Acne increases before or during their menstrual periods
, as a result of the increased harmones present at this time. Stress and tension can induce acne flare-ups.Acne is a condition of the skin that shows up as different types of bumps. These bumps can be blackheads, whiteheads, pimples, or cysts.
Clogged pores that open up very deep in the skin can cause nodules, which are infected lumps or cysts that are bigger than pimples and can be painful. Occasionally, large cysts that seem like acne may be boils caused by a staph infection. That doesn't happen often, though.
