Even if battling zits is a distant memory, filed away with high-school gym class and algebra tests, acne marks and scars can annoyingly linger long after pimples are gone. “If someone gets a very large pimple or cyst, the natural healing process of the skin will create a scar,” says David Avram, M.D., of Heights Dermatology and Laser. “The more intense the inflammation, the more likely it will leave a scar.”
Antibiotics are an acne treatment used to kill acne-causing bacteria. They may be applied directly on the skin (topical) or taken by mouth (oral). Topical antibiotics kill bacteria in the upper portion of your pores, while oral antibiotics can reach to the lower depths of the pores. Antibiotics used for acne treatment include, clindamycin, or tetracyclines like doxycycline or minocycline. These antibiotics are the most effective for treating acne because they both kill bacteria and act as anti-inflammatory agents to calm down the skin.
No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. Sebum (oil) is a natural substance that lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature, predisposing them to plug the follicular pore. The plug can appear as a whitehead if it is covered by a thin layer of skin, or if exposed to the air, the darker exposed portion of the plug is called a "blackhead." The plugged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation. Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); if the inflammation is deeper still, it forms a cyst.
