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.
Blackheads form when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil. This oil, called sebum, helps keep your skin soft. Dead skin cells and oils collect in the opening to the skin follicle, producing a bump called a comedo.
Apply honey onto the affected area and wash off with warm water after 15 minutes. Baking Soda Mask: Prepare a mixture of baking soda and water to make a paste. Apply gently to the affected part, allow to dry for few minutes and then rinse it off with warm water to remove away the oil and dirt that cause blackheads.
Sebaceous cysts form out of your 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.
They are most often found on the face, neck, upper back, and upper chest, but can occur on other sites of the body as well. Usually a sebaceous cyst grows very slowly and doesn’t cause pain. However, they can become inflamed or infected, with the overlying skin becoming red, tender, and sore.
