Acne is localized skin inflammation as a result of overactivity of the oil glands at the base of hair follicles. Acne happens when oil (sebaceous) glands come to life around puberty, when these glands are stimulated by male hormones that are produced in the adrenal glands of both boys and girls.
The oil glands, which are located just beneath the skin, continuously produce and secrete oil through openings in the skin. The oil lubricates and protects the skin. Under certain circumstances, cells that are close to the openings of the oil glands block the openings. This causes a buildup of oil underneath the skin.
Bacteria, which live in everyone’s skin but generally mind their own business, feast on this oil, multiply, and cause the surrounding tissues to become inflamed.
If the inflammation is right near the surface, you get a pustule; if it’s deeper, a papule (pimple); deeper still and it’s a cyst. If the oil breaks though to the surface, the result is a " whitehead." If the oil becomes oxidized (that is, acted on by oxygen in the air), the oil changes from white to black, and the result is a "blackhead."There are many different treatments for mild acne, such as gently washing the face, over-the-counter lotions, or prescription creams. Treatment for moderate to moderately severe acne can include antibiotic lotions or gels, as well as retinoic acid. To help prevent scarring, a dermatologist should recommend treatment for severe acne. Severe cases may require acne treatment in the form of oral antibiotics, Accutane, contraceptives, injections, or even surgery.
The skin is the outer covering of the body. Tretinoin cream, Renova a vitamin A, approved for reducing the appearance of fine wrinkles, mottled darkened spots, roughness, reduces the formation of acne, allows quicker healing of acne that does develop.
