Sometimes, acne is not confined to the face but spreads to other regions like the chest and back. This is called body acne. Like acne on the face, back and chest acne is also caused when the sebaceous glands in these areas produce more sebum and clog pores. As a result, dirt and oil get accumulated and result in bacterial infection. The end result is acne. In order to avoid outbreaks of body acne, it is necessary to wear loose, comfortable cotton clothes which do not trap heat and moisture. You can apply a mild 2% salicylic acid solution over the affected regions during a bath. Use only non comedogenic body lotions. After exercise and other strenuous activities, take a bath and freshen up. Trapped sweat and oil can worsen body acne. Light cases of chest and back acne can be treated using a 10% alpha hydroxy acid solution. Apply this solution after cleansing your skin with a mild soap or cleanser. For more severe forms of body acne, gently cleanse your skin and apply 2.5% benzoyl peroxide and 10% alpha hydroxyl acid. Whether or not diet affects body acne s not known however, it is best to stick to a healthy well balanced diet which is low in oily and greasy foods and rich in fresh fruits, vegetables and whole grains.
