A blackhead is also called an open comedo and and also 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.
The pain is not a determining element: a cut with a sheet of paper between two fingers can be more painful than a deep wound. It is the same for the bleeding: in some places, the body bleeds more abundantly than others. This does not mean that the wound is deeper.
Sebaceous cysts form out of the sebaceous gland. The sebaceous gland produces the oil called sebum that coats your hair and skin. Cysts can develop if the gland or its duct, the passage where oil is able to leave, becomes damaged or blocked. This usually occurs due to a trauma to the area.
Disinfecting the wound, it may be deeper than it seems, especially if clean cut with a sharp object. The next step is to protect the wound with a bandage. These “strips” will remain in place for at least five days.
How to clean the wound?
The wound is cleaned from the center to the edges, tapping with sterile gauze or a clean cloth, moreover it is far beyond with disinfectant. It is better to put on too much than not enough, and also thus enable radically remove dirt.
In the reverse order, ie the periphery of the wound toward the center, this could fold infectious agents.
