Facial slimming – should I wait until my face is back to its original state before I book an appointment?

You do not have to wait until the muscle contraction completely goes back to its original state to have it treated again. As long as there is a small amount of muscle contraction, it can be treated.
Regular treatments can help give longevity to your results and regular treatments may mean you mightn’t need the same dose as the original, if the muscle has already been significantly weakened.
