Injection of skin fibroblasts cultivated in medium supplemented with human serum is a viable technique and provokes no side effects. Four injections given at 15-day intervals containing a total of 6.4 × 10(6) fibroblasts/mL resulted in significant improvement in periorbital skin flaccidity. Further studies should be conducted with larger sample sizes.
