Employing hyaluronic acid-based mesotherapy for facial rejuvenation.

BACKGROUND: Mesotherapy is a method of treatment in which biocompatible substances are injected in small aliquots into different levels of skin. This technique can be used for facial rejuvenation. AIM: To comprehensively evaluate efficacy of different hyaluronic acid (HA) materials for skin rejuvenation, and discuss longevity of these products, potential adverse effects, and different injection techniques. MATERIAL AND METHODS: We searched Pubmed, Scopus, Web of science, Google Scholar, Embase, Cochrane Library, and Science direct until April of 2022. Thirty-four articles were selected including 23 articles about non-cross-linked HA and 11 articles about cross-linked HA. RESULTS: Eleven and five different non-cross-linked HA and cross-linked HA materials were utilized, respectively. Treatment sessions for non-cross-linked HA were between 1 and 6 at weekly-to-bimonthly interval, and for cross-linked HA were 1-3 at 4-36 weeks apart. In most of the studies, serial micropuncture technique with 23-32 gauge needles was used for injection. Other injection techniques were Nappage (picotage), depot and micro-linear. CONCLUSION: Mesotherapy with HA-based fillers is a favorable method for restoring youthful appearance, rejuvenation, and revitalization of skin. Proper selection and precise placement of HA in desired level of dermis is an essential key to optimize improvement and minimize side effects including skin irregularities and Tyndall effect. Adjuvant therapy with additional rejuvenation procedures to enhance esthetic results is required especially in elderly individuals with severe photodamaged skin. Moreover, preservation of esthetic results requires maintenance therapy every few months.
