No, senile muscle glue is not a technical term, nor is it a common name for botulinum toxin. Botulinum toxin is a neurotoxin produced by botulinum, which is widely used in medicine, beauty and other fields. In cosmetic applications, botulinum toxin is often injected into the skin surface to reduce wrinkles and improve facial lines, while senile muscle glue is a specific cosmetic product or treatment, so it is not.
