Let’s start by clarifying: Botox is a brand name for the injectable treatment that is used to smooth wrinkles and fine lines between the brows and on the forehead. Because it’s been around the longest and has been studied the most, people often use the term “Botox” as a catchall to describe this type of treatment even though there are several different brands that are currently FDA-approved for cosmetic use: Botox, Xeomin, Dysport and Jeuveau.
All four of these treatments fall under a class of drug called neuromodulators, which is defined by Merriam-Webster as: “something that potentiates or inhibits the transmission of a nerve impulse but is not the actual means of transmission itself.” Or, as we recently explained to our friend, Botox and other neuromodulators work by temporarily blocking the nerves of the facial muscles that create wrinkles.
How are Botox and Xeomin similar?
Both are made with a form of botulinum toxin type A, a protein substance that is used to reduce the appearance of fine lines and wrinkles caused by repetitive facial expressions (i.e., from squinting at your computer screen all day or frowning while you sit in daily traffic). When injected into the muscles underlying these areas, they block the signals from nerves to muscles, so they keep from contracting. The result? A smoother visage until the treatment wears off in a few months.
