Xeomin is a dermal filler used to treat moderate to severe frown lines between the eyebrows in adults. The main product in Xeominis medically known as incobotulinumtoxinA (the same neurotoxin used in Botox) which is made from the bacteria that causes botulism, a particularly nasty form of food poisoning. Botulinum blocks the nerve activity in your muscles which causes a temporary reduction in the muscle activity and thereby relaxes them. Xeomin is very similar to other fillers on the market, including Botox and Dysport, which are all FDA approved injections for the treatment of facial wrinkles.
