Botulinum toxin type A softens vertical platysmal bands over about 2 weeks, with results typically lasting 3 to 4 months.
Before and after necklace lines treatment, you can expect the vertical neck bands to look softer and less pronounced, with a smoother jaw-to-neck transition. Botulinum toxin type A relaxes the platysma muscle over about 2 weeks; results are gradual and individual, not dramatic, and last around 3 to 4 months before repeating.

Necklace lines describe the visible bands and creases on the neck. The vertical cords that stand out when you tense your neck are platysmal bands, caused by the platysma muscle contracting. Botulinum toxin type A can relax this muscle, so the vertical bands appear softer and the jaw-to-neck line looks smoother in the before-and-after comparison.
It is worth being clear about what changes. Toxin treatment works best on the dynamic vertical bands that move with muscle activity; it softens their prominence rather than erasing horizontal skin creases, which are a skin-quality concern. A realistic before-and-after shows a more refined, less corded neck, not a surgical lift, and the effect is temporary.
An experienced injector matters here because the neck has structures that must be respected. Reberry Clinic treats international patients across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with the platysma assessed and injected by the clinic’s doctors and multilingual support throughout the visit.
Botulinum toxin type A works by blocking the nerve signal at the neuromuscular junction, so the platysma muscle relaxes and its vertical bands contract less. The doctor maps injection points along the visible band while you tense the neck, then places small aliquots at several sites so the toxin acts precisely where the cord is strongest. In the before-and-after, this shows as bands that stand out less and a cleaner jaw-to-neck contour, an effect sometimes described as a Nefertiti-style refinement. The change appears gradually over about 2 weeks as the muscle relaxes, and it reverses over roughly 3 to 4 months as nerve signalling returns. Accurate dosing and depth are essential in the neck, which is why an experienced injector and a careful assessment come first.

The doctor has you tense the neck to see the 1 or more platysmal bands and reviews your medical history.
Injection points are marked along each visible band, usually at several sites 1 to 2 cm apart.
A very fine needle delivers small doses at each mapped point, taking about 5 to 10 minutes.
The bands relax gradually over 2 weeks, reaching full effect by about day 14.
The result lasts around 3 to 4 months, then movement returns and treatment can be repeated.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors assess your platysmal bands and skin, then agree a tailored plan in English.
The injections take about 5 to 10 minutes, with the whole visit usually under 20 minutes.
Most patients complete treatment in 1 visit and resume activities the same day.
Softening begins within days and reaches full effect by about 2 weeks, the point most before-and-after photos reflect.
Results last about 3 to 4 months; written aftercare and an optional review support your outcome.
It shows softer, less prominent vertical platysmal bands and a smoother jaw-to-neck contour, developing over about 2 weeks. The change is refined rather than dramatic and is temporary. You can see how the treatment is planned on our botox page before comparing any images.
Necklace lines are the bands and creases on the neck. The vertical cords that appear when you tense are platysmal bands from the platysma muscle, which botulinum toxin type A can relax. Horizontal skin creases are a skin-quality concern better suited to injectable options or skin treatments.
Botulinum toxin type A relaxes the platysma muscle by blocking its nerve signal for about 3 to 4 months, so the vertical bands contract and stand out less. The doctor maps points along each visible cord while you tense the neck, then injects small doses precisely so the change looks natural in the before-and-after.
No. Toxin softens dynamic vertical bands but does not erase horizontal skin creases, which come from skin quality and aging. A realistic before-and-after shows a less corded, more refined neck rather than a fully smooth one. Combining with skin treatments can address different line types together for a fuller result.
Adults with prominent vertical platysmal bands that show on tensing are typical candidates. If your main concern is loose skin, Onda lifting or another firming option may suit better. A good clinic confirms candidacy at consultation rather than assuming toxin fits every neck concern.
Most patients feel only brief pinpricks, since a very fine needle is used and each injection lasts seconds. Numbing cream or ice can be offered for comfort. Any stinging settles immediately, so discomfort is minor and brief. Gentle technique from an experienced injector keeps the neck treatment comfortable.
Downtime is minimal, and most patients resume normal activities the same day. You may notice tiny injection marks or a small bruise on the neck that fades within a few days. A good clinic explains how to reduce bruising and what to avoid for the first few hours after treatment.
Softening usually begins within days and reaches full effect by about 2 weeks, which is when most before-and-after photos are taken. A trustworthy clinic sets this timeline upfront. If you are visiting briefly, ask for treatment early in your trip so results develop before you leave Seoul.
Results generally last about 3 to 4 months, after which the bands gradually return and treatment can be repeated. This temporary nature is normal for toxin. Pairing treatment with a skin care routine supports overall neck skin quality between sessions.
Yes, a well-run clinic can sequence toxin for the vertical bands with skin boosters or firming for horizontal creases and laxity. Volume or hydration concerns may be addressed with injectable fillers. Ask how the clinic times each step so the combined before-and-after stays balanced and natural.
Common effects include minor redness, tiny bruising, or brief tenderness on the neck that resolves within days. Because the neck has swallowing muscles, accurate dosing matters, and a careful injector minimises any temporary neck weakness. A good clinic explains these in advance and reviews your history first.
No result can be promised, because band strength, dose, skin quality, and anatomy differ between people. Before-and-after images are illustrative of individual cases, not a promise of your outcome. A good clinic sets realistic expectations at consultation, as outlined on our botox page.
Yes, at a clinic set up for international patients. Reberry Clinic provides English-language consultations across three Seoul-area locations, with multilingual support in Simplified Chinese, Traditional Chinese, Japanese and Spanish. Understanding what the before-and-after can realistically show is essential before any neck injection.
A necklace-lines visit needs only 1 to 2 days, since the appointment is quick and downtime is minimal. A clinic experienced with travellers will schedule it early so results begin before you fly. You can add a firming option such as Onda lifting at the same visit.
Yes, flying soon after treatment is generally fine, often the same day, because it is non-invasive. A good clinic advises avoiding pressure on the treated neck and staying upright during the flight. Since full results appear over about two weeks, the final before-and-after develops after you return home.
A clinic set up for international patients offers remote check-ins in English after you return home, reviewing photos as the neck result settles over two weeks. You can also explore related care such as our skin care options. Your treatment notes are kept on file for any future visit.
