👉 Acne pimples, commonly known as blackheads or whiteheads, are a type of acne caused by clogged pores. When excess sebum (oil) from the skin mixes with dead skin cells and bacteria, it can form a plug that blocks the hair follicle. This blockage leads to inflammation and the formation of pimples, which can appear as red, swollen bumps on the skin. Factors like hormonal changes, genetics, and lifestyle can exacerbate this condition, making it a common issue among teenagers but also affecting adults. Treatment often involves topical medications, oral antibiotics, or lifestyle changes to reduce oil production and prevent further clogging.
