Frequently Asked Questions
Can resistance develop to XEOMIN?
Although complexing proteins are removed, no guarantee can be made that resistance will never occur. Antibodies to botulinum toxin can form. Reduced effect may also relate to dose, injection site or muscle condition. Reviewing previous products, timing and responses is advisable.
Does it work equally on all wrinkles?
It is used to soften wrinkles related to expression-muscle movement. Wrinkles caused by sagging or deep creasing may not improve sufficiently by reducing muscle movement alone, so other treatments may be considered according to the cause.
Will switching products resolve resistance?
The cause of reduced effect must be assessed first. Along with product choice, we review dose, injection sites, intervals, muscle condition and previous responses to plan further treatment.
Can I directly compare unit counts between products?
Botulinum toxin potency units are determined by the product and assay method. We do not directly convert units between products; the medical team plans treatment for the actual product and area.
What history should I disclose before treatment?
Tell us about previous products and dates, effects and uncomfortable reactions. We also check neuromuscular conditions, allergies, medications, pregnancy and breastfeeding before treatment.
Which symptoms require immediate help after treatment?
Seek emergency care immediately for difficulty breathing, swallowing or speaking, or severe generalized weakness. Also tell the clinic about unexpected changes in expression or strength, or discomfort.
