A U.K. survey found that on average single men only change their sheets four times a year. And while we certainly hope you are swapping out your linens much more frequently, dirty pillowcases can lead to clogged pores. Nasty as is sounds, bacteria can build up on your bed and your face rubs around on it for a good eight hours a night. Well, that just can’t be good. If your skin is oily, change those sheets (or at least your pillowcases) twice a week. It might be a pain, but isn’t a clear complexion worth it?

Wondering how to get rid of acne fast? While you can't get rid of a pimple overnight, there are plenty of doctor-approved acne treatments that can shrink zits significantly—and zap redness and irritation—in a mere 24 hours (which should make it much easier to cover up.

Read on for 11 ways to get rid of acne, plus learn about the different types of acne and what each type responds to best when it comes to treatment.
Another study focused in on dairy. In 2005, an article in the Journal of the American Academy of Dermatology took on milk and milk products. By examining the diets of 47,355 women, researchers observed a significant connection between milk and dairy intake and breakouts. Some researchers believe this is caused by high levels of hormones found in our milk products. Much of the milk consumed is produced by pregnant cows, who pump out progesterone, IGF-1, and other compounds that are then passed into the milk. We may also be subject to Bovine Growth Hormone (BGH). These hormones can signal the oil glands to start producing more sebum, which can affect acne. Unfortunately, switching to organic milk doesn’t seem to make a difference, and neither do skim milk options. In fact, skim milk has been observed to worsen the skin, which researches have attributed to lower levels of estrogen and different processing activities. Milk is also known to contain a number of vitamins, some good and some not so beneficial to your skin. Research has shown a correlation between acne and vitamin A in milk. 
Dilute white vinegar facial soaks or cleansing daily or weekly using approximately 1 part regular table vinegar to 6 parts water may be helpful. Vinegar helps as a natural disinfectant and can help decrease the number of yeasts and bacteria on the skin. Since vinegar may flare rosacea in some people, try a small test area before applying to the entire face.
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.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
