What are the symptoms of acne?

Acne can occur anywhere on the body. However, acne most often appears in areas where there is a high concentration of sebaceous glands:

* face
* chest
* upper back
* shoulders
* neck
The following are the most common symptoms of acne. However, each person may experience symptoms differently:

* blackheads

* nodules (solid, raised bumps)
The symptoms of acne may resemble other dermatologic conditions. Consult a physician for diagnosis.
