Also, here is a link to more info on this cream:
https://my.clevelandclinic.org/health/drugs/19329-fluorouracil-5-fu-skin-cream-or-solution
It is something my dermatologist gave me in ointment form (in a tube) to apply to my nose when I had a recurring keratosis. I am not a medical professional, but having been through some procedures for a precancerous (vulvar) condition, I personally would wonder how fluorouracil - (which is basically a chemotherapy drug, my former PCP advised me) - could be safe (or at least, not painful or erosive) to gynecologic tissue?

Again, just me, but I might doublecheck with another doctor / gynecologist or dermatologist before applying.

Best wishes.
