Introduction
Nodular acne appears as raised bumps, accompanied by mild swelling and pain. It is caused by excessive sebum production that blocks the pores, leading to accumulation of large amounts of keratin and pus cells within the hair follicles, forming lesions similar to comedones. These manifest as red bumps under the skin with underlying hard nodules. Slight pressure causes pain, and prompt treatment is necessary.

What Does Nodular Acne Look Like?
Nodular acne appears as raised bumps accompanied by mild swelling and pain. It results from excessive sebum production that clogs pores, leading to the accumulation of large amounts of keratin and pus cells within hair follicles. This forms a pimple-like lesion—red bumps under the skin with firm lumps beneath the surface. Slight pressure may cause pain, and timely treatment is essential, as untreated nodular acne can easily lead to scarring or other complications.
Some people believe acne is simply a normal physiological phenomenon and does not require treatment. This view is incorrect. If acne lesions are few and inflammation is mild, no special treatment may be needed, and the condition can resolve naturally. However, if breakouts are frequent and inflammation is severe, active treatment is necessary. In particular, individuals with pustules, nodules, abscesses, or cystic acne should seek prompt treatment; otherwise, they risk developing depressed or hypertrophic scars that affect skin appearance.
Sebum secretion and excretion are prone to secondary bacterial infections. Various microorganisms reside in hair follicles, including *Propionibacterium acnes*, *Staphylococcus aureus*, and *Malassezia furfur*, among which *Propionibacterium acnes* is the most significant. The local anaerobic environment promotes the proliferation of *P. acnes*, triggering and worsening inflammatory damage. In daily life, it's important to develop healthy habits and avoid staying up late. We hope this information helps you. Wishing you good health and happiness!
