I haven't had botox for over two years. Will it still work?

Thank you for your question. The Botox should work the same as it did 2 years ago. In some cases when there have been visible signs of aging Botox will work differently or administered differently in comparison to years before. Speak with your injector and discuss. Best, 

Botox works well even after some time off treatment.  I suggest you see an expert for treatment options.  Best, Dr. Emer.

Yes, botox will still provide excellent results after 2 years of not being injected. You may need to have an increased amount of injections in comparison to the amount previously received since it has been a long time between treatments. It is best to consult a board certified plastic surgeon however in order to properly assess what dosing of Botox will be required. Best of luck. James Lee

Patribrat - don't worry, it will work! remember the mechanism of action of botox.  The botox will work, the only difference being that the lines which you had on your forehead may be a little more prominent now than they were before as you have not had botox in over two years.  That being said, give it a try! as you know, for optimal results it really needs to be refreshed every 4-6 months (everyone is different and botox can last them a little longer).  Good luck!

Having gone two years without Botox, you are
most likely back to baseline and lines might be a little deeper due to aging.
However, Botox should still work. You will need to keep up injections every
three to four months to keep the results going. You should consult with a
Board Certified Dermatologist or Plastic Surgeon for recommendations.

Botox should work even after 2 years. However the finesse of the actual dosing and how it compares to previous doses that were used on you will be dependent on your expert cosmetic specialist. We are even more experienced with Botox molecules, and you should consider Dysport instead - you might like how fast it kicks in and how smoothe it is. In addition expert cosmetic dermatologists are using fillers like Juvedem, Emervel and Belotero for forehead lines as they might provide a more natural result! 

Botox should work fine after two years. What you injector might have meant is that it might take a series of injections to get the effacement of the lines you and before.

Dear patribrat:There is no reason that Botox should not work following a delay in its use. Remember that Botox works at the nerve-muscle level weakening all injected muscles including those of facial expression. Give the Botox a try and see how it works. Always use a Board Certified Plastic Surgeon or other well experienced Botox injector for your best results and consultation.All the best!

Of course it will work. there is no reason to say what you heard as it actually might give a better result compared to what you have now.  at any rate be sure you are seeing a board certified dermatologist or plastic surgeon

Thank you for your excellent question.  Botox will be equally effective after a two year lapse in treatment.  The only difference is that any forehead creases may have become slightly more prominent as a result of not receiving Botox for two years.  Ideally, Botox should be refreshed every 3-6 months to maintain optimal results.  Best wishes!
