What really causes pimples and acne?

<div> <div class="copy"> <h2>What causes acne?</h2> <p>It afflicts millions of people each year, according to the <a rel="noreferrer noopener" href="https://www.aad.org/" target="_blank">American Academy of Dermatology</a>. But is it true that hormones and carbohydrate-filled foods really cause the biggest symptom of acne – pimples?</p> <p>Hair follicles produce an oil known as sebum, which limits the amount of water entering our skin.</p> <p>But when too much sebum is produced, it feeds a <a rel="noreferrer noopener" href="https://cosmosmagazine.com/science/biology/charting-the-molecular-diversity-on-human-skin/" target="_blank">bacterium living in your skin</a> known as Propionibacterium acnes, causing your immune system to flush blood and white blood cells to the area.</p> <p>And if the follicle clogs up, a pimple forms.</p> <p>It’s also thought carb-rich foods contribute to acne, as they increase a compound in your body known as insulin-like growth factor 1, which turns up sebum production.</p> <p>Androgens – a family of hormones including testosterone – also boost your body’s sebum production, leading to more pimples.</p> <p>Puberty and menstruation both cause significant hormonal changes, making teenagers prime candidates for acne and causing many women to break out around the time of their period.</p> <div class="embed-container"><iframe class="note-video-clip responsive-embed" src="//www.youtube.com/embed/KrMbwDil1hc" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div> <p>Check out the American Chemical Society’s video above for more, as well as tips on how to minimise and control acne.</p> <em>Image credits: Getty Images</em></div> <div id="contributors"> <p><em>This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/science/biology/what-causes-acne-and-pimples/" target="_blank">cosmosmagazine.com</a> and was written by Jana Howden. </em></p> </div> </div>

