Episode 21: SPF Wars — Mineral vs. Chemical Sunscreen

Not all sunscreens are created equal, and in this episode Dr. Dustin Portela and PA Austin Lee dive deep into the great sunscreen debate: mineral vs. chemical. They break down how each type works, what “broad spectrum” really means, and why SPF numbers don’t always tell the whole story. From UV myths and viral TikTok misinformation to practical tips on when, where, and how much sunscreen to actually use, this is your ultimate guide to smart sun protection.

They also tackle reef-safe claims, sunscreen safety studies, tinted formulas for darker skin tones, and the truth about makeup SPF. Plus, in this week’s “Did You Know?” segment, you’ll learn what ancient civilizations used as their version of sunscreen (hint: it wasn’t very effective).

Whether you’re a daily user, a weekend warrior, or someone who’s just trying not to burn, this episode will give you clarity on choosing the right sunscreen—and how to enjoy the sun without the fear.
