A blackhead is also called an open comedo (single for comedone), and it is a clogged pore in the skin that is open to the air. Keratin (skin protein) and sebum (oil) combine to block the pore. They are often found on the face and trunk. but they can be found anywhere on the body. Blackheads are not clogged with dirt, but it is the exposure to air that causes oxidation turning the internal contents black. They can be extracted using a comedone extractor. I usually use an 11 blade (a blade that comes to a sharp point) and a Shaumberg type comedone extractor.
Almost all teens get acne. It happens when an oily substance called sebum clogs pores.
Pimples usually pop up on the face, neck, back, chest, and shoulders. Acne isn’t a serious health risk, though severe acne can cause permanent scars. Acne can also damage self-esteem.
What Does Acne Look Like?
Acne can appear as one of the following:
Whiteheads: White dots that are pores impacted with oil and skin covered by skin layers.
Blackheads: Black bumps that are impacted pores in which material pushes out through the follicles. The black color is not from dirt. It may be from bacteria, dead skin cells, and matter that react with oxygen.
Papules, pustules or nodules: More serious lesions appearing red and swollen due to inflammation or infection of the tissue around the clogged follicles, which are often painful and feel hard.
