This is still a debate among parents of today s teenagers and dermatologists. Drugs and alcohol are also culprits in causing acne. When the body cleans itself, it sends drugs and alcohol out through the skin, through sweat. The skin pores become clogged and oils and dirt become trapped. They then become infected, which is what we call pimples, whiteheads and blackheads.
Stress is another culprit of flare-ups.
Stress brings upon different hormone levels. With hormone changes the body prompts the skin s oil glands to enlarge, secreting more oil. Which causes white heads, black heads and pimples. Oily or heavy make-up is another cause of acne. Vitamins are good for your body, But an excess of vitamins B1, B6 and B12 can cause acne flare-ups.
