Botox cosmetic injections were created to primarily help reduce the appearance of facial wrinkles. Botox cosmetic injections use a chemical called onabotulinumtoxinA which helps to temporarily prevent muscles from moving. Some of the most common reasons patients get Botox is to help reduce the appearance of fine lines and wrinkles in the face. Botox can help to relax the muscles and offers a softer and smoother appearance of your skin. Botox injections can take effect almost immediately and will last upwards of 3 to 6 months. As muscle actions begin to slowly return, the lines and wrinkles will again start to appear, much often less severe with time than the first injection, because the muscles are shrinking. You should be getting maintenance injections to keep your desired results every 3-6 months. Talk to your provider about maintenance injections before you leave your appointment.
