Anti-Wrinkle injections are the UK’s number one method for treating facial wrinkles and lines. Wrinkles are caused by repeated facial muscle contraction during expressions. Over time these lines become deeper and more prominent. Botulinum toxin injected into these muscles causes them to relax and in turn causes facial lines and wrinkles to soften or disappear depending on their depth. Additionally in trained practitioners hands, these injections can also be used to relax muscles and by the action of opposing muscles create lifting effects. Treatment duration varies, but typically 1 treatment lasts 3-4months.
