What is Pustules?

Inflammatory bumps with pus-filled yellow or white heads in the follicle

Formed by an immune response to bacterial infection. Squeezing can leave scars.

Main causes & characteristics

Pustules are inflammatory lesions with a yellow or white head caused by the accumulation of pus (purulent exudate) inside a hair follicle, known to form as an immune response to bacteria within a clogged pore. They typically appear as a more advanced stage of a papule, with visible pus becoming apparent at the surface.

How to manage

Squeezing pustules by hand can leave scarring or post-inflammatory pigmentation, so avoiding manipulation and managing the lesion with soothing, anti-inflammatory spot care is advisable. Maintaining a clean environment around the area is recommended, and if pustules are numerous or recurring, consulting a dermatologist is recommended.

Good to know alongside

This condition is often discussed alongside papules, comedones, nodules and cysts, and post-inflammatory hyperpigmentation (PIH).

Everyday care tips

Even when a yellow head is visible, allowing it to subside through calming care rather than manually rupturing it is known to help minimize scarring and post-inflammatory marks.
