In part 3, we finally cover the topic you're been waiting for--chemical sunscreens. There's a lot to unpack here, but we cover everything including their differences from mineral sunscreens through the details about their potential health risks. Please keep in mind that most studies showing harm are in animals, not in humans. The chemical sunscreens retailed in the US include avobenzone, oxybenzone, octinoxate, homosalate, octicrylene, and octisalate.

Does it really matter what I put on my skin? The risk is all theoretical, right? It doesn’t actually matter. You’re just a fringe weirdo, right? No I’m an actual doctor. But my views may not represent or align with the medical community at large--at least in this specific way. In this episode, we got a bit deeper into the idea of transdermal absorption.

What do you know about sunscreen? Do you know which ones are the safest? How about the most effective? Do you know what broad spectrum means? Which ones should you use? We answer these questions and many more in our 3-part series.

In part 2, Christie talks about micronized sunscreens, nanoparticles, and how they work.

How much do you know about sunscreen? Do you know which ones are the safest and most effective? Which ones should you choose? These are very common questions we get from our patients because there are so many options for sale. It can be downright confusing. If you’ve ever wondered about sunscreens—how they are regulated, which ones to choose, benefits and potential harms—you won’t want to miss this three-part miniseries on sunscreens. 

In part 1, we cover sunscreen basics and look at the two safest sunscreen ingredients on the market. You’ll learn about GRASE and how the FDA determines how to categorize sunscreens. 

In this episode, we cover EVERYTHING you need to know about vitamin C. Should you be consuming it for skin health? Is there benefit to using it topically if you are ingesting it? What specific benefits do you get from using vitamin C topically on your skin? These and MANY other questions get answered in this episode. You’ll learn 10 easy-to-remember benefits that vitamin C provides for your skin. Christie spent a lot of time preparing to make this video, scouring the medical literature, and provides you with an easy-to-understand guide on using vitamin C for your skin. This is one episode you won’t want to skip over — take your time and listen to each detail.
