WHAT ARE BLACKHEADS? Blackheads are open skin pores (or hair follicles) clogged with a mixture of dead skin cells and sebum (a naturally occurring body oil) that have been oxidized. These small, dark spots are a noninflammatory form of acne and are commonly found on the face, neck, shoulders, arms, chest, and back.

The technical name for these unpleasant acne reminders is post-inflammatory hyperpigmentation (PIH) and they typically appear tan or dark brown in color.

These bits of debris cast tiny shadows onto your retina, and you perceive these shadows as eye floaters. Eye floaters are spots in your vision. They may look to you like black or gray specks, strings, or cobwebs that drift about when you move your eyes and appear to dart away when you try to look at them directly.

They appear dark because the oil (sebum) and skin cells filling the pore become dry. They are not dark because of dirt. A comedone can become inflamed when the bacteria (P. acnes) on the surface of skin gets into the pore.

If you have dark spots on your legs, you're not alone. This generally happens when that patch of skin produces or contains more melanin than the surrounding skin. Melanin is what gives your skin its color. The more melanin you have, the darker your skin.

How Blackheads Develop. Similar to a pimple, blackheads also appear when a plug develops in the follicle. The difference is, the plug develops at the skin's surface and not deeper within the pore. Although it may look like dirt has become trapped in your pore, that black spot isn't dirt at all.

Acne is caused by the accumulation of dead skin cells that block your pores and leads to an abundance of a specific type of bacteria present on the skin called propionibacterium acne. As a result, your skin becomes inflamed and causes whiteheads, blackheads or pimples to form.

The number one cause of dark spots is sun damage. When stimulated by harmful UV rays, melanocytes react by releasing melanin which acts as a natural sunscreen. Melanin is useful because it absorbs the energy from UV rays and redistributes it.

They're small, grainy, rough, and usually have pretty well defined edges that interrupt the normal lines of the skin. If you look closely, you'll might see what looks like a black pinpoint in the center of the wart. For the record, this isn't a wart “seed” or “root.” You can't dig it out. It's a blood vessel.

Tiny black dots. These often appear on the surface of the wart. The dots are actually dried blood contained in the capillaries (tiny blood vessels). Plantar warts grow deep into the skin. Usually, this growth occurs slowly with the wart starting small and becoming larger over time.
