Horizontal necklace lines are softened with micro-dose botulinum toxin, often alongside skin boosters, over a plan whose effect commonly lasts around 3 to 4 months per toxin session.
Necklace lines, the horizontal creases across the neck, are treated in Gangnam, Seoul with micro-dose botulinum toxin to relax the underlying muscle, often combined with skin boosters or resurfacing for the skin itself. Because the right mix depends on your line depth and skin, the clinic’s doctors confirm a tailored plan at consultation rather than a fixed formula.

Necklace lines are the horizontal creases that run across the front of the neck, sometimes called neck rings. They form from a mix of repeated neck movement, the pull of the underlying platysma muscle, natural collagen loss, sun exposure, and increasingly from looking down at phones. Because more than one factor is usually involved, the most effective plans treat both the muscle component and the skin quality, rather than relying on a single tool.
For the muscle-driven part, small, precisely placed micro-doses of botulinum toxin relax the fibres that deepen the horizontal creases, softening how prominent the lines look. For the skin itself, skin boosters that hydrate and stimulate collagen, or gentle resurfacing, improve texture and fine lining. A doctor decides the balance based on how deep your lines are, how much is muscle versus skin, and your overall neck condition. Toxin effects on the neck are subtle and temporary, commonly lasting around 3 to 4 months per session.
At Reberry Clinic, necklace-line care is consultation-led. Dr. Yoongon Ryu and the clinic’s doctors at our Gangnam (Seoul) location, on Gangnam-daero about 2 minutes from Gangnam Station exit 10, assess your neck lines and skin, then build a tailored plan and explain the cost transparently in English. International patients are supported across our three Seoul-area locations, so care can fit your travel schedule.
Necklace lines have two components that a good plan addresses separately. The first is muscular: the platysma and fine neck muscles pull on the skin and deepen the horizontal creases with movement. Micro-doses of botulinum toxin type A, placed superficially along the lines, temporarily reduce that muscle pull by blocking the nerve signal to the treated fibres, so the creases look softer and less etched. Doses on the neck are deliberately small and carefully mapped, because the neck muscles are involved in normal function, and the aim is refinement rather than heavy weakening. The second component is the skin itself: collagen loss, dehydration, and sun damage make the lines more visible regardless of muscle. This is where skin boosters, which deliver hydrating and collagen-stimulating ingredients into the dermis, or gentle resurfacing, improve texture and fine lining over a series of sessions. Because these two parts work on different problems, plans often combine them, sequenced so the skin is not over-stressed. Toxin effects are temporary, commonly lasting around 3 to 4 months per session, while skin-quality improvements build gradually over weeks, which is why the doctor plans a course and reviews progress rather than promising a single permanent result.

Doctors judge how much of your necklace lines is muscle-driven versus skin quality, which shapes the balance of the 2 main approaches used.
If muscle pull is a factor, small micro-doses of botulinum toxin are placed along the horizontal lines, spaced about 1 to 1.5 cm apart.
Skin boosters or resurfacing are added over a series of 2 to 4 or more sessions to improve texture and fine lining in the neck skin.
Treatments are staged over several weeks so the skin is not over-stressed, and the doctor reviews progress between the 2 or more visits to adjust the plan.
After assessment, the clinic’s doctors give you a transparent, individualised plan and cost in English rather than a single fixed formula.

