This is extremely hard to treat. In order to give lasers the best possible chance, brows NEED to be shaved, as the laser energy is taken up by hair. I have treated several cases in the past, some respond, some don't, however if one were to try the settings of the V BEAM or Excel V has to be very high- preferably bruising settings. The other option is to do a test spot, ie. 10 mm spot size on your lateral brow, area shaved. Best advice I can give you.CheersDr Davin LimLaser and aesthetic dermatologistBrisbane, Australia.
