Will using Botox for glabellar lines lead to smoother skin and less product usage over time?

Botox use doesn't retrain muscles as your facial expressions are "hardwired" from the brain to the nerves to the muscles. What Botox does is prevents the muscles from being stimulated by the nerves and thus, they relax the muscle for 3-4mo but when it wears off the muscles have their full capacity again. With repeated injections of botox you will have continued improvement of your wrinkles but with age usually we see people need a higher dose as the years go on since there are more wrinkles as the skin ages. I hope this helps!

By consistently using Botox over several years some patients may be able to go longer between treatments due to atrophy of the treated muscles. However, most patients need to repeat Botox treatments approximately every 3 to 4 months in order to maintain the results.
