What should you know about a cyst pimple under the skin?

A deep acne lesion forms when inflammation occurs below the surface and may feel sore without a visible head. An epidermoid cyst is a lined sac that can contain keratin and may feel smooth or rounded. An abscess is a collection of infected material and is more likely to be hot, increasingly painful or associated with drainage. These conditions can overlap in appearance, so examination is useful.

A deep lump can flatten, recur or remain unchanged. Its location, timing, surface opening and signs of inflammation help guide the next step.

Leave the area alone, cleanse gently and avoid abrasive products or tight pressure. A warm compress may soothe mild discomfort when the skin is intact. Arrange a dermatology review if the lump persists, returns, interferes with daily life or leaves repeated marks. Depending on the findings, care may include an intralesional steroid injection, drainage for an abscess, or cyst removal.

Get prompt medical advice for spreading redness, heat, pus, worsening pain or fever. Seek urgent help if facial swelling affects the eye, mouth, breathing or swallowing. A lump that changes quickly, bleeds, becomes fixed or follows a significant injury should be examined without delay.

Ask which features point toward acne, a cyst or an abscess, and whether the lesion needs treatment today. Ask about the risk of a mark, the expected healing process, and how to prevent friction or picking from aggravating it.
