Cause of pimple

She’s only a few feet away.The closer he gets, the more nervous he becomes,the budding zit on his nose growing bigger and bigger until it practically eclipses his face.She looks at him hovering nearby, sees the massive zit, and giggles.He slumps away, feeling sick.
Stress can sure make a mess, and it happens to both teens and adults.
But how does it happen?
Let’s rewind to before the zit, to before Justin even sees his crush.
Already late for school, Justin got to class just in time to hear the teacher say “pop quiz.”
He hadn’t done his homework the night before, and felt more unprepared
than the ambushed World War II soldiers he was supposed to write about.
A sudden rush of panic swept over his body, leaving him with sweaty palms,a foggy mind and a racing heart.
He stumbled out of class in a daze, and ran straight into his all-time crush, spiking up his stress.Stress is a general biological response to a potential danger.In primitive caveman terms, stress can make you fight for your life,
or run for your life, if, for example, you’re confronted by a hungry saber-tooth tiger.Special chemicals called stress hormones run through your body,
giving you more oxygen and power to run away from danger
or to face it and fight for your life,hence the term “fight or flight.”But when you don’t fight, or take flight, you face the plight.When we’re taking final exams, sitting in traffic or pondering pollution,
we internalize stress.It all begins in the brain.The hypothalamus, the master controller of your hormones,releases something called corticotropin-releasing hormone.This triggers the pituitary gland,a pea-sized gland found at the base of the brain,to release adrenocorticotropic hormone
which then stimulates the adrenal gland sitting on top of the kidneys
to release cortisol, the major stress hormone.
These natural chemicals are a great help when you need to run away quickly,
or do superhuman feats of courage,
but when you’re simply sitting, these stress hormones collect in the body and affect your overall health.
Stress hormones increase inflammation in the body,
suppress the immune system,which makes you more susceptible to infection by acne-causing bacteria,
and can even increase oil production in the skin.
And this is the perfect storm for forming a pimple.
Cortisol is a major stress hormone involved in making skin cells
churn out oily lipids from special glands called sebaceous glands.
But when there’s too much of these oily lipids,
called sebum, they can plug up the swollen, inflamed pores
and trap the pesky, acne-causing bacteria inside,
where they set up house and thrive.
Add a dash of inflammatory neuropeptides released by the nervous system when you’re –well, nervous — and angry zits follow.
To make matters worse, Justin is a boy, meaning he’s got more testosterone than girls.Testosterone is another hormone that increases oil production in the skin.
So, his already oily skin, together with a boost in oil and inflammation from stress,is the perfect environment for bacteriato swell, swell, swell up into a major zit.So what could’ve Justin done to avoid the big pimple?
Stressful situations are unavoidable.But we can try to change our responses so that we’re not so stressed in the end.And had he been confident in approaching her,she might not have noticed the pimple, or he might not have had one.
