The neck is often one of the first areas to show visible signs of aging, yet it is frequently overlooked in aesthetic consultations. The primary culprit behind those vertical cords that appear along the front of the neck—often called "platysmal bands"—is the platysma muscle. Botox Injections in Riyadh (حقن البوتوكس في الرياض) This broad, thin sheet of muscle extends from the collarbones up over the jawline, blending into the lower face. Over time, its repeated downward contraction can create visible bands and blur the once-sharp jawline, contributing to a tired or aged appearance.

The FDA Approval: A New Standard of Care

A significant milestone in non-surgical neck rejuvenation occurred in October 2024, when BOTOX® Cosmetic received FDA approval for the temporary improvement of moderate to severe platysma bands . This was a landmark decision, making it the first neurotoxin approved for this specific indication and providing an evidence-based, non-surgical intervention for an area that had long been a therapeutic gap . The approval was supported by pivotal clinical trials that demonstrated significant improvements in the appearance of platysma bands at day 14, with a multi-component ≥2-grade improvement seen in 32% of treated patients versus 2% with placebo .

How the Treatment Works

The treatment targets the dynamic muscular forces that drive visible banding and jawline blunting. By strategically relaxing the platysma muscle, the downward pull is weakened, allowing the lifting muscles of the midface to regain the advantage . This rebalancing of forces softens the appearance of vertical neck cords and can create a cleaner, more defined jaw-neck angle, often referred to as a "Nefertiti lift" . It is a refinement, not a facelift; the change is measured in millimeters, but the effect on overall appearance can be significant.

Injection Technique: A Modern, Anatomical Approach

The traditional approach to treating the platysma often involved many superficial injections across the entire muscle. However, recent research has revolutionized this technique. A 2025 study in the Journal of Cosmetic Dermatology mapped the motor innervation of the platysma and found that motor end-plates are clustered in the upper half of the muscle, while the lower third is largely innervated by sensory nerves . This means injections in the lower platysma provide minimal therapeutic benefit and may increase the risk of complications, such as weakening neck support muscles .

Ultrasound guidance is increasingly recommended to ensure precise targeting in the subdermal or subplatysmal plane, avoiding intradermal deposition which can increase bruising and immune sensitization . This targeted approach can reduce the number of injection points and total dose by up to 50% while achieving equivalent clinical results . A study implementing this neural distribution-based protocol found that 92.5% of patients achieved a ≥2-grade reduction in dynamic bands by week 4, with a 35% reduction in toxin use and a drop in bruising to just 5% .

What Results to Expect

The effects of neck Botox are not immediate. Results begin gradually and are typically most apparent after 10 to 14 days . In many patients, the effect lasts around 3 to 4 months, with strong platysma activity potentially shortening this duration . While some may experience a longer effect, maintenance is commonly needed two to three times per year to sustain the improvement . It is important to note that Botox treats muscle, not skin. If the primary concern is loose, sagging skin or significant submental fullness, this treatment may not be the right solution, and other modalities like skin-tightening treatments or surgery should be considered .

Combining with Other Aesthetic Treatments

A comprehensive approach to neck rejuvenation often involves more than just Botox. For patients with significant skin laxity, a combination with energy-based devices, dermal fillers for volume loss, or skin-quality treatments like skinboosters may be recommended for optimal results . An honest, holistic assessment is key to determining the best individualized treatment plan.

Frequently Asked Questions

How long do neck Botox results last?

In many patients, the effect lasts around 3 to 4 months, though strong platysma activity may shorten the duration .

When will I see results?

Results begin gradually and are usually easier to judge after 10 to 14 days following the treatment .

Is the Nefertiti lift the same as surgery?

No. It is a non-surgical Botox technique that works best for mild to moderate muscle-related neck and jawline changes .

What are the risks of treating platysma bands?

Specific risks include dysphagia (difficulty swallowing), neck weakness, and aesthetic asymmetry, which is why a deep understanding of anatomy is crucial .

Can Botox alone fully rejuvenate the neck?

Sometimes, if platysmal activity is the main issue. However, many patients need a combination plan because lines, laxity, and texture often come from multiple causes .
