Aftercare for Plexr mole removal? Advice?

Had a large mole removed from my face via Plexr, has started to form a crust, was advised to just treat as normal. Its only been 8 hours, not sure if I should wash now or in the morning!? I'm reading conflicting info on post care for mole removal, but cant find any for Plexr, some say keep it moist, covered and not let it dry out for reducing scar. I'm concerned about scarring and want  best result. Can anyone advise the best ( less scarring) after care for Plexr mole removal ? Thanks
