Is it okay to do a tattoo after a vein treatment?

It is best to wait until you heal from your venous ablation.  After the procedure there is often some tenderness, slight swelling and bruising.  Tattooing over the area would not only be more painful but potentially risk infection also.  Just wait several weeks until you are fully healed and then get the tattoo.

As long as you don't have any bruising or trapped blood (this would feel firm under your fingers), then it should be fine. 

Vein treatment may include endovenouos therapy that heats the vein EVLT or radiofrequency, Sclerotherapy, and Phlebectomy and the goal of the vein treatments are closure of the vein and the redirection of blood flow. After a vein treatment you might experience swelling, bruising, and hyper-pigmentation until the fibrous tissue from the vein that was treated gradually incorporates into the surrounding layers of the skin. Some patients heal faster than others, consult with the specialist to make sure you are ready and completely healed before any other procedure on the skin including a tattoo.

It's important to have the treated vein heal before placing a tattoo needle over it. Your risk of infection and scaring and poor results is increased with the trauma of a tattoo placement. 

I would wait until the vein procedure is healed before getting a tattoo.  It may take a few weeks for your bruising   from the vein procedures to go away.  You don't want to have a tattoo on top of the vein procedure and risk infection in the area that you just had the veins treated in.  I would wait until the vein procedure is healed

Yes, it is OK to have a tattoo after a vein treatment but I would have my patients wait until all bruising and tenderness is gone, any swelling or firmness in the skin has completely resolved, there are no further treatments planned in the area, and that there are no associated unresolved issues (such as hyperpigmentation) or problems following the treated area. This process may typically take several weeks, if not 2 or 3 months. Safety, Safety, Safety!

If the tattoo is in the area of the vein treatment - wait.  Tattooing is not an emergency.  If the tattoo is not near the vein treatment - then you can have it done the next day.

You can do tattoo after vein treatment but leave for at least 6 month to ensure that all the bruising have settled down. If the tattoo in an area away from the vein treatment then you can do this after 4 weeks

If you are getting ablation treatment for your varicose veins, you most probably going to have some bruising and some discomfort in procedure areas. So it is preferable you wait 3-4 weeks with your tattoo for your comfort and optimal results. If you are getting cosmetic sclerotherapy, I,  definitely, would not recommend you mix these procedures together.Add tattoos only after all spider veins are gone, which might take 2-3 months or more after sclerotherapy course.

Thank you for your question.EVLT for the great saphenous vein is done aling the inner thigh where few, if any people get tattoos - or in the inner leg below the knee ot behind the leg (posterior leg) where tattoos are common. I recommend that you wait a week after EVLT to pursue your tattoos.
