When an eye cream stays flying off of Sephora shelves, you know it has to be good—though, to be fair, Biossance’s formula is technically more of a gel-like texture. Better yet, the brand uses naturally-derived ingredients, so sensitive skin types need not fret.

As of right now, the Biossance Squalene and Peptide Eye Gel is the top-seller in the retailer’s eye cream category, and last month at the Beauty Insider Appreciation event, the product sold out completely. Those who have tried out the formula can attest to its power, claiming that dark circles, puffiness, and wrinkles had practically disappeared in roughly three weeks.

Pick up a bottle for $54 if you can at sephora.com.

If you aren’t familiar with the squalane ingredient, it’s pretty comparable to the sebum your body naturally produces, and actually prevents your skin from losing any moisture. Biossance’s ingredient is derived from plant origins, and since it’s hydrogenated, it’s pretty lightweight and easy for your complexion to drink in.

Additionally, the peptide-rich gel promotes microcirculation, and once your blood is flowing, you look less tired and any traces of dark circles start to fade. The side of Swiss apple stem cell extract (say that five times fast) supports lymphatic drainage, resulting in a less-puffy appearance. Whoever said organic products aren’t as effective as the hard stuff has clearly never tried this eye gel.

If you’re still on the quest to find the perfect ‘90s nude, let us introduce you to a tube that was actually born in the decade we’re all so nostalgic for. While lipstick colors come and go with discontinuations and limited-edition lines, MAKE UP FOR EVER has kept one in stock since its creation in 1990, and its pinky-nude pigment will help you achieve all your favorite throwback, classic, and modern looks.

Rose Wood ($22; sephora.com), a nude tone with a satin finish and a comfortable wear, was created as part of the Artist Rouge Lipstick Collection 27 years ago and can still be found at your nearest Sephora.

And while the fact it has stuck around for so long speaks to its popularity with buyers, as it turns out, the brand created the tone to flatter everyone, and it was actually tested on 25 different skin tones!

In October of my junior year of high school, I was at the top of my cross-country game. I was running five to six days a week, knocking more and more time off my mile split, and gearing up for a big race that would finally prove I had what it took to hit varsity status. So when opportunities arose to run a few extra miles and push myself harder, I took them without a second thought.

Then came the day of the race. I’d been noticing some pain and throbbing in my shins for a few days, but assumed I just had shin splints—something I’d dealt with many times in the past. So before my event, I popped a couple of Ibuprofen and visualized myself totally dominating the race. Spoiler: That’s not what happened.

When the race started, I took off and headed to the front of the pack. I kept up my pace as I wove through the trail, adrenaline surging through my body. That is, until about mile 1, when my runner’s high was interrupted by an excruciating pain in my left shin.

I tried to ignore it, unwilling to give up just yet. But the pain only got worse, and soon I was limping. Girls passed me left and right, but I kept hobbling my way across the grassy path until I reached the finish line and collapsed.

Fast forward through two doctor’s visits, an X-ray, and a bone scan. The verdict was that I had seven small stress fractures in my left shin.

My case is certainly nothing out of the ordinary. In fact, ABPM-certified podiatrist Melissa Lockwood, DPM, says nearly one in five runners she sees is for a stress fracture. But why do young, healthy people end up with this injury? Here, she explains what causes stress fractures, and shares tips for preventing and treating them.

What is a stress fracture?

Stress fractures are characterized as “overuse injuries.” They occur when a bone experiences repeated, unusual force, says Dr. Lockwood, who’s based in Bloomington, Illinois: “For example, when runners increase their distance and speed—basically anything that changes the amount of pressure they’re putting on the body.” 

Dr. Lockwood typically sees these injuries happen in the metatarsals, which are the small bones right behind your toes, and the lower leg (as in my case). According to the American Academy of Orthopedic Surgeons, more than 50% occur in the lower leg.

While stress fractures are associated with running, “they can also be caused by regular force, if the bones are weakened by other problems, such as osteoporosis or another systematic problem like an eating disorder,” adds Dr. Lockwood. Research suggests women are more susceptible, possibly because they’re more prone to the above-mentioned conditions.

But really, stress fractures can affect anyone. Dr. Lockwood got one in her foot after walking around Disney World all day. (See her X-rays below.)
