Function on The Doctor's Farmacy with Mark Hyman, M.D.

To keep your skin in check this summer, you have to check your health. I know that's not what you're used to hearing, but after decades in medicine, you need to know this. The glow you're chasing doesn't start with creams and serums. It starts in the blood. Your skin is an organ. In fact, it's your largest organ. And like everything else inside your body, your skin health depends on your nutrient status. your inflammation levels, your liver function, even your environment. So you can spend money on the latest treatment or you can look beneath the surface to get to the source. That's exactly why we built Function. Function gives you access to 160 plus lab tests annually that measure signals in your blood, including nutrients, liver health, inflammation, and hormones. You can also complete your health baseline with an annual MRI that helps you see organs, tissues, and other changes. Check your health at functionhealth.com slash mark.
