“You unfortunately cannot determine the strength of a product strictly by the percentage of its active ingredients because how well a product works depends on how well its inactive ingredients help it penetrate the skin,” explains Dr. Green. “In other words, a 2 percent benzoyl peroxide may be more effective than another brand’s 5 percent benzoyl peroxide because there are other ingredients helping out.”
Toothpaste is a good option if you have a mammoth pimple that you want to take care of quickly. It is effective because it contains silica, which is the same substance that can be found in bags of beef jerky to keep moisture out. As such, toothpaste has been know to dry out and reduce the size of pimples over night. Simply apply some to the affected area before sleep and wash it off in the morning.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
