ever had an important event coming up, andbaam – huge zit in the middle of your forehead. ugh. hello cutis wearers, lissette here for dnews.acne vulgaris, also known as those annoying painful oozing red bumps or dark dots on yourskin, is something that affects almost all of us – especially during our teenage years.but what causes acne in the first place and why is it so difficult to treat? well, there are a ton of different ideas outthere – ranging from hormones to diet, to our genetics and even psychological reasons-like stress. which might explain that pimple before prom. although, little is known forcertain; some of these hypotheses, however,
do have more support than others. one surprisingnew study, published in may 2016 in the journal cell,blames your dna. scientists from yale took blood samples of three individuals sufferingfrom acne and discovered that all three samples of dna had mutations within the genenek9. this gene is responsible for hair follicle production on your skin. but, this mutationcauses a defect in the follicle which makes it produce large blackheads and acne insteadof normal hair. according to the lead researcher, dr. keith a. choate â€œall acne is dependentupon hair follicles,â€. so it makes sense to look at the genes responsiblefor hair production in our search for what causes acne. itâ€™s an exciting new path ofstudy. now the yale researchers looked at
one specific type of acne, called nevus comedonicus,but a meta review of many studies on different types of acne states seem to suggest thatyour mom and dad might be the problem. the review found that acneâ€™s heritability isactually around 80% for first degree relatives. so if youâ€™re parents had acne, chances areyou will too. another potential culprit might be naturallyoccurring bacteria in your body. while research is unclear, there is some evidence that bacterialorganisms like propionibacterium, a common bacteria foundon your skin might cause acne. some evidence that lends credence to this argument is thatresearchers have found that antibiotics can sometimes help with decreasing acne. but,theyâ€™re not really sure if itâ€™s the antibioticâ€™s
anti-inflammatory or anti-bacterial propertiesthat are doing the job. so it could be that inflammation is the problem and not bacteria,but again no one knows for sure. a common idea is that diet can wreak havocon your skin. many people swear that certain foodslike chocolate or butter cause them to break out; and hey every body is different, thismay be the case for you. but when it comes to scientific experiments, the evidence toback this up is lacking. a meta review conducted by scientists at the university of nottinghamâ€™scentre of evidence based dermatology looked at many studies that considered the relationshipbetween diet and acne. altogether they found only one study that showed what you eat makesa difference. a diet low in glucose seems
to be associated with better skin, but thisis definitely not enough to make conclusions. so treat yourself 🙂 this lack of research and understanding aswell as the fact that there are different types of acne with potentially different causesbehind it, makes it so tricky to treat. there is likely never gonna be one silver bulletthat cures it all. luckily, for most of us, acne goes away after our 30s. on top of this,most acne, as uncomfortable as it may be, is largely benign. so, while it might ruinyour day, itâ€™s probably not going to last forever. guys, we are thrilled to launch an all-newseeker.com, which is home to all of dnewsâ€™
