What are neurotoxins?

Neurotoxins are prescription medicines used by licensed professionals to soften dynamic lines—the expression lines that appear with frowning, squinting, or raising your brows. They work by temporarily blocking the nerve signals that make targeted muscles contract.

They do not add volume (that’s a job for dermal fillers) and won’t resurface skin texture like peels or lasers. Think of neurotoxins as a way to quiet overactive movement for a smoother, more relaxed look.

Where they help (and where they don’t)

• Common targets: glabellar “11s,” forehead lines, crow’s feet, bunny lines, chin dimpling.
• May help: jawline slimming (masseter), gummy smile, neck bands — always pro-only.
• Don’t expect: added volume, lifted cheeks/lips, or scar smoothing — those need other modalities.

Onset & longevity — what’s typical?

• Onset: light softening in 2–5 days, peak at 10–14 days.
• Longevity: usually 3–4 months. Some people experience a shorter or longer window.

What impacts your results?

1. Dose & placement: Adequate units and precise mapping by a licensed pro are critical.
2. Muscle strength & movement patterns: Stronger muscles may need more units and can wear off faster.
3. Metabolism & lifestyle: High activity levels and fast metabolisms may shorten duration.
4. Skin quality & age: Etched static lines may still show; pair with skincare and sun protection.
5. Aftercare: Rubbing the area, intense workouts, or heat exposure too soon can affect outcomes.
6. Product & authenticity: Always ensure products are authentic and appropriately handled.

Smart aftercare (first 24–48 hours)

• Avoid rubbing or massaging treated areas; keep makeup gentle and minimal at first.
• Skip saunas, hot yoga, facials, and strenuous workouts for 24 hours.
• Stay upright for at least 4 hours post-treatment.
• Use daily SPF 30+ and focus on a simple, soothing routine.

Safety notes

Neurotoxin treatments must be performed by licensed professionals using authentic products, following local laws and medical guidance. Avoid treatment if you are pregnant, breastfeeding, or have certain neuromuscular conditions—discuss your medical history with your provider. Seek medical care promptly if you experience unexpected side effects.

Key takeaways

• Best for expression lines; not a volumizer or resurfacing treatment.
• Expect results in 2–14 days, with typical longevity of 3–4 months.
• Outcomes depend on dose, placement, muscle strength, metabolism, and aftercare.
• Authenticity, documentation, and professional oversight are essential.
