Botulinum toxin, commonly referred to as Botox, is a neuromodulator that helps relax the muscles, prevent formation of wrinkles, and helps with skin rejuvenation. There are 4 available products that are FDA approved for use in the US: Jeuveau, Xeomin, Dysport, and Botox. The treatment takes about 15-30 minutes and results last between 3-5 months. There is little to no downtime. You will have some small bumps to the injection site, but they can be expected to resolve later in the day. Bruising is also possible, but not common. Makeup can be applied 24 hours after the treatment.
