Is it true that Botox can train your muscles?

Thank you for your question.  The duration of action for Botox will increase over a period of years after repeated treatment. This is because the muscles may decrease in caliber after extended periods of inactivity.

This is true. Repeated use of Botox can cause a gradual relaxing of the treated muscles, making your results last longer. 

Thank you for your questions.  Yes, over time Botox's effects may result in muscle atrophy which may lessen the amount of Botox needed in subsequent treatment periods, or in longer overall effects.  If you were to stop with your Botox treatments, the previously injected muscles will hypertrophy, increasing back to their original size.  Hope this helps. 

Dear Adrian, For the majority of patients, the more frequently you receive Botox the less units you will need over time since the muscle will atrophy.  It does not prolong the effects of Botox. Botox will last approximately 3 months. Consult with a Board Certified Plastic Surgeon for more information.

Dear adrian23456:Botox, Dysport and Xeomin are the FDA approved medications for injections for muscle relaxation. These medications do not alter your mind in any way to train or modify behavior. They do block the acetylcholine release from the end of a "motor" neuron at the neuro-musclular junction where it fails to trigger a muscle cell contraction.Over time, these medications if injected consistently can atrophy the muscle disabling them from future use. Other nearby muscles may act to overcome the loss in expression strength; called recruitment. These muscle may then also need a Botox injection to relax them.The "training" comes with your perception in reducing or altering that expression and making a mental alteration in future expressions of those kind.This would be similar to pressing against the muscle each time you contract the scowl or glabella muscles between the eyebrows and purposely relax then not to scowl. Over time, you will unconsciously not scowl when you wish to express yourself in that way. These drugs do not affect or trigger such a habit. It is the lack of activity that does create the habit. You are correct in that the injected muscles can be "permanently" relaxed (by micro-paralysis) but the medication does not create a expression habit.Interesting question. I hope this has been helpful. All the best.
