its diet, stress, cleaniness&hygiene, your dna that you inherit from your parents, its where you work and your freggin hormones.
eating junk is going to kill us and make us look bad.
touching greasy french fries and then touching our faces is going to make pimples.
the stress of school , dating, parents, future plans, work, bills is going to take a toll on our bodies.
if our parents had bad acne, we can inherit that.
if you work around grease or dirt, its going to land on your face and cake up your pores.
if you arent cleaning your face right, its going to leave zits.
and raging hormones also cause zits.
most people get to their early to mid 20s and this stuff stops because their diets are better, the stress level is way down, puberty is over and they get jobs that are cleaner.
some people get horrible acne where others just get a few zits. its not fair to the people that get them on their backs either. now they have new treatments out that are costly but more effective than using clearisil or oxy.
the best thing that ever worked for me was to use rubbing alcohol. it would make me break out really bad, but then they would all go away for a while.
