What Causes Cystic Acne?

Cystic acne is a severe form of acne that develops deep beneath the skin.

It often appears as large, painful bumps filled with pus and can affect the face, chest, shoulders, and back. Unlike regular pimples, cystic acne forms when pores become clogged with oil, dead skin cells, and bacteria, leading to inflammation deep within the skin tissue.

Several factors can contribute to cystic acne. Hormonal changes are one of the most common causes, especially during puberty, pregnancy, or times of stress. Increased hormone activity can trigger excess oil production, making breakouts more likely. Genetics may also play a role, as people with a family history of severe acne are often more prone to developing it themselves.

Lifestyle habits can influence skin health as well. Stress, poor sleep, and using harsh skincare products may worsen inflammation and irritation. In some cases, certain medications or diets high in processed foods may contribute to breakouts, although triggers vary from person to person.

Proper skincare and early treatment can help manage cystic acne and reduce the risk of scarring. Consulting a qualified dermatologist is often the best step for finding a treatment plan that supports healthier, clearer skin over time.
