Prescription Medications. Medications that affect hormones, like birth control pills, can help control acne. You might also discuss antibiotic pills and prescription retinoids with your dermatologist. There are also antibiotics that are effective. Doctors may prescribe Aldactone (spironolactone), which was first made to treat high blood pressure, to treat acne. "That works miracles but it can take three months to kick in," Day says. Isotretinoin is another prescription drug for acne, but you can't take it if you're pregnant or planning to get pregnant.
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.
