So, what is acne exactly? Acne is a common skin condition that is most common during adolescence. While adult acne does occur, this condition is more popular with the younger crowd — affecting more than 85% of all teenagers.

There are several different types of acne, including acne vulgaris, acne rosacea, acne conglobata, acne fulminans, pyoderma faciale, and gram-negative folliculitis. Cases range from mild to extremely severe, and treatments differ case by case.
