Botox / Neuromodulators

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.

Botox Cosmetic

The FDA approved Botox for medical use in the 1980s and it received its first FDA approval for aesthetic use in 2002. Botox is an effective treatment for the temporary reduction of forehead wrinkles, frown lines (glabellar lines), and wrinkles around the eyes.  Botox injections are quick, usually taking less than 30 minutes, and are relatively painless. Botox treatments require little, if any, recuperation time and with the exception of possible minor bruising (in come cases), post-treatment recovery is negligible, causing no major disruptions to your normal routine.

Botox Therapeutic

In addition to its cosmetic application, Botox is used as a medical therapy for the treatment of migraines, TMJ disorder (temporomandibular jaw disorder), and excessive sweating (hyperhidrosis). Sufferers of all three conditions can experience long term relief and improved quality of life. More about Botox therapeutic.


Similar to Botox, Dysport injections soften moderate to severe frown lines (glabellar lines), “bunny scrunch lines” and crow’s feet. Dysport results generally appear more quickly than Botox and disperse more widely, which has both advantages and disadvantages depending on the type and location of the wrinkles being treated. Like Botox, Dysport is a comfortable treatment requiring little downtime or recovery time. More about Dypsort.


Xeomin is another neuromodulator (botulinum toxin type A) made from the bacterium Clostridium botulinum; however, Xeomin contains no additives so may reduce the risk of allergies or the development of resistance to the drug. Xeomin is an effective treatment for frown lines, crow’s feet, forehead lines, lip lines and “bunny scrunch” lines between the brows. Xeomin treatments are quick (usually less than 30 minutes) and require little, if any, post-treatment downtime. More about Xeomin.
