The first time you have anti-wrinkle injections, you can expect the results to last for between three and six months. Results vary depending on how well you look after your skin, as well as your skin type and the severity of the wrinkles you’ve had treated. Using anti-wrinkle injections regularly can increase the amount of time that the effects last for. Because it freezes the muscles, over time these muscles will become shorter and smaller. This can often mean that, if you have your treatment repeated regularly, you start to need fewer treatments with greater time spans between them. When you’re thinking about how long anti-wrinkle injections last, it’s important to consider how many times you’ve been treated, as well as other influencing factors. Younger people with less depth to their wrinkles will usually have longer lasting results than those with deeper wrinkles and less elastic skin.
