Also, after 6\u00a0months better GAIS scores were observed in group I compared to group II and in group II compared to group III. Assessment of different esthetic parameters measured by the Antera 3D camera revealed a statistically significant improvement in all parameters (periorbital and mid-face) in group I and in most of parameters (periorbital and mid-face) in groups II and III with more evident improvement after 1 month compared to after 6\u00a0months.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Intradermal microbotulinum toxin A is a cost-effective method for improving periorbital and mid-face wrinkles with a better effect of 1:5 than 1:7 and 1:10 dilutions.<jats:list list-type=\"bullet\">\n                  <jats:list-item>\n                    <jats:p>Facial wrinkles possess a great burden on patients' psychological status, and the emergence of novel rejuvenation technique with minimal side effects is necessary.<\/jats:p>\n                  <\/jats:list-item>\n                  <jats:list-item>\n                    <jats:p>MicroBoNT-A usage in the literature was through variety of dilutions and concentrations.
