Its been mentioned before that people may have a certain sensitivities to types of foods or products in the foods that they eat and can cause adult acne skin reactions. However its far more likely that an external cause may be aggravating or partially responsible for the acne.

The skin is the bodys largest organ and its on the outside of the body so its exposed to a variety of external factors which can cause irritation, infections, and even acne. Some people have more sensitive skin than others. You may be washing your face regularly with an acne cleanser but this may be too strong. Many people complain that the traditional cleansers with salicylic acid and benzoyl peroxide are too strong, leading to redness and dry skin.

In this case you can go off of the over the counter cleanser that is bothering you and irritating your acne skin or you can look for a different cleanser with different formula. In the case of cleansers the formula is the most important thing for your skin. If you do have irritation look for a cleanser with less of the active medication, for example .5% benzoyl peroxide instead of the 1 or 2%, and try to get a cleanser that doesnt have alcohol in it. Alcohol is very drying.

When rinsing off your face you normally use tap water, but this tap water may contain chemicals or minerals that are too harsh for your skin leaving it with red splotches of color and irritating the all ready sensitive skin with acne on it. You may wish to test your water to make sure it isnt too hard or soft and test the pH level to make sure it isnt too alkaline or base for your skin. You can easily correct the water by picking up a simple water purification system that attaches to your faucets.

Other typical acne skin irritants can be pollution, excess sunshine, pore clogging skin creams, lotions and make ups and greasy work environments.
