Hello! This is Seye Clinic, embracing all the beauty in the world.
If you are bothered by horizontal neck lines and want a smoother, more youthful neck, several non-surgical treatments can help. At Seye Clinic in Gangnam, Seoul, we commonly use Belotero Soft filler for immediate improvement, often complemented by Radiesse Neck and neck skin botox for firmness and surface refinement. Most procedures require minimal downtimeâtypically 0â1 dayâwith results visible as soon as the same day for HA filler.
A week rarely goes by without a patient showing me their neck and asking, "Can you do anything about these lines?" Horizontal neck linesâsometimes called "necklace lines"âare those persistent, horizontal creases that develop across the neck, often well before other signs of aging appear.
Horizontal neck lines are shallow-to-deep creases that run laterally across the neck. They form as a result of repeated bending and movement, compounded by the natural thinning of neck skin, loss of elasticity, genetics, and environmental exposures. Mobile screens and "tech neck" posture have also contributed to an increase in these concerns among younger patients.
The neck is a delicate areaâits skin is thinner and more mobile than the face, meaning itâs more vulnerable to the effects of skin laxity, collagen loss, and repetitive motion. Unlike facial expression lines, which are often dynamic (forming with movement), neck lines tend to be "static," visible regardless of expression. Over time, gravity, sun exposure, and the natural drop in collagen and elastin deepen these lines and make the skin appear crepey or saggy.
A common scenario we see: a young professional in their early 30s, otherwise youthful, who is surprised by developing deep lines on the neck. Many worry about treatments looking obvious or lumpyâespecially in such a visible, thin-skinned area. Our approach focuses on natural, non-bulky rejuvenation.

In our clinical practice, no two necks are the sameâtreatment is always a blend of tailored solutions. Here are the primary options we offer:
Treatment | What It Does | Best For | Duration | Downtime | Certification |
|---|---|---|---|---|---|
Belotero Soft | Instantly fills deep or superficial horizontal lines with soft HA | Filling visible grooves in thin skin | 6â12 months | 0â1 day | MFDS, FDA |
Radiesse Neck | Boosts collagen/elastin via CaHA, firms & smooths texture | Improving neck skin quality & firmness | Gradual, weeksâmonths | 0â1 day | MFDS, FDA |
Neck Skin Botox | Smooths fine lines, surface firmness with micro-toxin injections | Crepey texture, incipient fine lines | 2â6 months | 0â1 day | MFDS, FDA, CE |
Belotero Soft: We use small, precisely placed injections of this soft hyaluronic acid filler to blend naturally into shallow or deeper neck lines. The CPM technology prevents lumpiness or a "pillow" look. Because the neck is thin-skinned, only this gentle, cohesive matrix is appropriateâthe result is nearly invisible to touch, yet immediately softens the groove. Amount injected varies (in cc units, not "shots"), determined by the depth and length of the lines.
Radiesse Neck (Hyperdiluted CaHA): If your primary concern is crepey, thinned, or sagging neck skin, we may suggest Radiesse Neck, which is diluted and spread across wide areas. Unlike facial Radiesse (focused on volume), this protocol does not volumizeâinstead, it sends CaHA microspheres into the dermis, triggering your skinâs own collagen and elastin production. Improvement is gradual, appearing over weeks to months, and strengthens the skin around and between the lines.
Neck Skin Botox: For fine lines and rough surface textureâespecially the subtle, crepey wrinkling that doesn't respond to fillingâmicro-droplet intradermal botox softens the surface and boosts perceived firmness. Injected very shallowly (in "units," not cc), it doesnât alter muscle movement or expression.
Many patients benefit from a combination: Belotero Soft to fill the deepest horizontal grooves, Neck Skin Botox for fine lines and smoothness, and Radiesse Neck for overall support, elasticity, and long-term improvement. For each treatment, the downtime is usually 0â1 day, so you can return to your usual activities by the next day.
After performing hundreds of these treatments, we know that most patients worry about three things: will it look natural, how painful is it, and how long will it last? Hereâs how we guide our patients:
In our clinical experience, combination treatment yields the smoothest and most natural outcome, yet is always tailored. We recommend a consultation to evaluate your linesâ depth, skin thickness, and treatment history.
When considering neck rejuvenation in Seoul, Gangnam stands out for both medical innovation and patient trust. At Seye Clinic, located just a 1-minute walk from Gangnam Station, patients receive expert guidance from our KOL (Key Opinion Leader) doctorsâexperienced clinicians who regularly train others in non-surgical neck rejuvenation.
What sets Seye Clinic apart? We are recognized as a Certified Re2O Key Clinic and an Alltite Research Advisory Hospital, reflecting our ongoing clinical participation with global injectables. For horizontal neck lines, we use only FDA- and MFDS-approved products like Belotero Soft and Radiesse Neck, ensuring every ingredient and technique is fully documented and authentic.
Our facility is designed in cool gray and white tones, resembling an Apple Store in both atmosphere and hygiene. Every injection is performed under precise daylight lighting, making natural blending of fillers easier to judgeâa small, but critical factor only those who work extensively with thin neck skin truly appreciate.

Your experience at Seye Clinic always begins with a comprehensive consultationâour doctor takes time to examine your neck profile, assess line depth, skin elasticity, and overall texture. We discuss your specific concerns and map out a tailored plan (often combining approaches for best effect).
As an MFDS- and FDA-approved advanced injectables clinic, your safety and satisfaction are our priorities. What makes Seye unique is our ultra-modern, minimal environment and our focus on comfort, subtlety, and authentic product choiceâa difference our patients can see and feel from consultation to results.
Q: How long do Belotero Soft results last for neck lines?
Results after Belotero Soft treatment for horizontal neck lines typically last 6 to 12 months. The exact longevity can vary based on your skin type and neck movement. Maintenance sessions can extend the effect as needed.
Q: Will filler make neck lines look lumpy or unnatural?
Belotero Soft uses CPM technology that ensures the filler spreads smoothly into thin, mobile neck areas. This reduces any chance of bumps, resulting in a natural look and feel. We inject in small, controlled amounts for an even finish.
Q: How soon can I return to daily activities after treatment?
Most patients experience 0 to 1 day of downtime, meaning you can usually resume normal life immediately or the next day. Some redness or swelling may occur but usually fades within hours.
Q: Can I combine Belotero Soft, Radiesse Neck, and skin botox in one session?
Yes, many patients benefit from a combination approach. Our doctor evaluates the linesâ depth and skin quality to determine your ideal sequence. Using multiple modalities can enhance overall neck smoothness and skin texture.
