If you stop getting injections after several years of Botox use, your wrinkles may come back worse than they were before treatment. If you then restart the treatments, your doctor will adjust your dose accordingly to maintain the results.
New wrinkles form as we age because our skin loses elasticity and fat pads over time. As these parts of the skin shrink, the skin around them forms creases or crinkles that can become permanent even after treatment has stopped.
