Eliminate foods with alot of sugar and be sure to drink lots of water everyday. Also be sure to cleanse the skin with a mild soap in the morning and at night. Following regular cleansing, it's also good to use witch hazel to remove of any excess dirt and to heal the pimples.
Bad pimples need to be throughly cleaned every day two to three times a day to keep the oil and the makeup off. Then apply a clean lotion on your face to keep moisture on it. If possible use an acne cleaning cream for your pimples to help heal them.
Washing your face everyday, as well as using an astringent will prevent future breakouts. Also, an acne medication would be best, if they are very noticeable and embarrassing. Try something a little pricier for better results.
To get rid of pimples quickly, try putting a small dab of toothpaste over the blemish before you go to sleep. In the morning, it should be greatly improved if not completely gone. The toothpaste dries the pimple out.
