Sclerotherapy For Ordinary Bulging Veins On Arms and Hands? (photo)

I would discourage you from treating your arm and hand veins with sclerotherapy as these are functional veins.  

Your picture shows large forearm veins.  These can be treated as a strictly cosmetic procedure and I have treated forearm veins several times in the past.  I recently had a 40 year old women model with similar veins. She had an excellent result from treatment.  I treat these veins with endovenous laser just as is done on leg veins.  This is a simple procedure done under local tumescent anesthesia.  I do not use sclerotherapy for these veins and they need to be large enough to accommodate the laser filament.  There is no downtime and normal activities resume the following day. I do not think that treating these veins will affect the color of your skin and I want to stress that this is simply a cosmetic treatment.  I realize that there is controversy among physicians in treating these veins, but not every single vein is treated and there are always other arm veins which can be used in the future if necessary.

I would strongly discourage you from trying to treat the veins on your arms and hands as these are functional veins that are required to move blood to and from the heart. These are not the same as spider veins or varicose veins which are non-functioning and a cosmetic nuisance, typically on the legs.
