are the ones that cut down how long your neck stays folded and how much sun it gets. None guarantees fewer lines, but they’re low-effort.

• Bring your phone up. Hold it closer to eye level and lower your eyes rather than your whole head.
• Raise your screens. Set the top of your monitor roughly at eye level.
• Take short breaks. Every 30 to 60 minutes, look up, roll your shoulders and do a few chin tucks. A phone reminder helps.
• Check your sleep position. A review of “sleep wrinkles” describes how pressing your face into a pillow when you sleep on your side or stomach compresses and distorts the skin, and suggests this may add to aging over time (Anson et al., 2016). The paper looked at the face, not the neck, so treat this as a reasonable idea rather than a proven cause. Sleeping on your back is a fine choice if it’s comfortable; if not, comfort comes first.

For a full desk routine, see our tech neck exercises, which focus on the neck, shoulders and upper back.

Neck skincare: SPF and moisturiser

The most useful thing you can do for neck skin is treat it exactly like your face: sunscreen every morning and moisturiser every day.

• Sunscreen down to the chest. The AAD recommends a broad-spectrum sunscreen with SPF 30 or higher on all skin not covered by clothing (AAD). In a randomised trial in Australia, adults under 55 who used sunscreen every day showed no detectable increase in skin aging over four and a half years, measured on the backs of the hands (Hughes et al., 2013).
• Moisturiser. Smooth it on from collarbone to jaw. Hydrated skin looks smoother and lines look softer for a while, even though firmness doesn’t change.
• Retinoids, with care. Retinoids and retinol are among the best-studied anti-aging skincare ingredients, but they can cause dryness, redness and irritation (AAD). Neck skin is thinner and often more sensitive than facial skin, so start with a pea-sized amount spread thinly a few nights a week, follow with moisturiser and pause if it stings or peels.
• Gentle application. Use light strokes, not tugging, and cover the front and sides.

Our morning skincare routine shows where sunscreen goes, and Gluvy’s skincare lessons include a guide on how to use retinol.

Neck exercises and stretches

Neck exercises won’t smooth neck lines, but they may help you hold your head more neutrally, ease tension and relax the muscles at the front of the neck. Sit or stand tall with your shoulders relaxed and move slowly. Keep every movement small; there’s no need to push the head far back.

1. Chin Tuck (about 40 seconds)

1. Sit tall with your eyes level.
2. Without nodding down, glide your chin straight back as if making a double chin on purpose.
3. Hold for about 5 seconds, feeling the back of the neck lengthen.
4. Release and repeat 5 or 6 times.

Common mistake: tipping the head down instead of sliding it back. Keep your eyes on the horizon.

2. Shoulder Roll and Drop (about 30 seconds)

1. Breathe in and lift both shoulders toward your ears.
2. Roll them back and let them drop as you breathe out slowly.
3. Repeat 5 times, letting your jaw soften and your teeth part slightly.

3. Side Neck Tilt (about 45 seconds)

1. Keep both shoulders low.
2. Tilt your right ear toward your right shoulder until you feel a gentle stretch along the left side of your neck.
3. Hold for 3 or 4 slow breaths without pulling with your hand, then switch sides.

Common mistake: lifting the shoulder to meet the ear.

4. Soft Front-of-Neck Release (about 40 seconds)

1. Rest your fingertips lightly on your collarbones.
2. Relax your jaw, then lift your gaze slightly, just enough to look at where the wall meets the ceiling, and smile gently with closed lips.
3. Hold for 3 breaths, feeling a mild stretch down the front of the neck, then return to level.
4. Repeat 3 times.

Common mistake: throwing the head back. A small tilt is enough.

Safety: stop any move that causes pain, dizziness, or tingling or numbness in your arms. If you have a neck condition, a recent injury, or recent surgery or injectables in the area, check with a doctor or physiotherapist first. More neck and jaw moves are in our guide to jawline exercises, and you can follow chin, jaw and neck sessions on video in the chin and jawline programs.

Gentle neck massage

A light neck massage can feel relaxing and pairs well with applying moisturiser, but it doesn’t change the lines themselves. Keep the pressure feather-light and avoid pressing on the front of the throat.

With a little oil or moisturiser, stroke from under your jaw down the sides of the neck toward the collarbones, a few times per side. Barely touch the centre of the front of the neck, never press on the pulse point, skip irritated skin, and check with your doctor first if you have a thyroid condition. If you use a stone, our gua sha neck routine shows where to stroke and where not to press.

Professional options

If neck lines bother you, a board-certified dermatologist can explain in-office options and whether they suit your skin. These are medical treatments carried out by licensed clinicians, with their own costs, risks and recovery, and they are different things from exercise or skincare. Depending on the person, options discussed may include prescription-strength retinoids, chemical peels, laser or other energy-based treatments, and injectable treatments. None of these replaces daily sun protection.
