Can Halo Laser be used after facial fillers?

A very simple answer is in order.  Halo can be done over the top of all fillers, with the possible exception of Belotero which is the most superficially injected filler.   Think of it this way: Halo treatment uses two different wavelengths of laser energy, right on top of each other.  Only laser that can do this.   Treatment is based on depth of treatment as well as density(the number of holes you are place per area).  A deep treatment with Halo is creating columns of injury at 500 microns, which is about 0.5 millimeters.  Virtually all fillers are easily 2+ mm in depth or more.  Halo effectively is treating way above where the fillers are. 

Yes, you may.  Consult with your provider on the type of filler you have had injected.  Usually, these treatments are in different depths of the face and are not an issue. 

Having fillers in place is not a contraindication to having a Halo Laser. If interested in getting fillers after the procedure I would wait until you feel there is no residual swelling and your skin is clear. This may be any time from a couple of days to a couple of weeks based on the aggressiveness of your treatment.The combination of volume replacement with fillers and skin rejuvenation with laser treatments is a very nice complimentary way to stay looking fresh and rejuvenated. If you are interested in trying to do both procedures at the same time I would speak with your physician about their specific recommendations based on what you need and where.
