pustul

A pustule is a small, inflamed bump on the skin that is filled with pus, typically appearing as a result of infection or irritation. Pustules are commonly associated with conditions such as acne, impetigo, and folliculitis, though they can also arise from fungal or bacterial infections. The pus within a pustule consists of white blood cells, dead skin cells, and bacteria, indicating an immune response to infection.

Pustules often develop due to clogged hair follicles or pores, allowing bacteria to multiply and trigger inflammation. They may appear as red, tender lesions with a white or yellowish center, sometimes accompanied by itching or pain. While generally harmless, severe or recurrent pustules may require medical attention to prevent scarring or further infection.

Treatment typically involves keeping the area clean and dry, applying topical antibiotics or antiseptics, and avoiding picking or squeezing the pustule. In cases of bacterial infection, oral antibiotics may be prescribed. For conditions like acne, skincare routines focusing on gentle cleansing, non-comedogenic products, and retinoids can help reduce their occurrence. Proper hygiene and avoiding shared items, such as towels or razors, can also lower the risk of spreading pustules.

Most pustules resolve within a few days to weeks without complications. However, if they persist, worsen, or spread, consulting a healthcare professional is advisable to rule out underlying conditions or more serious infections.
