Botox for vertical platysmal neck bands typically softens tenting within about 3 to 7 days, with the effect lasting roughly 3 to 4 months per session.
Necklace lines treatment in Seoul uses botox (botulinum toxin type A) injected into the vertical platysmal bands of the neck to relax the muscle so the cords soften and the neck looks smoother. Results usually appear within 3 to 7 days and last about 3 to 4 months, so most patients repeat the treatment to maintain the effect.

Necklace lines describe the vertical cords and horizontal creases that appear across the neck as the platysma muscle becomes more active and the skin loses firmness with age. The most treatable of these with botox are the vertical platysmal bands, which are the ridge-like tents you can see when you tense your neck or grimace. Botox (botulinum toxin type A) relaxes the pull of this thin, sheet-like muscle so the bands settle and the neckline looks smoother.
It is important to separate the two problems. Vertical muscle bands respond well to botulinum toxin because they are driven by muscle contraction. Horizontal necklace creases, in contrast, are often skin folds and may respond better to skin boosters, energy devices, or filler, which is why an in-person assessment matters. At Reberry Clinic, the clinic’s doctors examine your neck at rest and in motion before deciding what is realistic.
This is a non-surgical, injection-based approach with no incisions. It is well suited to international patients visiting Seoul, Korea, because the appointment is short and downtime is minimal. Our English-speaking team supports you at our operating Seoul locations (Gangnam, Myeongdong) and near Incheon Airport, so the treatment fits easily into a trip.
Botox uses botulinum toxin type A, a purified neuromodulator that temporarily blocks the release of acetylcholine at the junction between nerve and muscle. When small, precise doses are placed along the visible vertical platysmal bands, the treated portions of the platysma stop contracting as forcefully, so the cords relax and the tenting flattens. Because the platysma is a broad, superficial sheet running from the lower face down the neck, injection technique and dosing are deliberately conservative: doctors map each band, mark injection points a set distance apart, and use modest units to avoid affecting swallowing or neck strength. This is a muscle-relaxing effect, not a filler or a heat-based tightening device, so it addresses movement-driven bands rather than loose skin. The result develops gradually over several days as the muscle relaxation takes hold, and it is fully temporary, which is why the neck returns to baseline as the toxin wears off and the treatment is repeated to maintain the look.

The doctor asks you to tense your neck so the 2 or more vertical platysmal bands become visible and can be marked precisely.
Each visible band is marked with several injection points spaced roughly 1 to 2 cm apart along its length.
Small units of botulinum toxin type A are placed superficially into each band, using modest total dosing to protect swallowing and neck function.
The muscle-relaxing effect starts within about 3 to 7 days as the treated platysma stops contracting as strongly.
Peak smoothing is usually seen by about 2 weeks, when a review can fine-tune any residual band.

See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors examine your neck at rest and while tensing, confirm the bands are muscle-driven, and explain expected results in English.
The injection appointment usually takes about 10 to 20 minutes, and you can return to normal activities the same day.
A single session treats the visible bands, and any fine-tuning is typically done at a review around 2 weeks later.
Softening begins within 3 to 7 days and peaks by about 2 weeks as the platysma relaxes.
The effect lasts roughly 3 to 4 months; avoid rubbing the area for several hours and repeat treatment to maintain the look.
Necklace lines treatment softens the vertical platysmal bands of the neck using botox (botulinum toxin type A), which relaxes the muscle so the cords settle. It works on movement-driven bands rather than loose skin. You can read the fundamentals on our botox injection page before your visit.
Botox works best on vertical platysmal bands, the cords you see when you tense the neck, because they are driven by muscle contraction. Horizontal necklace creases are usually skin folds and respond better to boosters, energy, or filler. A doctor examines your neck in motion to confirm which lines will respond.
You will usually notice softening within 3 to 7 days, with the peak effect around 2 weeks after treatment as the platysma fully relaxes. This gradual onset is normal for botulinum toxin type A. A review at about 2 weeks lets your doctor fine-tune any band that needs a small top-up.
Results typically last about 3 to 4 months per session before the muscle gradually regains movement and the bands return. Duration varies with your dose, muscle strength, and metabolism. Most patients schedule repeat treatments to maintain a smoother neckline, and consistency often helps results feel more predictable over time.
Discomfort is usually mild and brief, described as small pinches as the fine needle places toxin along each band. The appointment is quick, and numbing cream can be applied for sensitive patients. Most international patients tolerate it easily and return to their day immediately, which is one reason it suits a short Seoul trip.
Downtime is minimal, and most people resume normal activities the same day. You may see tiny injection marks or slight redness that fades within hours. Avoid vigorous exercise, massage, or lying flat for a few hours. This low-downtime profile makes necklace lines treatment convenient for travellers on a tight schedule.
One session usually treats the visible bands, though a small review touch-up at 2 weeks is common to perfect the result. Because the effect is temporary, maintenance sessions every 3 to 4 months keep the neck smooth. Your doctor plans the interval around your goals and how your muscle responds.
Yes, botox for bands is often combined with skin-firming approaches when laxity is present, since the toxin relaxes muscle but does not tighten skin. Options include a Sofwave ultrasound session or a thread lift for support. Your doctor designs a layered plan matched to your neck at consultation.
No, the goal is a natural, softer neckline rather than a frozen look, achieved with conservative, band-specific dosing. Because the platysma is only partly relaxed along the treated cords, normal neck movement is preserved. Doctor-led dosing and careful placement are key to keeping the result subtle and balanced.
Most side effects are mild and temporary, such as minor redness, small bruises, or brief tenderness at injection sites. Rarely, overly deep or high dosing can affect swallowing or neck strength, which is why conservative dosing matters. Choosing an experienced doctor greatly reduces these risks. Report any swallowing change promptly for review.
Botox relaxes the muscle that creates vertical bands, while a thread lift physically supports mild sagging skin. They solve different problems: movement versus laxity. Many patients with both concerns benefit from a combined plan, which your doctor can outline based on what your neck actually needs.
Good candidates are adults with clearly visible vertical platysmal bands when the neck is tensed and no contraindications such as pregnancy or neuromuscular disease. If loose skin is your main concern, a firming Sofwave approach may suit you better. A consultation confirms the best route for your neck.
Avoid rubbing or massaging the area, strenuous exercise, and lying flat for a few hours after treatment to keep the toxin in place. Skip saunas and hot yoga that day. These simple steps help the result settle evenly. Your doctor gives tailored aftercare, and gentle skin care supports the neck between visits.
Botulinum toxin type A has a long track record in aesthetics and is generally considered safe for neck bands when dosed conservatively by a trained doctor. Contraindications include pregnancy and neuromuscular conditions. You can review the modality overview on our botox injection page and raise any health history at consultation.
A single day is often enough for the injection itself, but staying 2 to 3 days is comfortable if you want a same-trip review. Because results build over 1 to 2 weeks, many international patients treat early in their stay. Our English-speaking team helps schedule around your travel plans.
Yes, flying within a day is generally fine, as neck-band injections are minimally invasive with little downtime. Stay upright rather than reclining for a few hours before travel, and avoid rubbing the area. Cabin air is drying, so moisturise the neck. Your doctor will confirm you are ready to travel.
International patients can complete treatment in one visit and arrange remote check-ins in English if a question arises. Because maintenance is every 3 to 4 months, many plan repeat sessions around future trips to Seoul. Your treatment notes and dosing are kept on file so continuity is easy on your next visit.
