Botulinum toxin relaxes the platysma muscle behind horizontal Venus rings, so most patients see dynamic neck lines soften over about 1 to 2 weeks.
Necklace lines treatment uses botulinum toxin injected along the horizontal neck creases (Venus rings) to relax the platysma muscle that pulls the skin into folds, softening dynamic lines over about 1 to 2 weeks. Deeper static creases may also need a small booster. Patients near Hongdae (Hongik Univ.) Station are cared for at our Seoul locations with English support.

Necklace lines, often called Venus rings, are the horizontal creases that circle the neck. They form from a combination of repeated platysma muscle movement, thinning of the neck skin, and the way the neck folds during daily movement and sleep. Most people have between 1 and 4 such lines, and they tend to become more visible with age or in people who look down at screens frequently. Because the neck skin is thin and mobile, these lines can appear earlier than many facial wrinkles.
Botulinum toxin treatment softens dynamic necklace lines by relaxing the platysma, the broad, sheet-like muscle just under the neck skin. When the muscle stops pulling the skin into repeated folds, the overlying crease relaxes and smooths. A typical session takes about 15 to 20 minutes, and most patients see the lines soften over 1 to 2 weeks. For deeper static grooves that remain even at rest, the doctor may add a small hyaluronic-acid booster to smooth the crease from within, since muscle relaxation alone may not fully erase a settled line.
At Reberry Clinic, necklace-line care is consultation-led: the clinic’s doctors assess which of your lines are dynamic versus static and plan conservative dosing in English, since the neck needs careful, gentle placement. For international patients near Hongdae (Hongik Univ.) Station, this care is provided across our Seoul locations (Gangnam, Myeongdong), easily reached from 홍대입구역.
The platysma is a wide, thin muscle that stretches across the front of the neck and, when it contracts repeatedly, pulls the skin into the horizontal folds we see as necklace lines. Botulinum toxin type A works by blocking the release of acetylcholine, the chemical messenger nerves use to make the muscle contract. With the signal interrupted, the platysma relaxes in the treated zones, so the skin is no longer tugged into repeated creases and dynamic lines soften. The doctor places small, precise doses at several points along each line, usually keeping the total conservative because the neck is a mobile, sensitive area where over-treatment can affect swallowing or neck movement. This is why placement and dose are individualised rather than fixed. For deeper static creases that sit in the skin even when the muscle is relaxed, a small amount of hyaluronic-acid skin booster or filler can be layered in to lift the groove. Because the effect on the neck typically lasts a shorter time than on the face, the doctor also plans sensible maintenance intervals at consultation.

The doctor checks how many of your 1 to 4 neck lines are dynamic versus static, since only movement-related lines respond fully to muscle relaxation.
Small doses are planned at 4 to 8 points along each horizontal line, keeping the total conservative for the sensitive neck area.
Botulinum toxin type A is placed just under the skin at each mapped point, blocking the nerve signals that make the muscle pull the skin into folds.
For deeper static creases that remain at rest, 1 small hyaluronic-acid booster smooths the groove that muscle relaxation alone cannot fully erase.
Dynamic lines soften over about 1 to 2 weeks, with effects on the neck typically lasting around 3 to 4 months at first.

