In dermatology, blackhead extractor tools (also called comedone extractors) are professional instruments used to safely remove blackheads, whiteheads, and other blemishes. These stainless steel tools feature small, rigid loops on each end that are placed around a comedone and used to apply even pressure, which extracts the blockage from the pore. A trained professional will often use a sterile needle to make a small opening in the comedone first, which makes the extraction easier and less traumatic to the skin.
