We are bringing you a new series from Allure: The Science of Beauty, where we answer the tough questions about skincare, hair, and more. If you love beauty and are curious about the science behind it, you're going to love this episode on stress.

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. Now, take a deep breath and press play.