At our Gangnam (Seoul) location, the clinic’s doctors assess your neck lines and skin, then explain which approaches your plan needs and what drives the cost, in English.
A micro-dose toxin session usually takes about 15 to 20 minutes; skin-booster or resurfacing sessions vary by the area treated.
Skin-quality care runs as a course, so cost is mapped across a series rather than a single fixed visit, while toxin is repeated periodically.
Toxin softening appears over about 1 to 2 weeks, while skin-quality improvements build over several sessions across weeks.
Because toxin lasts roughly 3 to 4 months, repeat sessions and sun protection help maintain results, which is factored into long-term planning.
Necklace lines are treated with micro-dose botulinum toxin to relax the muscle pull that deepens the horizontal creases, often combined with skin boosters or gentle resurfacing for the skin itself. The right mix depends on your lines, so a doctor tailors it at consultation. You can start on our botox injection page.
Necklace lines form from a mix of repeated neck movement, the pull of the platysma muscle, natural collagen loss, sun exposure, and increasingly from looking down at phones. Because more than one factor is usually involved, the most effective plans address both the muscle and the skin quality rather than relying on a single treatment.
Yes, micro-doses of botulinum toxin can soften horizontal necklace lines by relaxing the muscle fibres that deepen the creases with movement. A study of horizontal neck lines using about 15 to 30 units reported clinical improvement with high satisfaction. It works best when the lines have a muscle component, which your doctor assesses at consultation.
Botulinum toxin effects on the neck are temporary, commonly lasting around 3 to 4 months per session, so it is not a one-time fix. Skin-quality improvements from boosters or resurfacing build cumulatively with a maintained series. Your doctor plans repeat sessions and reviews progress so results are sustained over time. See our botox injection page.
Because necklace lines are part muscle and part skin, combining approaches usually works better than one alone. Toxin softens the muscle-driven creases, while skin boosters hydrate and stimulate collagen in the neck dermis. Comparative studies suggest combined plans improve neck lines more than toxin alone, which is why a doctor often sequences both over a course.
Skin boosters are often included when your neck skin is dehydrated or crepey, since they deliver hydrating and collagen-stimulating ingredients into the dermis over a series of sessions. Whether they are needed depends on your skin quality, assessed at consultation. You can explore related options on our Rejuran Healer page.
Discomfort is usually mild for micro-dose toxin, which uses fine needles, and comfort measures are available for booster or resurfacing sessions. The neck can feel a little sensitive during injections. Your doctor explains what to expect for each part of your plan beforehand, so you are comfortable with the process before starting any session.
Toxin softening usually appears over about 1 to 2 weeks as the muscle relaxes, not immediately. Skin-quality improvements from boosters or resurfacing build more gradually over several sessions across weeks. Your doctor reviews progress between visits so the plan stays matched to your response rather than promising an overnight change to your neck lines.
Doses on the neck are deliberately small and carefully mapped, because the neck muscles are involved in normal function, so the aim is subtle refinement rather than heavy freezing. A skilled doctor balances softening the lines with preserving natural movement. This is why technique and assessment matter more than dose alone for a natural-looking result.
Necklace lines are softened and improved rather than erased in a single visit, especially deeper, long-standing lines with a skin component. A combined, maintained plan gives the best gradual improvement. Your doctor sets realistic expectations at consultation so you understand what degree of change is achievable for your particular neck and skin.
Cost depends on which approaches your plan combines, the units of toxin, and how many booster or resurfacing sessions are needed, so there is no single fixed price. A good clinic explains this at consultation. See our injectable fillers page; the doctors confirm your individualised cost after assessment.
Most adults with mild to moderate horizontal neck lines are suitable, particularly if the lines deepen with movement or the skin is dehydrated. A consultation determines how much is muscle versus skin. Deeper structural laxity may need a firming approach like our skin care page, which your doctor explains upfront.
Common effects are usually mild and temporary, such as injection-site tenderness or brief marks. Because the neck muscles support normal function, precise dosing by an experienced doctor limits any temporary heaviness sensation. Your doctor reviews your health and medications first and explains what to watch for as part of a careful, individualised assessment.
People who are pregnant or breastfeeding, have certain neuromuscular disorders, active neck-skin infection, or a known allergy to botulinum toxin or booster components should not be treated without careful review. A consultation checks your history and medications first, and your doctor confirms whether a necklace-line plan is suitable and safe for you.
For a first session, 2 to 3 days is comfortable, allowing a consultation, treatment, and a short review. Because skin-quality care runs as a course and toxin is repeated, many international patients begin at our Gangnam location and continue on return visits. Our English-speaking team helps coordinate timing and cost around your travel.
Yes, flying within a day or so is generally fine for micro-dose toxin and most booster sessions, which are minimally invasive. Avoid rubbing the treated neck and follow simple aftercare. If you had resurfacing, your doctor advises on sun protection and care while you travel. Follow-up from abroad can be arranged in English.
International patients can plan repeat toxin and booster sessions around trips to Seoul, and the clinic offers English follow-up between visits so the plan stays on track. Your treatment notes are kept on file for continuity. You can also explore related neck and skin options on our injection treatment page beforehand.
