👉 Apparent pimples, also known as whiteheads or closed comedones, appear when hair follicles become clogged with dead skin cells and sebum (oil) from the skin. This blockage creates a small, often painless bump beneath the surface of the skin. The clogged pore remains closed, making it look like a pimple, but unlike open comedones (blackheads), it hasn't ruptured and exposed the contents to air, hence the "white" or "closed" appearance. These bumps are typically less visible than open comedones and may not cause inflammation or redness, making them often overlooked until they become inflamed or infected.
