I'm interested in shrinking the large veins on top of my hands. Am I a candidate for Sclerotherapy? (photos)

Thank you for the question! Currently sclerotherapy is the treatment of choice when treating enlarged and bulging veins. It uses a sclerosing solution that causes the vein to shrink. Usually it takes only 1 to 2 sessions to achieve fading of the undesirable veins.  
Another minimally-invasive treatment option is Radiesse, an injectable filler that will reduce the appearance of prominent veins on your hand. 
An in-person exam with a board-certified plastic surgeon is the best way to assess your needs and obtain expert medical advice. Best of luck! 

There are many options of treatment including fillers to hide the veins, sclerotherapy and sometimes microphlebectomy. Check the information on the link below for videos as well. 

May want to consider a combination of limited incision phlebectomy and fat injections for rejuvenation of the hands.  

There are several options for treating hand veins including sclerotherapy, removal through mini incisions (microphlebectomy) or laser ablation (endovenous).  My treatment of choice is a combination of laser ablation and sclerotherapy.  Usually one laser session is necessary but several sclerotherapy sessions may be needed.  I have been doing this procedure for over 12 years with excellent cosmetic results.  Once the veins are removed then decisions can be made on fillers. The cost varies  depending on the extent of the veins in each hand.  I am sure that there are doctors in your locale who can solve your problem.
