Researchers have now identified and catalogued more species that reside on the human skin than has ever been possible, largely due to advances in bioinformatics and laboratory techniques. Some of these previously unknown species are the most abundant on human skin. The results appear in a new catalog, the Skin Microbial Genome Collection (SMGC), published today in Nature Microbiology.
Investigators at the National Human Genome Research Institute (NHGRI), European Bioinformatics Institute and the National Institute of Arthritis and Musculoskeletal and Skin Diseases participated in the collaborative study.
According to researchers, the new catalog is remarkable in its breadth, bringing to light an incredibly complex map of species that make up the skin microbiome. It also opens the door for scientists to figure out the root causes of various skin diseases.
“The organisms that make up the skin microbiome have an enormous impact on our health, and changes in the
Winter is upon us and it’s time to pay particular attention to our skin, specifically the outermost layer called the stratum corneum, aka the skin barrier. This thin brick-like cover consists of resilient skin cells called corneocytes that are tightly bound together by mortar-like lipids comprised of cholesterol, fatty acids, and ceramides. Crucially, the skin barrier not only protects us from external threats like environmental toxins and pathogens, but it also prevents dehydration.
“Defects of the skin barrier can lead to diseases such as eczema, dermatitis, asthma, and allergies,” warns Miami dermatologist Dr. Leslie Baumann. Moreover, “when skin barrier defects cause inflammation, the risk of inflammatory diseases such as diabetes and heart disease increases.” In other words, a robust skin barrier is vital to healthy skin and to good health in general.
There is substantial interest in the relationship between diet, nutrition, and dermatological conditions. New research assesses the existing research literature.
The review reports that much of the evidence supporting such relationships is based merely on associations or laboratory studies rather than on randomized controlled trials, which are the gold standard for medical research.
The study is the work of lead author Dr. Kabir Sardana and senior investigator Dr. Soumya Sachdeva, both of whom are affiliated with Atal
Cold weather brings about a lot of changes in how healthy we feel. From seasonal affective disorder (SAD) to the flu, it seems like the season can wreak havoc on our bodies.

A small, yet annoying, sign that winter is here are hangnails. Those ragged little pieces of skin you find around your nails can be annoying and become irritated if not taken care of properly.
Family medicine specialist Neha Vyas, MD, talks about how to remove a hangnail, what not to do and how to prevent hangnails in the first place.
Even though it’s called a hangnail, that little piece of skin isn’t part of the nail. Instead, it’s a torn piece of skin that hangs loose next
Skincare has become a buzzword, with beauty routines as prevalent as they are varied. The fact is that the skin is the body’s largest protective organ—and we should be caring for it accordingly. Skincare regimens are often undertaken to address cosmetic concerns like wrinkles and dark spots, with many brands playing directly to those symptoms. But the skincare industry is largely focused on—and marketing to—cosmetic results, rather than the loss of skin health which is responsible for them. The truth is that we can’t achieve lasting cosmetic outcomes without first addressing the skin’s health. Treating for symptoms alone, like dryness, leaves underlying causes unaddressed.
As an industry, skincare professionals and brands need to shift their focus to caring for skin health with ingredients that treat the cause—those that will result in better cosmetic outcomes while also restoring and preserving healthy skin. Here’s how we can do it.

Saffron. Maybe you’ve encountered the spice in a flavorful recipe you’ve made before or know it from the characteristic golden hue it gives different foods. But were you aware that saffron, derived from the dried stamens from the Crocus sativus flower, can actually be beneficial as a topical on your skin — and in more ways than one at that? “As a skincare ingredient, its benefits are its antioxidant and anti-inflammatory properties,” says Hadley King, MD, a board-certified dermatologist based in NYC. “Saffron is rich in carotenoids that may play a part in damage repair, helping the skin recover from daily oxidative stress. Saffron may also be able to increase cell turnover and help wounds heal faster.”
According to Shivangi Tripathi, owner of Mata Ayurveda, a holistic haircare and beauty brand, saffron’s been used
When I was on the junior varsity basketball team in high school, I wasn’t surprised when I developed a case of itchy, flaky athlete’s foot. After all, I was an “athlete,” so I assumed it was a sign of dedication and hard work.
I was shocked when my mother told me the truth: it was due to poor foot hygiene, not my dribbling skills.
Fast-forward almost four decades, and I’m much more diligent about skin care. Still, some skin issues plague me at times, like they do many men. Here is a look at two common problems and solutions.
Symptoms of dry skin include scaly patches (with or without redness), itching, and overall dryness. You can get dry skin year-round — from the heavy heat of summer to the bitter cold of winter. Sun exposure damages skin, leaving it thinner and less likely to hold in moisture over

Skin health is important because it performs many essential tasks for overall health. As the largest organ of the body, skin is a protectant from viruses, infection, and environmental threats. It regulates temperature and fluids.

Human skin is a multi-layered organ made up of tissues designed to protect underlying body parts such as bones and muscles. These tissues serve as a first line of defense by preventing pathogenic organisms and foreign substances from invading the human body. Beyond its protective functions, human skin also serves as an ecosystem for billions of microorganisms that colonize each fold, crease and niche from head to toe. In this article, we describe what the skin microbiome is, which microorganisms are part of the skin microbiome and how we’ve come to understand the various relationships between the human skin and its microbial residents through advanced genomics.
The skin microbiome1 is the collection of all microbiota and physical components that co-exist on human skin. While human skin is typically cool, dry and weakly acidic, there are distinct habitats including hair follicles, glands and skin of
