About 2 Weeks Ago I Had Spider Veins Removed from my Legs Using a Cutera Coolglide by a Nurse. I Now Have Brown Scabs?

The forehead dent can easily be treated with fillers. That is not a big problem.The vein can also easily be treated with multiple modalities which are not limited to microphlebectomy (if it is large), RF technology, ohmic thermolysis, sclerotherapy or a long pulsed laser using Nd YAG technology...

Yes, V-Beam (i.e pulsed dye laser) or intense pulsed light (IPL) can often completely or nearly completely remove facial telangiectasias.   However, most cosmetic physicians will not promise this.

These forehead veins are fairly common and can be treated by 4 or 5 different modalities based on their size.SInce yours are 'prominent', the options are microphlebectomy or sclerotherapy.Treating these forehead veins is not likley to get rid of your migraine headaches. 

Thank you for posting the picture. The treating physician may be able to reduce this effect after careful examination in person.Options may be to treat it like an acne scar with sublative technology that uses RF energy like eMatrix or fractional laser treatment locally. 

The technologies for thermocoagulation that are available on the market are well described below. Sclerotherapy with foam is the preferred technique for spider veins, reticular veins and some varicose veins. Watch the clip below from The Doctors TV Show. 

While your concerns are legitimate, the risks are very small. I recommend that given such concerns that you have, that you consult an oculoplastic surgeon who treats problems such as these with lasers.
