Approximately 80 percent of people between the ages of 11 and 30 suffer from acne, states the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS). Also, in the United States another 14 million people, between the ages of 30 and 60, suffer from rosacea. Understanding the various causes of acne and rosacea may help prevent future outbreaks in those suffering from these conditions.

Causes Of Acne

The Mayo Clinic states that the three main factors contributing to the development of acne include the overproduction of oil, the irregular shedding of dead skin cells, and the build up of bacteria. The overproduction of oil may be influenced by heredity, certain medications, bacteria or hormones. The NIAMS advises that adolescent girls and adult women may see an increase in acne 2 to 7 days before they menstruate. Extra oil may build up on the skin from certain skin products or from working around oils or grease. Excess pressure from sports equipment, tight collars or backpacks may also increase the severity of acne. Finally, acne may flare from environmental irritants (pollution and high humidity), squeezing or picking blemishes, hard scrubbing of the skin and excessive stress.

Causes Of Rosacea

The exact cause of rosacea remains unknown. The Mayo Clinic advises that a combination of heredity and environmental factors play a role in the development of rosacea and in its severity. Any activity that increases the blood flow to the surface of the skin may aggravate or worsen rosacea. According to the NIAMS, rosacea may a condition were the blood vessels dilate too easily, causing flushing and redness. Some of the factors affecting rosacea include heat, hot baths, strenuous exercise, wind, sunlight, very cold temperatures, hot or spicy foods or drinks, menopause, alcohol consumption, long-term use of topical steroids on the face and stress. The American Orthopedic College of Dermatology (AOCD) states that other common factors of rosacea include harsh soaps, exfoliating creams, medications that dilate the blood vessels, certain foods and chronic coughing. The National Rosacea Society advises that people with rosacea keep a diary of things that trigger their outbreaks.


According to the AOCD, another term for rosacea is acne rosacea. This skin disorder causes redness and pimples on the nose, forehead, cheekbones, and chin. While rosacea often resembles simple acne or adult acne, blackheads are seldom present. The causes of both rosacea and acne vary from one person to the next. A person who keeps track of her personal triggers for acne or rosacea, and does her best to avoid them, will be less effected by the condition.
