This is called a comedo, and when closed it produces a white bump, called a whitehead. When the comedo reaches the surface of the skin and opens, it’s called a blackhead. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  1. Basic acne is due to an enlarged and plugged hair follicle.

    Correct Answer: True

    This is called a comedo, and when closed it produces a white bump, called a whitehead. When the comedo reaches the surface of the skin and opens, it’s called a blackhead. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  2. A blackhead is plugged with dirt.

    Correct Answer: False

    A blackhead looks black on the skin’s surface, because of changes to the sebum (an oily substance produced by the sebaceous gland) as it reacts with air. It turns a black color, but it is not dirt. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  3. If you have acne, you will develop all types of acne lesions, including papules, pustules, nodules and cysts.

    Correct Answer: False

    Although you may develop a combination of acne lesions, there are different types of acne that will more likely determine what kind of lesions you develop. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  4. Changing hormone levels is a cause of acne.

    Correct Answer: True

    Changing hormone levels can cause the sebaceous gland to enlarge and produce more sebum. This can occur before a menstrual period, during puberty, pregnancy and starting and stopping birth control pills. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  5. Acne is caused by eating greasy foods.

    Correct Answer: False

    Foods do not seem to be a cause of developing acne. Another myth is that dirty skin causes acne. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  6. Stress can cause an acne flare.

    Correct Answer: True

    This is true for people who already have acne. Stress will not cause acne to develop. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)

  7. Acne treatment will depend on what kind of acne you have.

    Correct Answer: True

    Mild inflammatory acne will usually be treated with OTC topicals. Moderate-to-severe inflammatory acne is treated with prescription topicals, and if these are not effective oral antibiotics might also be prescribed. People with severe nodular or cystic acne need to see a dermatologist and may be prescribed isotretinoin. This prescription markedly reduces the size of oil glands, but comes with serious side effects. Source: [NIH](http://www.niams.nih.gov/health_info/acne/)
