Does unhealthy food cause or inflame adult acne? resulting in pimples or anything. my dermatologist says it seems play a huge factor?

Yes, in some people: Some people are especially reactive to dairy products -- there could be others. This is not the same as an acute allergic response, but food intolerance can show up in many kinds of symptoms, including skin manifestations. Ask your dermatologist what suggestions s/he has for you in particular.

Acne: Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells.These factors can trigger or aggravate an existing case of acne, hormones, medications, and a diet with a lot of dairy and carbohydrate-rich foods.You can also prevent new acne breakouts with self-care measures by washing your skin with a gentle cleanser and avoiding touching or picking acne.
