If your neck wrinkles look deeper or more noticeable than the wrinkles on your face, there is a reason: neck skin is structurally different from facial skin and is exposed to constant movement.
That is why treating the neck should not simply mean extending your facial skincare routine downward. A dedicated neck treatment can provide more targeted coverage and 660nm red light is one technology that may help improve the skin changes behind visible neck wrinkles.
Is Neck Skin Different From Facial Skin?
Neck skin has distinct structural and biomechanical characteristics. Research comparing neck and cheek skin found that neck skin has a thinner dermal layer and greater extensibility than facial skin. Constant movement and sun exposure may also contribute to the formation of neck wrinkles.
A 2024 review on neck aging found an even more striking difference: neck skin is about 80% as thick as cheek skin, has approximately three times the extensibility, and neck wrinkles can reach approximately five times the depth of cheek wrinkles.
The neck also undergoes constant movement as you turn, bend, and extend your head, while receiving regular sun exposure. These factors may contribute to the development of visible signs of neck aging.
So if your neck lines are deeper or more pronounced than your facial wrinkles, treating the neck as a distinct area makes sense.
Why Can JOVS 660nm Red Light Help Neck Wrinkles?
660nm red light has been studied for its effects on skin. Research on 660nm LED photobiomodulation has reported changes in collagen-related markers, including increased type-I procollagen and reduced MMP-1. Clinical studies have also reported improvements in wrinkle appearance and skin texture after repeated treatments.
For the neck, the way the light reaches the skin is another practical consideration. A device that sits directly against the skin keeps the light source close to the treatment area, avoiding the extra distance between the LEDs and the skin that occurs with handheld or freestanding light sources.
The JOVS Red LED Light Neck & Chest Mask for neck wrinkle care uses 66 LEDs emitting 660nm red light, with a reported irradiance of 67.26 mW/cm². Its flexible design wraps around the neck and chest so the LEDs remain close to the skin during treatment.
There is also clinical evidence specifically for LED treatment of neck wrinkles. In a randomized, double-blind, sham-controlled trial involving 70 participants, a home-use neck device using 630nm LED and 850nm infrared light produced significantly greater improvements in investigator-assessed wrinkle scores than the sham device at Weeks 8, 12, and 16.

Red light therapy is most relevant to wrinkles associated with skin aging, collagen loss, reduced elasticity, and photoaging.
Fine neck lines
Fine, superficial lines are among the most suitable targets for red light therapy. Improving overall skin quality may make these lines appear less noticeable over time.
Early horizontal neck lines
Early horizontal lines can be influenced by both skin aging and repeated neck movement. Red light may help improve the skin component of these lines, particularly when they are still relatively superficial.
Photoaging-related wrinkles
UV exposure contributes to collagen degradation and visible skin aging. For photoaged neck skin, red light therapy can be used as part of a broader anti-aging routine alongside daily sun protection.
Which Neck Wrinkles Are Hard to Treat With Red Light Alone?
Red light therapy cannot directly remove every type of neck wrinkle.
Deep, fixed neck folds
If a wrinkle is deeply etched into the skin and remains highly visible even when the neck is relaxed, red light alone is unlikely to erase it. It may improve the surrounding skin's quality, but it does not physically fill a deep fold.
Platysmal bands
Vertical bands that become prominent when the neck muscles contract are related to the platysma muscle rather than simply the surface quality of the skin. Red light is therefore not a direct treatment for prominent platysmal bands.
Significant skin laxity
Red light may support skin quality and firmness, but it cannot reposition or remove significant excess skin.
Conclusion
Red light therapy may help improve the appearance of neck wrinkles, particularly fine lines and early signs of photoaging. Studies of 660nm red light have reported improvements in wrinkles and skin texture, with some evidence of increased collagen production.
