Do you suffer from adult acne? Chances are, if you suffered from acne when you were a teen, you are fairly likely to have some acne at some point in your adult life. However, if you didn’t have much acne as a teen and you have it now as an adult, you’re probably wondering why you started having it. There are many adult acne causes, and no two people are alike in this regard, but there are some common causes for adult acne.1. Hormones: If you are a female going through her menstruation cycle or a pregnancy, you can expect to get acne.2. Stress: My dermatologist told me part of my adult acne was caused by stress. Then she proceeded to tell me to try to cut stress out of my life. I don’t know about you, but if you can just “cut out stress” in your life, we wouldn’t have it to begin with! This is obviously not a very viable option, but it is nonetheless an adult acne cause.3. Beauty products: Many adults, especially women, are into using bathing and beauty products containing fragrances or other harsh chemicals that irritate the skin. Ladies, if you’re not already doing so, switch to a makeup that is noncomedogenic, which means it won’t clog your pores; Clinique or mineral makeup are good alternatives.For both sexes, switch to a no-fragrance-added shampoo. I use Head and Shoulders 2-in-1 shampoo and conditioner with pyrithione zinc. The zinc helps kill bacteria in your skin and doesn’t contain any harsh fragrances or ingredients. It also keeps away scalp acne, which is especially irritating, at least to me.4. Your diet: It’s not that you’re eating too much chocolate. But one of the only ways you’re going to control your adult acne is with an acne cleanse diet. You can use foods and things you can find at the grocery store without ever having to visit the dermatologist.
