Background: With the widespread popularity and development of aesthetic treatments, the focus has extended from facial aging to include the aging of hands. The primary aim of this study is to review the current materials, methods of injection, and testing procedures employed in cosmetic hand injections.
Methods: PubMed database (from 1971 to April 2024) was searched to identify relevant studies on materials, injection techniques, and evaluation methods associated with aesthetic hand injections, excluding systematic reviews and medical record reports.
Results: A total of 1815 articles were identified, of which 41 articles were included. This study summarizes the current materials, injection techniques, and outcome evaluation methods used for cosmetic hand injections, while discussing observations and making recommendations.
Conclusion: Hand skin conditions tend to receive less attention than cosmetic facial injections. In existing studies of injected substances, hydroxyapatite remains the main material used for cosmetic hand injections. Poly-L-lactic acid (PLLA), platelet-rich plasma (PRP), and polycaprolactone injections were significantly more effective than other substances in the hand. In commonly used injection techniques, catheter-based injection methods are more accurate than needle positioning and dose. The most commonly used assessment methods remain ultrasound and the Merz hand partial scale. At present, there is still a relative lack of research on aesthetic hand injections, and extensive and in-depth research, such as randomized studies comparing hyaluronic acid and calcium hydroxylapatite and longitudinal data on the results of PLLA or PRP, is recommended to further develop hand injection techniques with lasting aesthetic results. Increased public awareness of hand injections derives from more reliable and valid studies. And we need standardized outcome measures and long-term follow-up data in future studies.
