Thanks for your question, and I'm sorry to hear that you have had a negative experience with the Xeomin version of botulinum toxin A, which is essentially identical to Allergan's "Botox," which is also serotype A. I've been injected neuromodulators (Wrinkle Blockers) like Botox for 19 years, Xeomin for about 4 years, and Dysport for 3 years. I have injected them in 20 year-olds up to their 80's for medical reasons (uncontrolled spasms) and mostly for cosmetic reasons. Have never had any serious adverse reactions (e.g., breathing problems, severe weakness etc.). The wrinkle blockers are an excellent tool for patients wishing to fight aging changes and/or prevent some of them. There are some contraindications where they should not be used (myasthenia graves patients, ALS etc.), but "Botox" injections have been the number one cosmetic procedure for many years because when given properly they have such a high safety profile with great results all while avoiding surgery or as a complement to surgery and dermal fillers. Its not for everyone, but if you have wrinkle concerns I would seek out someone with excellent reviews and experience if you reconsider trying. Be sure to let your injector know of any medical conditions you have and any vitamins, supplements, or medications you take. Also look for a reputable injector, who reconstitutes it an ethical manner using FDA-approved and legally sourced botulinum toxin only. Best regards.
