Botox ®, Dysport ®, and Xeomin ® are types of injectable prescription medications known as neuromodulators, but what is a neuromodulator? Neuromodulation describes two things: part of a biological process and action or intervention that affects that process. As a physiological process, neuromodulation is the regulation of neurons by neurotransmitters. As a therapeutic treatment, neuromodulation describes the electrical or chemical alteration of nerve activity. In skin aesthetics, neuromodulator injections are used to block nerve signals that control muscle contractions. Muscle contractions are partially responsible for the appearance of dynamic wrinkles – wrinkles that appear temporarily when we laugh, smile, purse our lips, wince or frown. When a targeted muscle is temporarily blocked by a neuromodulator, the appearance of wrinkles is reduced.
Safety of neuromodulators
Neuromodulators injection treatments are safe, according to a recent study, when injected properly by an experienced aesthetic treatments doctor. The study – published in JAMA (the Journal of American Medical Association) – researched incidents of adverse effects from injectable neuromodulators, fillers and laser treatments. The conclusion: less than 1% of patients experienced adverse effects and these were mostly minor and transient.
