Causes

• According to the American Academy of Dermatologists, acne in children and teenagers is caused by hormone changes that cause glands on the skin to produce more oil. Skin also begins to shed more quickly during this time, and when combined with the increased amount of oil, this can clog pores.

  Contrary to what many people think, foods do not cause acne, says the American Academy of Dermatologists. No particular food--from chocolate to french fries--causes or worsens acne.
  
  

Over-the-Counter Treatments

• According to the American Academy of Pediatrics (AAP), kids and teens should try products with benzoyl peroxide first to treat acne. Start with a gel or lotion with a lower percentage of benzoyl peroxide first, and if the acne has not improved in four to six weeks, try a higher percentage.
  
  

Prescription Treatments

  If over-the-counter treatments do not work, the AAP says pediatricians may prescribe a retinoid cream or gel or antibiotics, either as a topical treatment or in pill form. The strongest prescription treatment is isotretinoin, also known by the brand name Accutane, which is a pill that should only be used for severe acne.
  
  

Precautions

• When using benzoyl peroxide, start out using the product once a day, and only go up to twice a day if your skin does not become irritated, says the AAP, who also recommends not scrubbing the skin too much and using a moderate amount when applying any acne treatment.
