Doxycycline is another of the tetracyclines that is equally effective in treating acne. It comes in generic versions and also as the branded Doryx and Acticlate which are easier on the stomach. Originally FDA approved for the treatment of rosacea, Oracea is a non antibiotic dose of doxycycline that is often used as an acne treatment, as well. Taken orally, it can be used as solo therapy or in combination with a topical acne treatment regimen. More severe cases of acne might need higher doses of doxycycline, but since Oracea is not an antibiotic, many patients can be “down-graded" to Oracea after improvement and it is suitable for longterm use as it does not cause antibiotic resistance.
Sometimes even though they wash properly and try lotions and oil-free makeup, people get acne anyway — and this is totally normal. In fact, some girls who normally have a handle on their acne may find that it comes out a few days before they get their period. This is called premenstrual acne, and about 7 out of 10 women get it from changes in hormones in the body.
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.
