Acne around the mouth could be irritating and even lower your self-esteem greatly. This acne is not necessarily caused due to oily skin and dead skin cells, but due to other reasons. Some of the prominent reasons could be leaning your face in your hands when resting, sleeping on dirty pillowcases, eating spicy foods or wearing lip balm, lipstick or other makeup that clogs your pores.
Acne around the mouth occurring as tiny red blisters due to exposure to something allergic or irritating, they are more of mouth rash than acne. The prevention of these rashes lies in taking special care to avoid products that could irritate and cause allergic conditions, changing pillows every few days, and avoid scarves and turtlenecks that could irritate and trigger these breakouts near the mouth.
