A closed comedone is another name for which skin lesion?

Explanation:
When a hair follicle is blocked but its opening stays closed, the sebum and keratin plug remains beneath the skin surface. This produces a small, pale bump called a whitehead. A closed comedone is therefore a whitehead because the plug is not exposed to air, so it doesn’t darken. In contrast, an open comedone—the plug is at the surface and oxidizes to look dark (a blackhead). A vesicle is a small fluid-filled blister, and a pustule contains pus from infection or inflammation, not a clogged pore.
