Xeomin (incobotulinumtoxinA)

What it's good for: Xeomin is said to be a powerful treatment for glabellar lines, known as the vertical wrinkles or "11's" between the eyebrows. Xeomin injections effectively reduce the appearance of "dynamic" wrinkles—those that become evident when you frown, squint and laugh.

Who it works for: If you're worried about your frown lines, then stop! Scowling can actually exacerbate these wrinkles. If you're looking for a way to temporarily eliminate these lines, then Xeomin might just be it. The injectible wrinkle reducer can keep these creases at bay for up to four months.

Recommended age range: Xeomin is recommended in patients over the age of 18 and under 65.

When will I see results?: Initial studies have found that it takes approximately seven days to notice improvement after treatment with Xeomin. As with any injection, your muscles may become swollen or bruised afterward depending on your individual reaction.

How long it lasts: Xeomin injections last an average of 12 weeks, according to clinical studies, though the product is still in trial stages in the US. Patients should wait at least 12 weeks before re-injecting an area with Xeomin.

Key benefits of Xeomin: Because of its chemical construction, Xeomin is said to be more “pure” than Botox and Dysport, meaning that allergic reaction is less likely.

Licensed uses: Xeomin was approved by the FDA in July 2011 for the treatment of glabellar lines. It has already gained clearance in 14 countries (and counting) around the world, including the United Kingdom, France and Spain.
