What is it about?
102 Patients were treated with a mixture of S‐HA (Restylane Vital®) and abobotulinumtoxinA (Dysport®).

Why is it important?
Using an automatic injector, microdroplets of the mixture (0.001cc of S‐HA and 0.125 U abobotulinumtoxinA) were delivered into 1000 intradermal sites on whole face except eyelids.

Topographic Computer Analysis for Acne Scar Treatment on Face accompanying Biopsy Study after Dermal Injection of Hydrotoxin Mixture
Acne during youth can leave permanent facial scarring. The depressed acne scars can be treated by injection of stabilized hyaluronic acid (S‐HA) into the dermis. Due to the large number of acne scars, manual injection methods are technically difficult, and bear high risk of lump formation in the dermis. Therefore, the author designed a specific injection method to solve the two abovementioned problems.
Topographic Computer Analysis for Acne Scar Treatment on Face accompanying Biopsy Study after Dermal Injection of Hydrotoxin Mixture
The topographic computer analysis using point‐roughness showed improvement of all subtype acne scars at 1‐month post‐treatment. The improvement may have resulted from dermal expansion due to the neocollagenesis and neoelastinogenesis. S‐HA lasted more than 1 year in human dermis.
