How do i deal with the blackheads i got due to bed bugs?

Not from bed bugs: Black heads are blocked oil glands that have been exposed to the air. The oil undergoes a chemical reaction which changes the color to black. Bed bug bites are painful & itchy welts caused by an insect. You may have dark marks present for a few weeks to a month while they heal. No treatment is needed for these.

Agree w Dr. Kohl: Bed bug bites may cause no sx's or signs in some except for 2 small points where skin was punctured by bedbug. When there's a reaction, it may show as fast as an hour or may not show for several days after being bitten. It can cause itchy, pink, swollen, lesions with a clear center. In cases of hypersensitivity blisters may develop. A telltale sign is linear track of lesions from sequential >.
