lyn7,Without implying anything regarding the safety or efficacy of microcurrent facial treatment, which uses a small electrical stimulator to move the facial muscles, it will still stimulate those muscles if the effect is by direct electrical muscle stimulation. However, if the electrical stimulus must first be picked up by the nerves and then transmitted to the muscles there will be no motion because of the way Botox temporarily uncouples the nerves from the muscles they serve. In cosmetic treatments Botox is injected targeting the muscles, but it is actually the motor nerves to those muscles that is affected by the paralytic agent, and not the muscles themselves. Since Botox does not move around appreciably after it is injected, and the binding of the Botox to the nerve endings occurs quickly, there should be no reason that the effect would be changed by later muscle stimulation. It may be prudent to wait a couple of days, however, because swelling may change the way the electrical impulses are transmitted through the soft tissues. Likewise, muscle motion is not going to move fillers that have been properly injected, so these electrical treatments should not impact the outcome of fillers. I hope that this helps.
