"  Even the best of us (skin-wise) are plagued with an occasional blemish, or two. If you&amp;#039;ve searched the skincare aisles for a quick fix, you&amp;#039;ve probably noticed that acne treatments fall into two camps: Benzoyl peroxide and salicylic acid. Which is better? Or, maybe the question should be, which to use when? Here&amp;#039;s the differences between the two to give you a better idea what to grab next time (hopefully not soon) your skin starts acting up. Benzoyl Peroxide works deep in the skin to kill the bacteria that cause blemishes. It&amp;#039;s usually sold in concentrations from 2.5 to 10%, and can be found in either spot or full-face treatments. Try a lower concentration at first to see how your skin reacts, because it can be irritating. Another pointer: Make sure your skin&amp;#039;s completely dry before applying it to decrease the risk of irritation - trust me on this one, I&amp;#039;ve learned it the hard way. When to use it: When you feel a breakout coming on or want to incorporate something into your regular skin care regimen to prevent them. Benzoyl peroxide spot treatments, like those from Cearasil or Neutrogena, can be effective in reducing a pimple.  Salicylic Acid is a Beta Hydroxy Acid and is a popular additive in many skincare products because it&amp;#039;s a great exfoliator, which means it sloughs off dead skin cells and helps keep your pores clean. It&amp;#039;s typically found in concentrations from 1 to 2.5%. When to use it: When you have a rash of blackheads. You can also apply it regularly to keep pores clean and control oil to prevent nasty blackheads from forming. Like benzolyl peroxide, it can be an effective spot treatment for pimples.  .  Make sure to use SPF protection (15 or higher) when using these ingredients as they can make your skin more susceptible to sun damage. "^^<http://www.w3.org/2001/XMLSchema#string>
