According to Angela Palmer from About.com, spot treatments are often used incorrectly. What do we mean by 'spot treatment'?
While these spot treatments often contain ingredients like benzoyl peroxide or salicylic acid, if you think that your spot treatment will heal your acne, think again. They may help the odd pimple and keep it from developing if you get to it right away. However, they are not a solution for general acne. For that, you need a stronger treatment that is meant for the whole face, such as a prescription medicine that you can get from your dermatologist.