The clinic’s doctors assess which of your neck lines are dynamic versus static and plan conservative dosing in English, explaining what to expect.
Treatment usually takes about 15 to 20 minutes, with small injections placed at several points along each line.
Softening builds over about 1 to 2 weeks, and any booster smooths a deeper crease sooner.
Dynamic lines ease over 1 to 2 weeks, with the neck effect typically lasting around 3 to 4 months at first.
Because neck effects are shorter than on the face, maintenance every few months keeps lines soft; avoid rubbing the area for 24 hours.
It is a non-surgical procedure where botulinum toxin type A is injected along the horizontal neck creases, called Venus rings, to relax the platysma muscle that pulls the skin into folds. As the muscle stops tugging, dynamic lines soften over 1 to 2 weeks. Deeper static creases may also need a small booster, which your doctor assesses first.
Necklace lines form from repeated platysma muscle movement, thinning of the neck skin, and how the neck folds during daily movement and sleep. Most people have 1 to 4 of them, and looking down at screens often makes them more visible earlier. Whether a line is dynamic or static determines how well it responds to muscle-relaxing treatment.
Botulinum toxin blocks the nerve signals that make the platysma contract, so the muscle relaxes and stops pulling the skin into repeated creases. Dynamic lines then soften. Deeper static grooves that sit at rest may also need a booster. You can read the broader approach on our botox injection page.
Most patients see dynamic neck lines soften over about 1 to 2 weeks as the platysma relaxes, rather than instantly. Any added booster can smooth a deeper crease sooner. Your doctor may review the result at around 2 weeks to confirm the lines have eased evenly and plan the timing of your next maintenance session.
Botulinum toxin on the neck often lasts about 3 to 4 months at first, shorter than on the face, because the platysma is large and mobile. As the effect fades, the lines gradually return, so many patients plan maintenance every few months. A booster’s longevity varies by product and is discussed at consultation.
Necklace-line injections use fine needles and take about 15 to 20 minutes, with most patients reporting brief pinpricks rather than significant pain. Downtime is minimal, though tiny bruising can occasionally occur. No recovery time is usually needed, so most people return to their day right after the session at the clinic.
Not always. Fine, movement-related lines often respond well to botulinum toxin alone, while deeper static creases that remain at rest may benefit from a small hyaluronic-acid booster. Your doctor decides at consultation based on your line depth. You can compare related options on our injectable fillers page.
Neck botulinum toxin is widely performed and generally considered safe when dosed conservatively by a trained doctor, since the neck is a mobile area needing careful placement. Reviews report high satisfaction with mostly minor, technique-dependent effects. You can read our approach on the injection treatment page first.
The platysma is a large, sheet-like muscle involved in neck movement, so over-treating it can affect swallowing or neck posture. Trained doctors use small, precisely placed doses to soften lines while preserving normal function. This careful approach is why placement and units are individualised at consultation rather than applied from a fixed template.
Yes, many patients treat necklace lines alongside facial areas or a skin plan in the same visit, which is efficient for international travellers. Your doctor sequences treatments so the skin is not over-stressed. A supportive skin care routine can also help protect thin neck skin between sessions.
If your main concern is general neck laxity or crepey texture rather than single creases, energy-based skin tightening that stimulates collagen may suit you better than muscle relaxation alone. Botulinum toxin targets dynamic lines specifically. Your doctor can explain whether a combined approach with laser treatment fits your goals.
Most adults with fine, movement-related neck lines, or mixed dynamic and static creases, are suitable for a tailored plan. A consultation grades your lines and confirms whether botulinum toxin alone or a combined approach fits your neck. Very deep, purely static grooves may respond better to a booster-focused plan, which your doctor will explain clearly.
Aftercare is simple: avoid rubbing or massaging the neck, and skip saunas and intense exercise for about 24 hours, staying upright for a few hours after treatment. A gentle skin care routine helps protect thin neck skin. Your doctor provides tailored guidance and a review timeline before you leave.
Patients near Hongdae (Hongik Univ.) Station are cared for at our Seoul locations in Gangnam and Myeongdong, both easily reached from 홍대입구역 by subway. Our English-speaking team helps you choose the most convenient location and coordinate timing, so travel from the Hongdae area is straightforward for international patients.
A single day is usually enough for necklace-line treatment, since a session takes about 15 to 20 minutes with little downtime. Some patients add a day to combine facial or skin treatments. Our English-speaking team helps schedule your visit efficiently around your travel plans from Seoul or the wider area.
Yes, flying within a day is generally fine because necklace-line injections are minimally invasive with little downtime. Avoid rubbing the neck and stay upright for a few hours afterward. Results continue developing over the following 1 to 2 weeks, so you will keep seeing the lines soften after you return home.
International patients can complete a session in a single visit, and the clinic offers remote check-ins in English as the effect settles over 1 to 2 weeks. Because results last months, many patients plan a maintenance session on a future trip. Your treatment notes are kept on file for continuity between visits.
