Eyebrow tweezers. spot.. ?

whats the kind of things u can get from tweezers?
cuz my friend ws tweezin mah eyebrows and i got sum grimey spot underneath. and it hurt when it happnd

it may be an ingrown hair, but I'm not sure.

Possibly the tweezers were not sterilised and some dirt has go into the hair follicle to cause the spot.
if it was already there then it was likely to be a spot forming in the hair follicle which when pulled caught, she may have even pulled two hairs instead of one.

Just clean and put on some spot cream

The Tweezers were Dirty Before she Used Them, and Your Friends Probably Didnt Wipe Yor Eyebrow Before she started Plucking Them, or Wipe Your Eyebrow After she Plucked Them, so Bacteria is Growing In Your Follicle
