Current materials and techniques in cosmetic hand injections.

Area of Science:

• Dermatology and Aesthetic Medicine
• Cosmetic Procedures
• Regenerative Medicine

Background:

• Aesthetic treatments are increasingly focusing on hand aging.
• This review examines current practices in cosmetic hand injections.

Purpose of the Study:

• To review materials, injection methods, and testing procedures for cosmetic hand injections.
• To identify effective substances and techniques for hand rejuvenation.

Main Methods:

• A comprehensive literature search of the PubMed database (1971-April 2024) was conducted.
• Studies on materials, injection techniques, and evaluation methods for aesthetic hand injections were included, excluding systematic reviews and case reports.

Main Results:

• Hydroxyapatite is a common material, but Poly-L-lactic acid (PLLA), platelet-rich plasma (PRP), and polycaprolactone demonstrated higher efficacy.
• Catheter-based injection techniques proved more accurate than needle-based methods.
• Ultrasound and the Merz hand partial scale are primary assessment tools.

Conclusions:

• There is a need for more extensive research, including randomized controlled trials comparing different fillers and long-term data for PLLA and PRP.
• Standardized outcome measures and long-term follow-up are crucial for advancing hand rejuvenation techniques.
• Increased public awareness relies on robust and valid studies on aesthetic hand injections.
