* Dermatologist Dr Vishal Maden called part of the face a 'danger triangle'
* Spans from bridge of nose down to corners of mouth and top lip
* Blood vessels in this zone drain back to the head and connect to the brain
* Infections could lead to vision loss, permanent paralysis or even death
It might be tempting to squeeze a pesky spot on your face.
But according to a Salford dermatologist it's a bad habit that can do more than just scar you.
In rare cases, it could actually kill you, says Dr Vishal Maden.
It's all down to an area on the face known as The Danger Triangle, which is found across parts of the eyes, the bridge of the nose, the corners of the mouth and the upper lip.
He told BBC Radio 5 Live Breakfast blood vessels in this zone drain back to your head and connect directly to your brain.
Infections there could lead to vision loss, permanent paralysis, or even - theoretically - death, he said.
'Now, if there is an infection in this area that is not treated properly or quickly, this infection can cause thrombosis or clot of blood, or an infection or abscess in the brain, or even meningitis,' he told the show.
'All of this can be potentially devastating.'
Dr Madan said the risk of the most serious effects happening is extremely rare, and the risk of scarring is the main reason to resist the 'human nature' that makes it so tempting to squeeze those spots.
'I see patients on a daily basis who’ve got acne, pimples, and I see the scarring and the first thing I ask is: "do you touch your spots, or squeeze them?" And invariably most people do.'
WHY DO WE GET PIMPLES AND CAN WE AVOID THEM?
To squeeze or not to squeeze?
I'll admit that I'm no skin saint.
I have stood in front of the mirror on a number of occasions as a teenager with a big pimple staring right back at me.
Squeezing a pimple can make it worse as it can result in lood vessels in this zone drain back to your head and connect directly to your brain
And yes, despite being advised not to, I have squeezed, picked and popped.
But is this really a crime against the skin? The answer is yes.
Squeezing and trying to pop pimples is definitely not the best solution and can actually make your skin worse.
HOW PIMPLES FORM
Acne is one of the most common inflammatory skin conditions in adolescents. More than 80 per cent of teenagers battle with pimples.
It can also occur later in life for a number of reasons, including an imbalance of hormones called androgens.
At the moment, we need more research to fully understand the causes of acne.
Oil glands (sebaceous glands), located in the skin at the base of the hair follicle, excrete oil (sebum) to lubricate the surface of the skin and hair.
All parts of the body contain sebaceous glands, except the palms and soles of the feet.
Oil glands (sebaceous glands), located in the skin at the base of the hair follicle, excrete oil (sebum) to lubricate the surface of the skin and hair which can become blocked and infected
Acne was previously thought to come from lack of normal shedding of the skin cells that line the sebaceous (oil gland) follicle.
This was thought to lead to thickened skin and the formation of small comedones (black and white heads).
But there has been a shift in this thinking in recent years.
WHY YOU SHOULDN'T SQUEEZE
A pimple is like a little bag under the skin that contains oil, bacteria and inflammation.
Squeezing it can result in these contents being pushed into surrounding skin, making the problem worse.
It can also lead to infection and temporary darkening of the skin in that area.
On top of this, the inflammation can become so bad that scarring is left behind when the pimple finally settles down.
And scarring (unlike the pimple) can be permanent.
If you resist the urge to squeeze, pimples will usually resolve over a week or so without scarring.
The 'white' contents will also settle down or spontaneously pop when ready.
If large pimples require urgent treatment, a dermatologist can get rid of the contents of a pimple safely.
They may also give it an injection that decreases inflammation and the pimple in a day or so.
If pimples are something you battle with even on a monthly basis, it is advisable to see a dermatologist to find out what can be done to control the flares.
HOW TO PREVENT PIMPLES FROM POPPING UP
If you want to avoid pimples, here are some ways you can have healthier and clearer skin.
Eat a healthy, well-balanced diet low in sugar.
This includes nuts, legumes, fish, red meat, fruits and vegetables. A number of well-conducted trials support the for patients who have acne.
Some studies suggest a higher risk of acne with frequent milk consumption, but more research is needed before dietary recommendations can be made.
It’s advisable to keep a diary to see if any of these foods directly aggravate acne and avoid them if this is the case.
Avoid excessive scrubbing, cleansing and exfoliating.
Acne doesn’t happen due to accumulation of dirt and grime on the skin and can’t simply be washed away.
Using many products can increase skin irritation and dryness and compound the problem.
Choose oil-free cleansers, moisturisers and sunscreen (these are usually labelled “non-comedogenic” on packaging).
Choose silicone-based hair products rather than greasy ones.
Greasy hair products can make more oil and grease accumulate on the skin, which will make acne worse.
And if you do get pimples, try to resist the urge to squeeze!
