When I saw an acquaintance go to get her eyebrows “micropigmented,” I raised a brow (sorry, not sorry). This is a sub-category of microblading that essentially requires making the equivalent of a paper cut in the skin to deposit semipermanent color for each hair, micropigmentation utilizes a single-needle tattooing machine to create fine, hairlike strokes. The result is softer and more natural than more traditional microblading marks and lasts for about a year—exactly what I was looking for....

But if you’re unable to get up the gumption to go full brow tattoo, you’re not alone. (Permanence can add pressure, and who knows what the new eyebrow trend will look like once a new decade rolls around?). Good news: Eyebrow tinting is a happy middle ground, perfect for those looking to enhance their arches for a time, no needles necessary. Here’s everything you need to know about the brow dye job....

The four main heavy metals that can cause health issues are mercury, lead, arsenic, and cadmium. The U.S. Food & Drug Administration1 monitors levels of these “big four” heavy metals in food and drinking water, but some sources inevitably fall through the cracks. (Take the high levels of lead in the water in Flint, Michigan, for example.) Here are four sources of heavy metals to look out for and avoid consuming in high doses....

In another study, scientists found that burning frankincense resin (such as with incense) may have positive psychoactive effects5. Researchers investigated the impact of incensole acetate, purified from frankincense, on mice and found that it reduced their anxiety and caused antidepressive-like activity. Although frankincense shouldn’t replace a rescue inhaler or other prescribed asthma treatments, asthma sufferers may find that frankincense can help stave off bronchospasms, also known as an asthma attack. During an attack, mast cells release leukotrienes6, which then cause airways to constrict, making it hard to breathe....

That said, collagen decline is a natural part of life. It will happen to all of us, and there’s no use in denying that fact. In fact, at some point in your late 20s, your collagen will start to decline at a rate of about 1% every year for every year thereafter1. This is why most folks start noticing signs of premature aging in their 30s—and why many people usually start focusing on preventive aging around this time....

But, as with most aspects of our well-being, there’s a lot more to understand than what lies on the surface. So just how much do you have to run to lose weight? Let’s break it down. So if you wanted to lose 5 pounds, you would need to run 180 miles if you didn’t change anything else about your lifestyle! This is, of course, unrealistic for the majority of us, which is why it’s important to factor nutrition into this equation....

Here’s what research has revealed about the cause of sleep inertia and how to keep it at bay. Sleep researchers aren’t totally sure what causes or intensifies sleep inertia, but they suspect it has something to do with the body’s circadian rhythm, also known as our internal clock. In one small study on emergency workers2 who need to be “on” as soon as they wake up, the effect of sleep inertia was tested throughout the night....
