Treatment of the aged hand with injectable poly-l-lactic acid.

We report the use of injectable poly-l-lactic acid (PLLA) for volume restoration in a 45-year-old white female who was concerned about the appearance of her hands. The patient expressed a desire for long-term restoration, and selected injectable PLLA because of its known 2-year duration of effect, although she was informed that injectable PLLA is not FDA-approved for use in the hands. After reconstitution with 8 ml of diluent plus lidocaine, 0.1-0.2-ml aliquots of injectable PLLA were injected into selected sites, up to 5 ml per hand. The patient underwent three identical treatments, followed by postinjection use of moisturizing cream and massage; improvement in appearance was noted by the patient between the second and third treatments. Correction was maintained for at least 18 months, with no adverse events. We have also briefly reviewed the literature on the use of injectable PLLA for volume restoration in the hand.
