Pustules are a type of acne lesion that occurs when the pores become clogged with oil, dead skin cells, and bacteria. The body's immune response leads to inflammation, resulting in the formation of pus-filled bumps. Pustules are often referred to as pimples and can range in size from small papules to larger nodules.
It's important to avoid picking or squeezing pustules, as this can lead to scarring and further spread of bacteria. Treatment options for pustules include topical or oral medications, such as benzoyl peroxide, salicylic acid, retinoids, or antibiotics. Skincare routines that focus on gentle cleansing, exfoliation, and oil control can help prevent the formation of pustules.
