BOTOX® injections are the most popular cosmetic procedure performed in the U.S., with almost 7 million injections administered each year. BOTOX® can be extremely effective in correcting dynamic wrinkles, those lines and creases that form over time as a result of repeated facial movements. But while the effects of these injections are well known, many people may be surprised to know the results don’t occur immediately.
Unlike most dermal fillers that are visible as soon as they’re injected into wrinkles and creases, it takes a little while for BOTOX® to work. As a neuromuscular agent, BOTOX® blocks the signals from specific facial muscles to the brain so the brain can’t “tell” muscles to contract. It’s this contracting action that tugs on skin, causing lines and wrinkles to form. The signal blocking isn’t immediate – in most patients, it takes at least a couple of days to start working and full benefits may not be visible for about two weeks. The time it takes for the injections to take effect can vary from one person to another, sometimes significantly. Age, the underlying musculature of the face and the depth and extent of wrinkling can all play a role in how long it takes before results are visible.
Once results are achieved, they can be maintained with regular “touch-up” injections. If you’ve never had BOTOX®, it can take a little time to determine how quickly your body responds. Be patient – most people find the results are worth waiting for.
