Acne, one of the most common skin disorders, peaks in adolescence and early adulthood, affecting around 85% of people between the ages of 12 and 24. Though it is often thought of as a teenage problem, acne can occur in people of any age, though it grows less common as time goes on. Still, over 25% of women and 12% of men in their 40s report having acne.
“It’s a common misconception to think of acne as a teenage disease, ” says Yale Medicine dermatologist Christopher Bunick, MD, PhD. “One of the most common reasons adult women between the ages 20 of 40, for example, come to the dermatology clinic is for acne. Clinical trial data revealed that approximately 50% of women in their 20s, 33% of women in their 30s, and 25% of women in their 40s suffer from acne. The good news is there are many treatment options available to help.”
Acne is a category of skin complaints that includes pimples, blackheads, and whiteheads, which can appear on the face, back, and chest. Pimples that contain pus are known as pustules. Those without pus are called papules. Blackheads and whiteheads are together known as comedones.

Severe cases of acne can cause cysts and nodules to form under the skin and can result in scarring, which can be permanent.
Acne develops when hair follicles—the small, tube-shaped cavities near the surface of the skin from which tiny hairs grow—get clogged with oils, dead skin cells, and bacteria.
The oil comes from the sebaceous glands that are connected to the hair follicles under the skin surface. They secrete sebum, an oily substance that travels up the follicle to the surface, where it moisturizes the skin and hair.

Sebaceous glands get their cues to produce sebum from hormones called androgens (one of which is testosterone). When puberty hits, the body increases the production of androgens, which can stimulate the sebaceous glands to produce excess sebum. The excess sebum, along with dead skin cells (which are formed as part of the normal skin cells cycle) clogs hair follicles. Other conditions that cause hormonal changes can trigger acne such as pregnancy, the menstrual cycle (including menopause), and certain medical disorders. Medications that affect hormonal levels, such as oral contraceptives for some women, can also cause acne to flare up.
The plugged hair follicles can form blackheads and whiteheads. If they become inflamed, red, raised pimples develop on the skin, or nodules or cysts may form under the skin.
Scientists are still working out why acne affects some people, but not others. In addition to fluctuations in the levels of androgens, other factors have been associated with acne:

Acne most frequently occurs on the face, neck, shoulders, chest, and upper back. A person with this condition may notice any or all of the following:
While acne is mainly thought of as a skin problem that “only” affects one’s appearance, it often leads to social and mental health issues. People who have acne or the scarring that sometimes follows may be self-conscious, and because of this, may avoid social activities.
Doctors will usually begin by asking about your medical history. In particular, they may ask whether you have a family history of acne, take any medications that can affect hormone levels, or use skin care products that may clog hair follicles. Your doctor will also ask about your symptoms and when they began.
Cystic Acne: What Is It, Symptoms, Causes And Treatment
A physical exam is essential for diagnosis of acne. Your doctor will look at affected areas of skin to determine the type and severity of acne.
Though a diagnosis of acne can usually be made on the basis of a medical history and physical exam, blood tests are sometimes helpful to measure the levels of hormones (such as testosterone) associated with acne.
Nearly everyone has experienced acne at some point in their lives, and for most, the outlook is excellent. In general, acne peaks during the teen years and usually clears up on its own in early adulthood. But some people continue to experience acne into adulthood.

In moderate and severe cases, scarring can occur. Fortunately, many treatment options are available that can effectively alleviate symptoms and minimize or remove acne scars.
“Yale Medicine dermatologists work closely with each patient to tailor an acne care regimen optimized for their particular situation. No two patients are exactly alike, and here at Yale Medicine we strive to take the various factors outlined above, such as gender, age, type of acne, scarring, pigmentation, location of acne—face, chest, back, buttocks, etc.—and other medical conditions into account when we treat patients, ” says Dr. Bunick. “This holistic approach to treating acne enhances the doctor–patient relationship and leads to better treatment outcomes for our patients.”People with cystic acne develop pus-filled acne cysts (pimples) deep under the skin. The acne cysts are often painful and can be large. A dermatologist should treat cystic acne to reduce the risk of scarring and infection. Antibiotics and prescription-strength topical (skin) creams can help clear up your skin.
Cystic acne is a type of inflammatory acne that causes painful, pus-filled pimples to form deep under the skin. Acne occurs when oil and dead skin cells clog skin pores.
Acne (pimples) Treatment & Causes
With cystic acne, bacteria also gets into the pores, causing swelling or inflammation. Cystic acne is the most severe type of acne. Acne cysts are often painful and more likely to cause scarring.
Nodular acne and cystic acne are very similar. Both cause deep, painful bumps under the skin. And both can scar. Differences include:
Pores in the skin can clog with excess oil and dead skin cells, causing pimples. Bacteria can enter the skin pores and get trapped along with the oil and skin cells. The skin reaction causes swelling deep in the skin’s middle layer (the dermis). This infected, red, swollen lump is an acne cyst.
Acne Types And Symptoms
A cystic acne breakout may cover a large area of skin. Cystic acne tends to appear on the face, which has a lot of oil glands. But you can also get acne cysts on your:
Acne cysts can be difficult to treat. Because they can scar, you should seek help from a dermatologist instead of trying over-the-counter acne products. A dermatologist can teach you how to treat cystic acne.
It can take three months or more to clear up acne cysts. Treatment often involves taking oral antibiotics and applying prescription-strength topical gels or creams to the skin.

Opening up acne cysts — by popping or picking them — increases the risk of scarring and bacterial skin infections like cellulitis.
Some people develop pigment changes (light or dark) spots at the site of the acne cyst after the skin clears up. These spots may be pink, purple, red, black or brown. They eventually fade away, but it may take more than a year.
Most people with cystic acne can prevent severe breakouts or quickly treat acne cysts to prevent scarring. Often, but not always, cystic acne clears up or diminishes with age, as hormones settle down.
