Corrugator muscles sore & seem more prominent/tensed after recent Botox. Is retreatment necessary? How long until it improves?

Thank you for your question in regards to Botox.Botox can take up to two weeks before total correction has occurred. I suggest waiting until then, at that time if you still have concerns with your injections, schedule a follow up appointment and additional units may be added. To be sure, see two or more board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment.I hope this helps.

Botox takes 2 weeks to see the results and often you can have soreness or headaches after botox injections. I suggest giving it two weeks and seeing what the results are then.  Best, Dr. Emer.

It can take 1-2 weeks prior to seeing relaxation of muscles after Botox treatment.  Please be patient.  It is odd that your muscles feel tense and more noticeable; perhaps you have a small hematoma from the needle poke.  If the bruise is deep, you may not see discoloration. You might ask the RN if she noticed more blood than usual when she withdrew the needle.
