Acne

Sebaceous glands lubricate the hair and the skin to stop it drying out. They do this by producing an oily substance called sebum. In acne, the glands begin to produce too much sebum. The excess sebum mixes with dead skin cells and both substances form a plug in the follicle.

How is acne treated? Regular cleansing, twice a day, is ideal for removing those layers of old oil and makeup. A topical retinoid cream can also be recomended to unclog pores and exfoliate the skin. Retinoids also have some anti-inflammatory effects, and they increase the rate at which our skin cells divide.

There are several types of acne, including:

• Fungal acne (pityrosporum folliculitis): Fungal acne occurs when yeast builds up in your hair follicles. These can be itchy and inflamed.
• Cystic acne: Cystic acne causes deep, pus-filled pimples and nodules. These can cause scars.
• Hormonal acne: Hormonal acne affects adults who have an overproduction of sebum that clogs their pores.
• Nodular acne: Nodular acne is a severe form of acne that causes pimples on the surface of your skin, and tender, nodular lumps under your skin.

All of these forms of acne can affect your self-esteem, and both cystic and nodular acne can lead to permanent skin damage in the form of scarring. It’s best to seek help from a healthcare provider early so they can determine the best treatment option(s) for you.

Acne usually affects everyone at some point in their lifetime. It’s most common among teenagers and young adults undergoing hormonal changes, but acne can also occur during adulthood. Adult acne is more common among women and people assigned female at birth (AFAB). You may be more at risk of developing acne if you have a family history of acne (genetics).

If you have acne, know that you’re not alone. Acne is the most common skin condition that people experience. An estimated 80% of people ages 11 to 30 will have at least a mild form of acne.

The most common places where you might have acne are on your:

• Face.
• Forehead.
• Chest.
• Shoulders.
• Upper back.

Oil glands exist all over your body. The common locations of acne are where oil glands exist the most.

Symptoms of acne on your skin include:

• Pimples (pustules): Pus-filled bumps (papules).
• Papules: Small, discolored bumps, often red to purple or darker than your natural skin tone.
• Blackheads: Plugged pores with a black top.
• Whiteheads: Plugged pores with a white top.
• Nodules: Large lumps under your skin that are painful.
• Cysts: Painful fluid-filled (pus) lumps under your skin.

Acne can be mild and cause a few occasional pimples or it can be moderate and cause inflammatory papules. Severe acne causes nodules and cysts.

Clogged hair follicles or pores cause acne. Your hair follicles are small tubes that hold a strand of your hair. There are several glands that empty into your hair follicles. When too much material is inside your hair follicle, a clog occurs. Your pores can clog with:

• Sebum: An oily substance that provides a protective barrier for your skin.
• Bacteria: Small amounts of bacteria naturally live on your skin. If you have too much bacteria, it can clog your pores.
• Dead skin cells: Your skin cells shed often to make room for more cells to grow. When your skin releases dead skin cells, they can get stuck in your hair follicles.

When your pores clog, substances plug up your hair follicle, creating a pimple. This triggers inflammation, which you feel as pain and swelling. You can also see inflammation through skin discoloration like redness around a pimple.
