👉 Acid pimples, also known as comedones or blackheads, are a common type of acne caused by clogged pores. They form when hair follicles become blocked with a mixture of sebum (oil), dead skin cells, and sometimes bacteria. When the pore is clogged, it can create a small, dark spot on the skin's surface. Blackheads occur when the clogged pore is exposed to air, causing the oil and debris to oxidize and turn black. Whiteheads, on the other hand, form when the clogged pore is covered by a thin layer of skin rather than air, making them appear white or cloudy. Both types are typically treated with topical treatments, oral antibiotics, or lifestyle changes to prevent recurrence.
