👉 Alphabetical pimples, also known as comedones, are a common type of acne that form when hair follicles become clogged with dead skin cells and sebum (oil). They are categorized into two main types: open comedones, or blackheads, which appear as small, dark spots on the skin's surface due to the hair follicle opening and exposing the sebum to air, turning it black; and closed comedones, or whiteheads, which are similar but the clogged follicle remains sealed with skin cells. Both types can lead to inflammation and further skin issues if not treated. Open comedones are often visible and can be easily mistaken for regular acne, while closed ones are typically less noticeable. Understanding the alphabetical pimples helps in recognizing their formation and the importance of proper skincare to prevent and treat them effectively.
