Formulation and Purity
Botox includes both botulinum toxin and accessory proteins. These added proteins help stabilize the molecule but do not contribute to its wrinkle-relaxing effects.
Xeomin is stripped of these proteins. It is known as a "naked injectable," containing only the purified neurotoxin.
Why this matters: some patients who receive regular Botox injections may eventually develop antibodies to the accessory proteins, which can reduce effectiveness. Xeomin's pure formulation may reduce that risk, which can make it a useful alternative, especially in long-term treatment plans.
