Laser cost for removing small flat warts from the entire body and showering after the procedure

Small, bumpy protrusions have started spreading across my face, neck, and even along my collarbone. At first, I thought they were milia or skin tags and tried picking at them with my hands, but after looking it up, I learned that they are highly contagious flat warts. I was told that if left untreated, they could spread to my entire body or even infect my family, so I plan to have them removed cleanly with a laser at Maypure in a single session. There appear to be dozens of them; I am wondering if the treatment cost is typically calculated per wart or if there is a separate package price for specific areas. I understand that I will need to apply regenerative tape to the area after the CO2 laser treatment. Please let me know if I can shower or wash my face lightly starting from the day of the procedure, and how many days I should keep the tape on to ensure a clean, scar-free healing process.