17 daily habits of people who never get acne

<p><strong>Clean skin isn't easy</strong></p> <p><span>Some people never have to deal with the difficulties of a spotty complexion; others just take extra steps to manage their acne, something that is possible with diligence. </span></p> <p><span>Here are the secrets of the blemish-free.</span></p> <p><strong>They never skip a face-wash</strong></p> <p><span>Wondering how to prevent acne? You might start by considering your choice of skin cleanser and how often you use it, says assistant professor of dermatology, Dr Joshua Zeicher.  </span></p> <p><span>“While having acne does not mean that you are dirty, washing your face has been shown in studies to improve the appearance of acne,” he says. “Using a gentle skin cleanser that effectively removes dirt, oil and makeup from the skin can help maintain a healthy skin barrier.” </span></p> <p><span>The key is to actually wash your face. Every. Single. Night. Skipping your daily face wash regimen, he adds, may lead to breakouts as dirt, oil and makeup can block your pores.</span></p> <p><strong>They clean their smartphones</strong></p> <p><span>Don’t freak out, but your phone screen is way dirtier than you think. “Studies have shown that your mobile phone is dirtier than a public toilet,” Dr Zeichner says. </span></p> <p><span>“If you are not cleaning it regularly with an alcohol swab and it rubs against your face, you may be transferring that dirt to the skin, which combined with friction, may promote breakouts,” he says. </span></p> <p><span>Dermatologist Dr Ted Lain adds, “Plastering a phone to your cheek for minutes on end could lead to not only occlusion of the pores, but also infection and then acne.”</span></p> <p><strong>They never touch their face</strong></p> <p><span>Frequent face-touching can cause breakouts, Dr Zeichner says. </span></p> <p><span>“Leaning on your palm during the day can create friction against the skin, create inflammation and actually transfer dirt and oil that may get trapped in your pores,” he says. The solution? Don’t do it.</span></p> <p><strong>They change their pillowcases frequently</strong></p> <p><span>Even if you are steadfast in your nighttime face washing ritual, not changing your pillowcase on a regular basis can result in breakouts. </span></p> <p><span>When you don’t refresh your pillowcase at least once per week, dirt and oil build-up, and when you put your face into the pillow at night, these blemish-causing substances can clog your pores, explains dermatologist, Dr Betty Rajan. </span></p> <p><span>The type of pillowcase doesn’t matter much when it comes to the transfer of dirt and oil, but one of the ways that dermatologists wake up with younger-looking skin is by sleeping on soft, less abrasive pillowcases.</span></p> <p><strong>They eat like Greeks</strong></p> <p><span>Add better skin to the list of benefits associated with a traditional Mediterranean diet, says Dr Lain. This healthy way of eating is rich in vegetables, olive oil, whole grains, plus small amounts of lean animal protein and of course, some red wine. </span></p> <p><span>“It is clear that the typical [Western] diet, which is high in refined flours and saturated fats, bodes poorly for a good complexion.” </span></p> <p><span>This may be one of the reasons that reservatrol, the beneficial compound in red wine, is popping up in skin-care products.</span></p> <p><strong>They try to never pick, pop or squeeze</strong></p> <p><span>Picking or scratching at your acne leads to open wounds, prolonged healing, and sometimes scarring, Dr Lain says.  </span></p> <p><span>“In addition, we all have bacteria on our hands, therefore you transfer bacteria to your face and lead to more infection.”</span></p> <p><strong>They try to watch their weight</strong></p> <p><span>Being overweight or obese is a risk factor for a host of illnesses including heart disease and some forms of cancer, and there is a link between acne severity and obesity too. </span></p> <p><span>“To minimise acne risk, keep your body mass index in the ideal range by exercising, eating correctly, and minimising sugar intake,” Dr Lain says.</span></p> <p><strong>They mind their microbiome</strong></p> <p><span>The microbiome is the collection of normal bacteria, fungi and viruses that live on the skin and in our gut. A growing body of research suggests that a balanced microbiome is super important for skin health. </span></p> <p><span>“There is no one skin-care product or supplement that will absolutely protect or repair the microbiome,” Dr Lain says, but some studies have shown that people with acne tend to have an imbalance of good to bad gut bacteria and that certain probiotics (such as Lactobacillus paracasei) can improve barrier function and make skin less reactive.</span></p> <p><strong>They try to wash their hair regularly</strong></p> <p><span>All of the natural oils produced by our scalps to protect the hair can also clog pores on the face and lead to acne, Dr Lain says. </span></p> <p><span>“Washing hair helps remove the excess oil on the scalp and hair, which minimises the oil at the hairline and forehead.” But avoid heavy, oily hair-care products during styling, Dr Zeichner warns. </span></p> <p><span>Touching the skin on the forehead may block pores and lead to pimples.</span></p> <p><strong>They may avoid some types of milk</strong></p> <p>People who don’t drink cow’s milk may be less likely to get acne than those who do, says dermatologist, Dr Joel Schlessinger.</p> <p>A 2016 study of 225 teens aged 14 to 19 that was published in the <em>Journal of the American Academy of Dermatology</em> found that people who drank more low-fat or skim milk had more acne than people who did not drink as much. (The study included teens with moderate acne or no acne.)</p> <p>However, there was no link between acne and the consumption of dairy (in general) or full-fat milk. The authors note that the research on the topic has been mixed, and the study can’t determine if one factor caused the other.</p> <p>(It’s possible that skim milk is devoid of the good-for-your-skin fatty acids found in whole milk.) Some think it has to do with the high ratio of sugar found in skim milk. If you like it, you might consider trying almond milk.</p> <p>“Almond milk contains all of the great vitamins and calcium we need, but without any of the hormones,” Dr Schlesinger says.</p> <p><strong>They pass on the pasta</strong></p> <p><span>There may be less white bread, white pasta, white rice, potato chips, or other high glycaemic index (GI)-scoring carbs on the menu for the blemish-free. Instead, they may be more likely to eat foods that rank low on this index, such as multi-grain bread, peanuts, vegetables and beans. </span></p> <p><span>Emerging data suggest that high glycaemic index diets may be associated with acne, according to the latest guidelines from the American Academy of Dermatology. </span></p> <p><span>Exactly how a diet that is high on the GI index can cause or contribute to acne is not fully understood, but low GI foods keep blood sugar levels stable while high GI foods may cause a blood sugar spike that can lead to inflammation and oil production, which plays a role in acne. </span></p> <p><span>What’s more, eating lots of high GI foods can also increase hormones which in turn dial up the activity of oil glands in the skin, causing acne.</span></p> <p><span><strong>They was their hands after working out</strong><br /></span><span></span></p> <p><span>Sure, working out on a regular basis helps us stay fit and healthy, but if we don’t exercise caution with hand hygiene, we may break out – or worse, because gym equipment can be full of bacteria. </span></p> <p><span>“Working out in a gym is potentially very dirty and can cause something that looks just like acne, but is actually a staph infection,” says Dr Schlessinger. </span></p> <p><span>“The best thing to do is to avoid touching your face while playing sports or working out. If you must, bring a towel or use the back of your hand or sleeve.”</span></p> <p><strong>They try not to share makeup</strong></p> <p><span>No matter how jealous you are of your BFF’s new bronzer or a colleague’s mascara, don’t borrow it.</span></p> <p><span> “Sharing makeup is sharing bacteria with a friend,” says Dr Schlessinger. Whatever you do, don’t try on makeup in a store unless you test it on your arm or the back of your hand.</span></p> <p><strong>They don't smoke</strong></p> <p><span>In case you needed one more reason to kick the habit, smoking may also cause acne, according to research out of the San Gallicano Dermatological Institute in Rome, Italy. </span></p> <p><span>Smokers may be more likely to develop non-inflammatory acne.</span></p> <p><strong>They don't stop fighting the fight</strong></p> <p>It can be oh-so-tempting to skip the skin-clearing products in our skin-care regimen, but this is a mistake, says clinical assistant professor of plastic surgery, Dr Mark H. Schwartz.</p> <p>“It is natural to want to stop using acne-fighting products when your skin is clear, but acne is chronic and requires long-term care to keep it under control – even when you are travelling.”  </p> <p>Make sure you take your acne medications as directed for as long as directed.</p> <p><strong>They stay out of the sun</strong></p> <p><span>Just how bad is tanning? Do you really need to ask? Skin cancer risk aside, it may also worsen acne. Despite a popular misconception, tanning doesn’t make acne better, warns Dr Lain. </span></p> <p><span>UV rays actually dry out and damage your skin. Certain acne medications also increase sun sensitivity, making a burn more likely. </span></p> <p><span>Always wear broad spectrum sunscreen with a sun protection factor of 30 or higher and reapply it frequently.</span></p> <p><strong>They protect their skin from pollution</strong></p> <p><span>Some research suggests that smog, chemicals and toxins in the air can clog your pores and cause acne, points out Dr Schlessinger. </span></p> <p><span>If you are a city dweller, there’s not much you can do to avoid pollution, but sunscreen will create a barrier between your skin and the toxins, and antioxidant serums can help fight damaging free radicals in air pollution.</span></p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a rel="noopener" href="https://www.readersdigest.co.nz/healthsmart/beauty/17-daily-habits-of-people-who-never-get-acne?pages=1" target="_blank">Reader's Digest</a>.</em></p>

