The BTA Procedure:
For any BTA procedure, your doctor might have you apply ice to the area a few minutes before treatment. This is for two reasons: it causes the vessels in the skin to constrict which helps reduce bruising, and it helps decrease the small amount of pain associated with multiple injections. Ice can be beneficial for the same reasons after the BTA treatment.
Once seated upright, the doctor will have you contract the muscle in the area being treated so that he or she can better target the injection into the muscle. Thus, if you’re receiving injections for wrinkles between the eyes, you will be asked to frown.
On average, you’ll receive three injections per muscle (depending on the area being treated, more or less injections may be needed). With each injection you will feel a needle prick, then a mild stinging or burning for a few seconds as the toxin flows in to the muscle. Again, depending on the area being treated, you may be asked to gently press a gauze pad against the injection site and/or hold to it for a few minutes.
The whole process takes about ten minutes to half an hour, depending on the number of areas being treated. As soon as the series of injections is completed, you can go back to your regular activities. As stated above, the doctor will probably ask you to refrain from bending or laying down for approximately four hours after the injections until the toxin has had time to attach to the nerve-muscle connection. You will be asked not to rub the area in order to prevent the toxin from spreading to adjacent muscles.
