Neurotoxin or neuromodulators are proteins derived from botulinum toxin that is injected underneath skin in order to minimize or smooth out lines and wrinkles on the face. When low doses of neuromodulators are used, it selectively weakens or relaxes facial muscles, giving the recipient a clean, smooth facial appearance. There are various brand names for botulinum toxin A such as dysport, botox and xeomin.

What are the possible side effects of neurotoxins?
Like any cosmetic injection treatment, there can be some localized effects at the injection site. These effects can include redness, swelling, bleeding or bruising. These effects are usually mild, short-lived and self-limiting, usually disappearing after a few days.
Some patients have reported having flu-like symptoms after their Botox injections, including headaches, fatigue and muscle pain. There are also some reports of dry mouth, dry eyes and droopy eyelids. Although these adverse effects are rare.
