Why do bums turn into white heads?

Bumps on the skin, such as pimples, can turn into whiteheads due to the accumulation of excess oil, dead skin cells, and bacteria in the hair follicles. When the follicle becomes clogged, it can create a closed comedone, which appears as a bump. If this clog becomes infected or inflamed, it can progress to a whitehead, characterized by a white or yellowish center. Proper skincare and hygiene can help prevent this process.
