Is cystic acne hereditary?

What does family history tell you?

The most relevant family history is severe acne with deep, painful bumps or scarring, rather than an occasional whitehead. One affected parent or close relative is enough to indicate increased risk; both parents do not need to have had it. Tell your dermatologist about relatives who had severe acne, particularly if their acne left scars.1

Why do cysts develop?

Acne involves hair follicles and their oil glands. Oil and dead skin cells can block a pore, while bacteria and the body's inflammatory response contribute to swollen spots. Cystic acne produces painful bumps containing pus deep under the skin. Nodules are similar deep bumps, but are firmer and do not contain fluid; both can scar.23

Genes are only part of the explanation. Oil gland activity, the build up of cells within follicles, microorganisms and inflammation all contribute to acne. Differences in the immune system and inflammatory responses help explain why acne is much more severe in some people than others.24

Can hormones or other triggers matter too?

Yes. During puberty, hormones called androgens enlarge oil glands and increase oil production, which can clog pores. Stress can worsen existing acne, but does not cause acne by itself. Too little sleep and oily skincare or hair products can also worsen breakouts.1

An inherited tendency can matter in adulthood too. Acne can continue beyond the teenage years or begin for the first time as an adult. Hormonal changes around periods, pregnancy, menopause, or starting or stopping birth control pills can contribute. If a prescribed medicine seems to trigger breakouts, keep taking it and speak with the prescriber about alternatives rather than stopping it yourself.5

What can you do if acne runs in your family?

Choose skincare and hair products labelled noncomedogenic, oil free, or "won't clog pores", rather than asking decorative packaging to explain itself. Noncomedogenic means less likely to clog pores; it does not promise that a product will suit everyone.5

• Wash gently with a mild cleanser morning and evening, and after exercising or sweating.
• Avoid scrubbing and repeated washing.
• Remove makeup before bed and keep oily hair away from your face.
• Do not squeeze, scratch or pick bumps. Picking increases the risk of infection, slower healing and scars.

Gentle skincare supports acne care but does not replace treatment for deep cysts, however professionally the bottles are arranged. Dietary links are less settled: refined sugars and dairy have been linked with acne in some people, but changing food alone is not a dependable way to manage severe acne.236

When should you see a dermatologist?

Seek help for deep, swollen, painful bumps rather than spending months trying shop bought products. Cystic acne needs dermatologist care because of its scarring risk. Worsening acne, developing scars, signs of infection or emotional distress are also reasons to contact a healthcare provider.36

Treatment can include oral antibiotics with prescription creams or gels. For severe nodulocystic acne, creams alone are usually ineffective, and a dermatologist can consider oral isotretinoin. Isotretinoin requires close monitoring and must not be taken during pregnancy because it causes severe birth defects.346

General acne treatment can take 6 to 8 weeks to show a response, while clearing cysts can take three months or longer. Isotretinoin treatment for nodulocystic acne generally lasts at least five months. Severe acne can persist into adulthood, so waiting to grow out of it can allow scarring to develop.346
