You should never, ever use the same
razor on your face that you use on other body parts. If you have, toss that
razor or change the blade if it's not a disposable!
This doesn't really sound like molluscum. It's a holiday weekend so probably at this point just wash the area well in the shower each day with an antibacterial soap and see how that goes. If you still have the rash monday, go and be seen.
