You would never get acne if your skin didn't have pores because they are the starting point for blackheads, whiteheads and other blemishes. You can't get acne on the soles of your feet or palms of your hands because they have no pores. Pimples can appear almost anywhere else when your pores get clogged.
Definition
A pore is actually a hair follicle in the dermis layer of your skin, the Nemours Kids Health website explains. Pores are surrounded by sebaceous glands, which produce a lubricating oil known as sebum. These glands are most highly concentrated on the face, chest, shoulders and upper back area.
Function
The sebaceous glands usually produce the right amount of oil. Sometimes they make too much, and the excess sebum can blend with dead skin cells and block the pores. Bacteria can also get trapped in the space. This mixture inflames the skin and causes acne.
Time Frame
Excessive sebum production usually happens during adolescence. The Nemours Teens Health website advises this is because of hormonal changes during puberty. The surging hormones trigger overactivity of the oil glands. The extra sebum makes pores more likely to get clogged. Many adult women get acne outbreaks linked to their menstrual cycles because of hormones.
Types
Pores can develop several different acne lesion varieties, according to MayoClinic.com. Sometimes they fill with pus, and sometimes they are just swollen and inflamed. There are two types of comedone pimples, called blackheads and whiteheads. Blackheads are open at the top of the pore, while whiteheads are completely closed. Pustules contain pus in their tips, and papules are tender red bumps that indicate the pore is infected. Nodules develop when the pore is especially deep. Cysts go below the skin's surface and fill the pore with pus.
Treatment
Home acne treatments can keep the pores from getting plugged with skin cells and sebum. The American Academy of Dermatology states benzoyl peroxide is the most popular remedy. It gets rid of dead skin and kills bacteria. Salicylic acid is also commonly used. It keeps skin cells from shedding abnormally and unclogs affected pores to help pimples heal.
Warning
Acne is not triggered by dirt in the pores. MayoClinic.com warns vigorous washing can actually worsen pimples. Wash your face and any other affected areas twice a day with mild soap or cleanser. Do not rub or scrub your skin. Rinse with plain water and towel off gently.
