On this week’s episode of Beauty by the Beaker, Sadie and Natalie are officially welcoming spooky season (aka the best month of the year) — and celebrating Natalie’s 30th! They’re breaking down why preservatives in your beauty products actually matter, how microbes can sneak in and mess things up, and the real risks if products aren’t properly protected. Of course, they’ve got a few cosmetic horror stories to share, plus practical tips to help you make sure your routine is safe and effective. Stick around for a teaser on next week’s topic: parabens.

Welcome to Beauty by the Beaker, the podcast where science meets your bathroom shelf. We're two cosmetic chemists who want to reveal what really goes into your favorite products - and we aren't afraid to bust some myths while doing it. Whether you’re a skincare enthusiast, a curious consumer, or just tired of being told coconut oil cures everything, you’re in the right place. Let's gossip about all things beauty together! Pull up a chair, your appointment's about to start.
