You may have noticed faint horizontal creases forming across your neck — often called necklace lines or “tech neck” wrinkles. While they’re a natural part of aging, lifestyle and posture can play a big role in how early they appear.
What Causes Necklace Lines?
Necklace lines form when collagen and elastin — the fibers that keep skin firm — start to break down. The main culprits include:
Aging: Natural loss of collagen makes skin thinner and less elastic.
Tech neck: Constantly looking down at phones or laptops can deep skin folds.
Sun damage: UV rays accelerate aging and weaken skin structure.
Dehydration & lifestyle: Smoking, poor hydration, and lack of skincare speed up neck lines.
Because neck skin is thinner and often neglected, it’s especially prone to these folds.
Best Treatments for Necklace Lines
Whether your lines are fine or deep, there are effective solutions:
✨ At-Home Care:
Apply SPF daily (extend sunscreen to your neck and chest).
Use retinol or peptide creams to boost collagen.
Hydrate with hyaluronic acid serums to smooth and plump skin.
💎 In-Clinic Options:
Microneedling / RF microneedling – stimulates new collagen.
Dermal fillers – soften deeper horizontal lines.
Botox – reduces neck muscle tension and dynamic lines.
Laser or ultrasound therapy (e.g. Ultherapy) – tightens and rejuvenates.
Combination treatments often deliver the best, most natural results.
How to Prevent Necklace Lines
Keep screens at eye level to avoid “tech neck.”
Moisturise and protect the neck daily — treat it like your face.
Stay hydrated and use antioxidant-rich skincare.
Sleep on a low pillow to minimise overnight creasing.
Final Thoughts
Necklace lines are common but completely manageable. With a consistent skincare routine, good posture, and personalised aesthetic treatments, you can maintain a smoother, firmer neckline for years to come.
