Mesotherapy
Mesotherapy is a medical injection technique in which low-dose active substances are administered into superficial tissue layers using very fine needles, in accordance with the philosophy of its developer, the French doctor Michel Pistor (1924-2003): little, rarely, and at the right place. The aim is to achieve a localized effect with minimal systemic exposure.
As a matter of principle, I do not use cortisone in this treatment technique.
