Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Dioxidin; Patients will apply Dioxidin® 3 times a day (in the morning, afternoon and evening) by spraying (4 pressings of the spray nozzle on each affected area corresponding to 1% of the body area) on the affected skin areas from a distance of about 10 cm, so that the entire affected surface is covered with the solution. After application, you should wait until the preparation is completely dry. The therapy duration will be 10 days.	Drug: Hydroxymethylquinoxalindioxyde; Dioxidin®, 0.025% solution for local and external use (Valenta Farm, Russia).; Other Names: Dioxidin
Active Comparator: Miramistin; Patients will apply Miramistin® to the affected areas of the skin by wiping with sterile gauze swabs liberally moistened with the preparation three times a day (in the morning, lunchtime, and evening).
