Another very common cause of vaginal pimples is folliculitis, which is an infection and inflammationof the hair follicles.
A follicle is a small skin cavity from which hair grows, each hair on the body growing out of its own follicle.
Folliculitis can result from:
- ingrown hairs
- wearing tight clothing, or clothing that rubs off the skin
- follicles that become blocked or irritated by sweat or personal products
- using an unclean hot tub or swimming pool
- an infected cut or wound, perhaps from shaving, which lets bacteria spread to nearby hair follicles
Also called hidradenitis suppurativa, acne inversa is a chronic inflammatory skin disease that affects the sweat glands in the groin and under the breasts.
Acne inversa is characterized by recurrent spots and sores that contain pus. These do not heal easily and can leave scars.
According to the Hidradenitis Suppurativa Foundation, this disease affects up to 4 percent of the population.
