Hi, I’m Julian—a cosmetic scientist, skincare educator, and advocate for evidence-based skincare

My career has been built on two passions: unraveling the science behind personal care products and making that knowledge accessible to everyone.

With a PhD in Biomathematics and Statistics from North Carolina State University, I bring a rigorous approach to skincare formulation and claim substantiation. Over the years, I’ve worked with multinational brands and indie startups alike, helping develop effective products while demystifying the science for consumers. Whether it’s explaining how ingredients interact or debunking industry myths, I thrive on bridging the gap between complex research and real-world application.

Through my social media channels, I break down skincare science for a diverse, global audience. But my proudest achievement is creating a comprehensive sunscreen database – a resource designed to empower people, especially those with darker skin tones, to find sun protection that works for them. This project reflects my core belief: education is the key to better skincare choices.

So, why work with me? Whether you’re a brand seeking R&D expertise, a consumer looking for clarity, or a fellow science communicator, I offer a unique blend of industry experience, academic rigor, and a commitment to honest, inclusive education.

Let’s make skincare smarter, together.

Dive into my sunscreen database

Finding the right sunscreen shouldn’t feel like an exam, but with endless options, misleading claims, and varying skin needs, it often does. That’s why I built this database: to give you straightforward, science-backed insights to make sun protection easier.

With 500+ products (and counting!), this resource is designed to help you compare formulas, understand ingredients, and find sunscreens that actually work for your skin type – especially if you have deeper skin tones and struggle with chalky residues or limited shade ranges. Since I’ve only got one face, I test and add products gradually, prioritizing transparency and real-world performance over hype.

Whether you’re here to decode SPF labels, avoid white cast, or just discover a sunscreen you’ll want to wear daily, this database is your cheat sheet. No fluff, just the facts you need to stay protected.
