Say you broke out with zits today. What did you have for dinner last night? Did you also go out for beer with friends?
Certain food and beverage cause havoc for certain people. The reason is it disrupts the pH balance in their guts, often leading to too much acidity. There's a strong correlation between our gut and our face. The best way to counteract this problem is to eat yogurt and probiotic.

Another culprit is our hormones. Any time you disrupt the hormonal balance, it will show up on your face. For example, adult acne is mainly a manifestation of hormonal imbalance. There are many things that can disrupt our hormones. Sickness is a major reason, but there are many minor reason as well, such as too much sexual activities.

Anyway, the best remedy for you is to calm the acne down as possible. Start by taking 2 pills of aspirin or advil to bring down the inflammation. In the evening, apply a thin coat of VapoRub or arthritis cream to the face. The goal is to reduce inflammation. By doing this, acne will heal much faster. Nevertheless, continue taking a lower dose aspirin (eg. 81 mg, aspirin for children) as a preventive measure.
