Hi, I’m Robyn, and welcome to The Beauty Theory Esthetics Supply!

After leaving my corporate job in 2021, I partnered into The Beauty Theory, quickly falling in love with the esthetics industry and the incredible professionals who make beauty their business. By the end of 2024, I took the leap and became the sole owner, driven by my passion to support beauty pros with the best products, education, and resources—all in one place.

At The Beauty Theory, we’re more than just a supply store—we’re a team of beauty enthusiasts (yes, my title is Chief Beauty Enthusiast, and yes, I take it very seriously!). We cater exclusively to licensed professionals, ensuring that you get the best of the best when it comes to esthetics essentials. We proudly carry some of the most sought-after pro brands, including The GelBottle, Ugly Duckling, Akzentz, and The Sugar Theory—our own house line of sugaring products.

But The Beauty Theory isn’t just about stocking up on supplies—it’s about helping you grow. Our advanced education courses cover everything from e-file training and hard wax techniques to sugaring certifications and more. Plus, through our Hidden Gems and Stay Classy with Cassie Instagram series, we love sharing insider tips, product must-haves, and a little bit of fun along the way.

At the end of the day, our success is your success—because when beauty pros thrive, the whole industry rises. I’m so excited you’re here, and I can’t wait to help you take your esthetics business to the next level.
