For our debut episode, we're setting the record straight on one of the most polarizing ingredients out there: cannabidiol, also known as CBD.

Ever pick up a jar of moisturizer, slather it over every inch of your face, then look at the ingredients list and realize...you have absolutely no idea what's actually inside that jar? Or, if it’s going to do anything at all for your skin? Allure’s senior beauty editor Dianna Mazzone hosts The Inside Story, a new miniseries from the producers of Allure’s The Science of Beauty podcast that cuts through marketing language and glittering claims to dissect the why, how, and what’s-in-it-for-me of some of the buzziest ingredients in beauty.

Do you hear a humming noise? You should, because running a humidifier is just one of the many ways you can help keep your skin happy and hydrated all winter long. Of course, there are tons of topical options too, but it's not as simple as slathering on the thickest cream you can find and saying a prayer. That's why Michelle and Jenny tapped Christine Lee, a senior research and development manager with AHC (Korea's #1 skin-care brand), and dermatologist Claire Chang to share why hydration is the key to "chok chok" skin (don't worry, we'll explain), and the best ingredients to achieve it.

Whether you’re assembling a rainbow cake or putting together a skin-care routine, proper layering is essential. And the multistep regimens that have become synonymous with K-beauty (we're talking 10, 12, and even 17 steps) have turned the way we apply serum, moisturizer, and oil into an art form. To master it, Michelle and Jenny called upon dermatologist Marie Jhin to share some hard-and-fast rules for layering and to spell out exactly how — and when — to apply your skin-care products for maximum benefit.

What's better than dedicating one episode of The Science of Beauty to all things K-beauty? Well, dedicating three of 'em, that's what! For the next several weeks, hosts Michelle Lee, editor in chief, and Jenny Bailly, executive beauty director, are taking a deep dive into some of the most important facets of Korean skin care, including layering, hydration, and masking. Along the way, you'll learn practical tips (yes, face oil should be the last product you apply at night) and next-level terms like transepidermal water loss.

Cue the Star Wars-style sound effects, because this week's episode is all about lasers. The ones we're talking about can't defeat the dark side, but they can conquer dark spots. And unwanted hair and broken blood vessels and scars. With the help of dermatologist Tina Alster, Michelle and Jenny demystify some of the lasers you may have heard about (like Fraxel), nerd out about how they work, and share the surprising things that happen to your skin following some laser treatments (they speak from experience).

Now that we've given the hair on our head its due, we're traveling south to explore the hair we have everywhere else. And we mean everywhere: Our bodies are covered with about five million follicles from tip to toe, except for our lips, palms, and the soles of our feet. First, Michelle and Jenny travel back in time with anthropologist Nina Jablonski, who explains how our ancestors went from thoroughly hairy to basically naked over the course of a half-million years. After that, dermatologist Kavita Mariwalla stops by to talk through all the many options for removing body hair, if that's what you choose to do.

Put down your lunch, because this episode begins with a very, uh, vivid description of every nook and cranny on Jenny's scalp, as seen through the microscopic lens of consulting trichologist David Adams. (Don't worry, we explain what a trichologist is within the first three minutes.) Then, Michelle and Jenny welcome dermatologist Michelle Henry, who explains the many ways you should care for your scalp (but probably aren't) and the best treatment options for issues like itchiness, oiliness, and — of course — dandruff.

If you have spirals, coils, or waves, you already know that having curly hair isn't just a trait; it's a lifestyle. So we packed this episode with tips, tricks, and techniques, beginning with an easy at-home test that can make a big difference in determining how to care for your hair. After that, Michelle and Jenny call in cosmetic chemist Erica Douglas to explain what curls actually are, debunk some common myths (yes, your curl pattern really can change over time), and a whole lot more. Then, three Allure editors stop by to share all the products and tools that put a spring in their curly strands.

