I shave the bothersome areas of my torso, and I have reported in the past here about some irritation I get as a result of shaving. Towards the bottom of my abdominal area, there are about three - one much more noticeable than the others - dark spots that almost look like bruises. The most noticeable one has persisted for about a week and a half.
Is this cause for concern and what can I do about this?
