XEOMIN

Xeomin® is a purified injectable neuromodulator containing Incobotulinumtoxin A, a highly purified form of Botulinum Neurotoxin Type A used in aesthetic medicine and therapeutic treatments. It works by temporarily reducing muscle activity, helping to smooth dynamic facial wrinkles caused by repeated facial expressions while maintaining a natural-looking appearance.

Unlike some other botulinum toxin products, Xeomin® undergoes a specialized purification process that removes complexing proteins, leaving only the active neurotoxin. This makes it a “naked” botulinum toxin formulation, designed to provide precise muscle relaxation with a lower protein load.

Product Origin

• Brand Name: Xeomin®

• Active Ingredient: IncobotulinumtoxinA

• Manufacturer: Merz Pharma

• Country of Origin: Germany

• Product Type: Botulinum Toxin Type A injectable

• Available Strengths: Commonly supplied in 50 Units, 100 Units, and 200 Units vials (depending on market availability)

Composition

Each vial contains:

• IncobotulinumtoxinA (Botulinum Neurotoxin Type A) – active ingredient

• Human serum albumin – stabilizing agent

• Sucrose – stabilizing agent

Xeomin® does not contain accessory complexing proteins (such as hemagglutinins), which differentiates it from many traditional botulinum toxin formulations.

Mechanism of Action

Xeomin® works by temporarily blocking the release of acetylcholine, a chemical messenger responsible for triggering muscle contraction. By reducing communication between nerves and targeted muscles, it decreases excessive muscle activity, allowing treated areas to relax and resulting in smoother skin appearance.

Aesthetic Indications

Xeomin® is commonly used in cosmetic treatments for:

• Glabellar lines (vertical frown lines between the eyebrows)

• Forehead wrinkles

• Crow’s feet (lines around the outer corners of the eyes)

• Bunny lines (nasal wrinkles)

• Perioral lines (fine lines around the mouth)

• Chin dimpling caused by overactive chin muscles

• Masseter muscle reduction for facial contouring (off-label in many regions)

• Neck rejuvenation and platysma band treatment (off-label depending on location)

Therapeutic Applications

Beyond aesthetics, Xeomin® is also approved in various markets for medical conditions associated with excessive muscle activity, including:

• Cervical dystonia

• Blepharospasm (abnormal eyelid muscle contractions)

• Upper limb spasticity

• Sialorrhea (excessive salivation)

• Other neurological movement disorders (depending on regulatory approval)

Key Benefits

• Highly purified formulation with no complexing proteins

• Natural-looking facial results by relaxing targeted muscles without affecting facial expression excessively

• Precise and predictable muscle relaxation

• Consistent clinical performance

• No refrigeration requirement before reconstitution in some markets, offering convenient storage advantages compared with certain alternatives

• Suitable for repeated treatments under professional supervision

Duration of Results

Results typically begin to appear within 2–7 days after injection, with peak effects developing over approximately 10–14 days. The effects generally last around 3–4 months, although duration may vary depending on the treatment area, dosage, individual metabolism, and muscle activity.

Administration

Xeomin® is supplied as a freeze-dried powder for injection and must be reconstituted with an appropriate diluent before use. It should only be administered by qualified healthcare professionals trained in botulinum toxin injection techniques.

Storage

• Store unopened vials according to manufacturer instructions.

• Protect from excessive heat and contamination.

• Reconstituted product should be used within the recommended timeframe specified by the manufacturer.
