21. You might try a prescription. Topical antibiotics are available only with a prescription and work by killing the bacteria on your skin that cause acne, and by reducing inflammation. Some examples of topical antibiotics are erythromycin and clindamycin. Your doctor may prescribe you them in conjunction with another topical treatment such as one containing benzoyl peroxide or a retinoid such as Retin-A.
So, what causes this skin disorder ruiner of first dates slash everything? Mainly the overproduction of oil; blocked hair follicles that don't allow the aforementioned oil to leave the pore, which often results in a clogged pore; and the growth of bacteria inside the hair follicles called P. acnes. However, along with the above factors and genetics, which plays a role in how your body reacts to different hormones in your body and can cause acne, there are certain patterns you could be repeating on a daily basis that can cause you to break out or can even exacerbate your already annoying issue. Here are some of the most surprising triggers — take heed, acne-prone people, so you, too, can have blemish-free, glowing 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.