Mum’s unconventional hack divides opinion

<p><span style="font-weight: 400;">A new mum’s unconventional solution for her baby’s acne has divided the internet, due to the presence of one unconventional ingredient.</span></p> <p><span style="font-weight: 400;">Linh Ta took to TikTok to share her hack, filming herself placing a face mask sheet in a bowl of liquid before applying it to her son Levi’s face.</span></p> <p><span style="font-weight: 400;">In the clip, Linh Ta reveals the bowl contains liquid gold, telling followers that she uses breast milk to soothe her son’s skin.</span></p> <p><span style="font-weight: 400;">“When your baby has acne so you make a breast milk mask for him,” she captioned the clip.</span></p> <p><span style="font-weight: 400;">Baby Levi can be seen sleeping peacefully as she puts the mask on him, which she leaves on to help his skin absorb the milk.</span></p> <p><span style="font-weight: 400;">In the comments, Linh Ta explained she made the mask “purely out of boredom” and “just to have a little fun”.</span></p> <p><span style="font-weight: 400;">“I’m a first mum so I’m learning things as I go,” she said.</span></p> <p><span style="font-weight: 400;">The video, which has been viewed more than four million times so far, has divided other users on the platform. Some were fans, while others were less enthusiastic.</span></p> <p><span style="font-weight: 400;">“Sooo cute! But the acne will pass. It’s just your hormones leaving their body. It’s not like our acne,” one fan explained.</span></p> <p><span style="font-weight: 400;">“Um my heart is screaming, this is too cute. Not me going to cut up a dry wipe and do this on my nine-week-old,” another agreed.</span></p> <p><span style="font-weight: 400;">“This just rubs me the wrong way,” one user argued.</span></p> <p><span style="font-weight: 400;">“Mini serial killer mask,” another added.</span></p> <p><span style="font-weight: 400;">In a follow-up video, Linh Ta shows Levi’s clear face in response to a fan asking for before and after photos.</span></p> <p><span style="font-weight: 400;"><img style="width: 277.1285475792988px; height:500px;" src="https://oversixtydev.blob.core.windows.net/media/7842560/placeholder_8729e81ef4f4d57_0.png" alt="" data-udi="umb://media/8df990dcc851409d956f9a785ee96c14" /></span></p> <p><span style="font-weight: 400;">“They were red and raised before and now the redness has subsided,” she said in the update.</span></p> <p><span style="font-weight: 400;">Though there is </span><a rel="noopener" href="https://www.healthline.com/health/baby/baby-acne-breast-milk#breast-milk" target="_blank"><span style="font-weight: 400;">no scientific evidence</span></a><span style="font-weight: 400;"> supporting the use of breast milk to treat baby acne, some people swear by the remedy.</span></p> <p><span style="font-weight: 400;">Since breast milk has antimicrobial properties, the breast milk may help reduce or destroy bacteria and other impurities that block the baby’s pores and cause acne.</span></p> <p><span style="font-weight: 400;">However, research from the </span><a rel="noopener" href="https://scholarworks.waldenu.edu/cgi/viewcontent.cgi?article=1108&amp;context=sn_pubs" target="_blank"><span style="font-weight: 400;">International Journal of Childbirth</span></a><span style="font-weight: 400;"> recommends simply keeping the baby’s skin clean with soap and water and avoiding oils or lotions that could worsen the acne.</span></p> <p><em><span style="font-weight: 400;">Images: Tiktok</span></em></p>
