Many people develop large bulging veins on the backs of their hands as they get older. Usually, this is due to skin relaxing and thinning with age, causing the veins to become more prominent and appear enlarged. There are several ways to treat this problem. One way is to treat the veins themselves with sclerotherapy injections. Another method is to use cosmetic dermal fillers such as Radiesse injected between the tendons to give the skin a fuller, more youthful appearance, and in so doing, the veins become less obvious. A combination of these two modalities can also be utilized in specific situations.
