Botox, or any anti-wrinkle injection will have only a short-term effect. Exactly how long it will last varies from person to person, and depends on how your body metabolises the toxin but the norm is anything from three to six months.
In order for muscles to contract, nerves release a chemical messenger at the junction where the nerve endings meet muscle cells. Botox and other anti-wrinkle injections block the signals from the nerves to the muscles by disabling the nerve receptors. The injected muscle can no longer contract, which causes the wrinkles caused by the movement of that muscle to relax and soften.
However, over a period of three to six months, new receptor cells will develop and movement will return to the muscles.
As muscle action gradually returns, the lines and wrinkles on the skin over the muscle begin to reappear and need to be treated again. However there are various things that can influence how long your Botox will last.
What affects how long Botox lasts?
- Your personal metabolism - your body will process Botox in its own timeframe. Athletes and people who work out a lot will have faster metabolisms and Botox will not last as long.
- The areas being treated - Botox in the forehead and between the brows typically lasts longer.
- Your facial expressions - some people ‘forget’ how to use their facial muscles or stop making frowning expressions even after the Botox begins to were off. They’ll have longer lasting results than those who are more animated with their facial expressions
- The skill of your practitioner - the best injectors know how to accurately place Botox for maximum benefit. They also know exactly how much to use and how to space it. As we always say with all aesthetic tweakments - do your research and choose your practitioner carefully!
- How often you have Botox - some doctors report that those who have Botox frequently can go longer between sessions.
When do you need more Botox?
How do you know when you need a Botox refresher? You’ll first start to notice the return of the muscle movement in the area and then you’ll start to see the return or deepening of the wrinkle, then you know it’s time to book another appointment.
