Fractional ablative photothermolysis using erbium:YAG laser (2,940 nm) is a promising option for skin resurfacing with reduced risk and downtime compared to existing laser methods.
SD induces an inflammatory reaction in subcutaneous human fat and dose-dependent adipocyte lysis with acute pain and fibrosis. No systemic effects were detected. Further studies will establish the best dose-result ratio, frequency of application, and long-term safety.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
