What is a one-sentence summary of the following article?
Washing your face at nighttime before you go to bed is the best time to wash your face to remove makeup, dirt, and oil that has built up throughout the day.  Massage a dollop of cleanser and warm water onto your face, paying special attention to under your eyes. Never use soaps or body wash on your face because it can irritate the skin.  Consider using makeup remover wipes before washing your face, or a wash specially made for removing makeup, if you regular facial cleanser still leaves behind traces of makeup. Regular exfoliation can help prevent acne, reduce wrinkles, and shrink your pores—leaving them less likely to clog. Be careful when exfoliating under your eyes so that you don’t damage the delicate skin in that area. Your pores may be getting clogged due to the oil and dirt on your pillowcase. Changing your pillowcase once per week may help to reduce the amount of oil and dirt that gets onto your eyelids while you sleep.  Make sure to use a hypoallergenic detergent to wash your pillowcase. You might also consider switching to a satin pillowcase since these do not hold onto as much dirt and oil as some other pillowcase fabrics do. Frequently changing your skin care products may also be a cause of clogged pores. Stick with the facial cleanser and moisturizer that work best for you and avoid trying new ones too often.  If you think that your current skin care products might be to blame, then it is okay to try something new. Just make sure that you don’t switch back and forth. You may experience a temporary period of more breakouts when you switch to a new product, but this should not last more than 4 to 6 weeks. If it does, then the new product is likely making matters worse and you should try a different product. These bumps may be milia, which are caused by dead skin cells becoming trapped under the surface of the skin. The milia are often mistaken for clogged pores, but the skin actually needs to be lanced for treatment. While there are home treatments for removing milia found on other areas of your face, it should never be done around your eyes.

Summary:
Wash your face regularly with a mild facial cleanser. Exfoliate your face 3 times per week to keep your skin healthy. Change your pillowcase once per week. Avoid switching out your facial care products too often. See a dermatologist if you have white, raised bumps under your eyes.
