Botox and Dermal Fillers combined with Radiofrequency will certainly rejuvenate the skin. However, I would either have the RF first and have the fillers and Botox the next day, or have the fillers and Botox and wait one week for the RF skin tightening procedure.
If you were to do Botox within a few minutes or hours of treatment, the mechanical massage of the RF device may massage the treated areas and move Botox into unwanted zones possibly giving you unwanted side effects such as a droopy eyelid or eyebrow. After 24 hour you are unlikely to move the Botox around at all. Another possibility is to have the RF treatment first and then have Botox on the same day.
you can resume your RF treatments in a day...while some people make an issue of waiting for a longer period of time, there's no reason not to proceed sooner
Many injectors combine botulinum toxin with other procedures, including fillers and radiofrequency treatments, during the same treatment session. If that is the case, the botulinum toxin should be performed last to prevent inadvertant spread of the Botox. To minimize this risk, the botulinum toxin can be given on a separate day. Since botox is inside the cell by 90 minutes, radiofrequency treatments could be started the next day in most cases.
I would suggest that you consult and discuss this with a board certified dermatologist as this will be an individual practitioners choice and will vary depending upon whether you received Botox or fillers.
Assuming you are treating the same area with both I would suggest waiting a day between your Botox and the RF treatments. You wouldn't want to accidentally spread the Botox. Hope that helps!
