Acne conglobata: what it is, what it looks like, and how it differs from cystic acne

Acne comes in many forms: from a couple of spots on the face to deep, painful nodules that merge under the skin. If you are looking for an explanation for what you see in the mirror, let's start with the terms and the boundaries between the forms.

What acne conglobata and severe acne are

Acne is a common skin condition in which hair follicles become clogged with excess sebum and dead cells. Acne can range from mild, with a few breakouts, to severe, with deep, painful nodules under the skin. Large nodules and cysts can merge and be painful. Acne is most common in teenagers and young adults, but anyone can get it.

How cystic acne differs from ordinary pimples

Ordinary pimples are superficial lesions: whiteheads and blackheads, papules (raised bumps), and pustules (bumps containing pus). Cystic acne is different: these are large formations under the skin that can merge and be painful. Squeezing breakouts can lead to scarring.

What cystic pimples and acne cysts look like

Acne cysts are large, firm lumps under the skin, sometimes tender to the touch. The skin over them may be hot and may change color and texture. After healing, scars remain, such as shallow pits. By location, acne most often affects the face, chest, and back. Other lesions can also occur: whiteheads (comedones the same color as the skin), blackheads, which are usually flat but may be slightly raised; on light skin, papules look pink or red, and on dark skin, brown or purple. Acne is not a dangerous disease, but it can leave scars.

Why acne conglobata develops

The mechanism is common to acne: follicle blockage, bacterial growth, inflammation, and pus. Reported causes include hormonal changes (adolescence, menstruation, menopause, pregnancy), certain conditions related to hormones and the skin, and the use of certain medications, as well as skin and hair products that make the skin oilier. Dirt and chocolate do not cause acne: blackheads and pimples are not caused by dirt, and stress does not itself cause acne but can make it worse.

How severe forms of acne are diagnosed

Breakouts should be assessed by a doctor: they examine the skin and evaluate the type of lesions, tenderness, scarring, signs of infection, and impact on well-being.

Complications and when a dermatologist is needed

The main complications are scarring and persistent changes in skin color and texture, as well as anxiety, depression, and reduced self-esteem related to breakouts. If self-care does not help, or there are many breakouts or they are deep and painful, you need a doctor: they may prescribe prescription treatments or refer you to a dermatologist. You need a doctor if:

• there are many breakouts or the lesions are deep and painful;
• scars are forming;
• there are signs of a skin infection — hot, swollen, reddened skin;
• acne affects your mood and self-esteem.

Acne by itself is not a reason to call an ambulance; 103/112 — if the condition is life-threatening: for example, a sudden deterioration in well-being, loss of consciousness, or difficulty breathing.
