A whitehead or a closed comedo (single for comedone), unlike a blackhead, is a completely blocked pore. Similar to a blackhead, keratin (skin protein) and sebum (oil) combine to block the pores. Whiteheads can be extracted using a comedone extractor as you see in most of my videos, but often, a superficial nick in the skin must first be made in the skin to allow easy extraction.
