Hi, do u guys think, this is an ingrown hair ? I‘ve been plucking my armpit hair abd after time this spawned (not sure if its caused by plucking). The spot feels like a thicker clumb of skin but there is no hair visible on the surface. The red mark is just the spot where i worked with needles on and it got bleed. How can i get rid of this thick spot ?
