I have very visible veins all over my body. Is there any way of making the veins on my chest less visible? (photo)

EJ thank you for sharing your photos. I agree with you that your skin is very fair / translucent. I also agree with the other doctors that visible veins are normal looking reticular veins. They do not have to be treated but can be treated. The treatment I would recommend would be foam sclerotherapy and it would likely take 2- 3 treatments. There are some risk with foam sclerotherapy and I would only consult with a vein specialist surgeon who has a lot of experience treating chest veins.

I agree that foam sclerotherapy is very successful and efficacious for chest/breast veins and several treatments may be necessary to achieve an optimal outcome. 

The pictures that you show are very good and this is a common problem that I treat.  Sclerotherapy for these types (reticular) veins is the treatment of choice and is very safe. It usually requires several cycles of treatment but works well.  You should see someone with experience treating veins in this area with sclerotherapy.
