Hands can reveal your age and many people are now requesting equal time for their hands. Wrinkling, thinning of the skin and that "bony-look" which is actually due to loss of the collagen in the dermis, can all be treated with injection of cosmetic fillers. Radiesse is one of the best since it fills the hollow areas between the tendons and lasts several years.
For twisted, bulging hand veins, sclerotherapy is a safe option to shrink the veins. Usually one hand is treated at a time, since a compression glove must be worn for about a week after the treatment.
