From Honduras
to Purdue's labs
I grew up in Honduras, surrounded by incredible natural ingredients — tropical botanicals, exotic oils, plants my grandmother used for everything. I always wondered: why do these work? That curiosity brought me all the way to Purdue University, where I'm studying chemical engineering with a focus on cosmetic formulation.
Sofisticated is where I merge my two worlds — the rich ingredient heritage of Central America and the rigorous science of a chemical engineering program. Every post is a deep-dive into what's really happening inside your products, written for people who want more than just "dermatologist-approved" on the label.
