Neurotoxin injections work by blocking the nerves from activating the facial muscles. When injected, the target muscles are unable to contract normally, which stops the skin from being pulled and results in fine lines and wrinkles becoming smooth.
Botox® (OnabotulinumtoxinA) is generally the first neurotoxin that comes to mind when discussing treatments for wrinkles and lines caused by facial expressions like frowning, squinting, smiling, and other expressions. Botox® works to block communication between nerves and the facial muscles, which leads to a smoother appearance of wrinkles.
Dysport (abobotulinumtoxinA) is an injectable neurotoxin. Like other neurotoxin treatments, it is mainly used to smooth dynamic wrinkles or those wrinkles which form as a result of facial movements like frowning, squinting, smiling, and other expressions we tend to make day after day. Treatment works by blocking nerve impulses to the muscles, causing them to relax. As a result, your expressions soften and the dynamic wrinkles are greatly reduced.
Minus a few proteins, with Botox® or Dysport®, the active part of the toxin is encapsulated in complexing and accessory proteins, and this was by design. Xeomin® (incobotulinumtoxinA) differentiates itself from other neurotoxins by undergoing an extra step of purification so that there is no complex protein. The middle, active portion is the same in all of them. It behaves the same way as Botox® and Dysport®. The only key differences are on the side of the physician administering the treatment. Xeomin® does not require refrigeration, and the vial must be flipped instead of swirled to ensure the ingredients are dissolved.
