The three most exposed areas of the body that give away a person’s age are the face, neck, and hands. Rejuvenation of the hands is an often simple and nice addition to facial and neck aesthetic rejuvenation.
When examining aging hands, the three most prominent features are decreased volume in the interosseous spaces (leading to increased crepiness of the skin and increased show of extensor tendons), lentigines, and prominent veins. Therefore, the treatment for hands is quite simple: Restore volume, treat the pigmented lesions, and if needed, treat the prominent veins.
The anatomy of the dorsal hand can be divided into three major compartments. First, the skin, which on the dorsal hand is quite pliable. Second, the subcutaneous tissue, which consists of a loose areolar tissue where the lymphatics and veins lie. Third, beneath the subcutaneous tissue is the dorsal fascia of the hand, which is contiguous with extensor tendons and underlying compartments. It is in the subcutaneous layer (or loose areolar tissue) where fillers or fat are placed to treat volume loss.
While several fillers are currently used off label for hand rejuvenation, the Food and Drug Administration is meeting in February to consider officially approving Radiesse for this indication. Currently, hyaluronic acid (HA) fillers, calcium- hydroxylapatite (Radiesse), poly-L-lactic acid, and autologous fat are all utilized. I tend to use HAs in this location because of the reversibility, if needed, and decreased risk of nodule formation. Several techniques exist, including injecting between each tendon space vs. a bolus technique. I tend to use a bolus technique, where one or two boluses are injected while tenting the skin up to ensure injection into the correct plane and to avoid the vessels. Subsequently, the boluses are massaged into place while the patient makes a fist.
Once the interosseous spaces have been treated, the veins often appear less prominent and often don’t require direct treatment. I typically do not treat the dorsal hand veins, but sclerotherapy can be performed. Lentigines may be treated with a variety of devices including intense pulse light, Q-switched lasers, and fractionated nonablative lasers. Chemical peels and topical antipigment agents also may help to a lesser degree or also may be used for maintenance to keep the lentigines away.