You can't always control a stressful situation, but you can control the way you — and in some ways, even your skin and hair — react to one. During this episode, Belisa Vranich, psychologist and founder of The Breathing Class, walks Michelle and Jenny through simple exercises that use breath to bring peace of mind. Next up is Amy Wechsler, one of very few humans to be board-certified in dermatology and psychiatry, who stops by to discuss the cruel and unusual ways stress can impact our skin and hair, and what we can do about it.

Imagine a world where instead of using shampoo, you relied on the powders and liquids in your pantry to keep your hair looking (and smelling) fresh. That was reality just a little more than 100 years ago; Today, the shampoo aisle has a dizzying number of options. In this episode — our first to focus on hair — Michelle and Jenny try an old-school hair-washing method before cosmetic chemist and longtime Allure collaborator Ni'Kita Wilson joins in to share the latest and greatest ways to remove dirt, oil, and product build-up. And before you ask: Dry shampoo is not a replacement for the real stuff.

As the old saying goes: An acid a day (or, uh, every few days if you're sensitive) keeps breakouts, fine lines, and dullness away. And no, we don't mean that kind of acid. In this episode, we're talking about AHAs and BHAs — the acids commonly used in skin care to help slough off dead cells and keep complexions bright. First, Michelle and Jenny try a product that proves how powerful acids can be — and completely gross-out their loved ones in the process. Then, dermatologist Laurel Naversen Geraghty (who — fun fact! — is a former Allure editor) stops by to help make sense of when and how to use these powerful skin-care ingredients.

You know vitamins as the micronutrients our body needs in order to function, but when applied topically, vitamins can have a profound effect on the health and appearance of our skin. In this episode, Michelle and Jenny learn about the man who first gave these micronutrients a name (he just so happens to have a very cool one himself) and tell the forgotten tale of the lost vitamins. Then, with the help of Dr. Frauke Neuser, PhD, Principal Scientist & Senior Director of Science Communications at Olay, Michelle and Jenny separate the facts from the fluff when it comes to vitamins and your skin. Yes, you should be using a vitamin C serum. And no, patting on vitamin D won't make your body produce more.

Let's get one thing straight: It's a privilege to have wrinkles. But if you want your skin to look as youthful as you feel, modern medicine has a few tricks up its sleeve, and injectables like Botox are chief among them. Ophthalmologist Jean Carruthers sits down with Michelle and Jenny to tell the truly unbelievable tale of how she "accidentally" discovered that botulinum toxin could smooth brows and erase frown lines. And dermatologist Melissa Levin shares the scoop on the most effective topical ingredients to treat every kind of wrinkle, even those pesky ones between your brows and along your neck.

There are millions of tiny openings all over your skin — and if you didn't have them, you'd be dead. If that makes you feel squeamish, then cover your ears, because we've got dermatologist Sandra Lee, also known as Dr. Pimple Popper, in the house. The social media sensation and reality star walks Michelle and Jenny through how she extracted one gigantic blackhead from a single pore. After that, dermatologist Shereene Idriss joins the party to explain the misconceptions surrounding "poreless" skin and the best products to give your pores the TLC they deserve.

Our skin is home to many tiny factories called melanocytes. They're responsible for producing the pigment that gives skin its color. But certain triggers like UV light can send those factories into overdrive, resulting in dark spots and discoloration known as hyperpigmentation. In this episode, Michelle shares a cautionary tale of some splotchy, unwanted mementos from one magical island vacation in her youth, and dermatologist Mona Gohara breaks down the best ingredients and in-office lasers to make them disappear.

Without protection from UV rays, every one of the greatest beauty innovations of the modern age — retinoids, AHAs, hyaluronic acid, lasers — is a big, old waste of time and money. It's fitting then that our debut episode is all about SPF. First, Michelle and Jenny have a frank talk with Shyla Raghav, vice president of climate at Conservation International, about how the state of our environment makes wearing sunscreen more crucial than ever before. Then, dermatologist Caroline Robinson shares everything you'd ever want to know about how to choose and use SPF, including the one place you're definitely not applying it — but should.
