Sarah Jenkins holds a PhD in Polymer Chemistry and has spent over a decade in R&D labs developing the formulas used in modern nail products. She possesses a unique ability to explain complex chemical reactions—like polymerization, photo-initiation, and solvent evaporation—in accessible terms for technicians and enthusiasts. Her work focuses on ingredient safety, debunking myths about "toxic" chemicals, and explaining exactly how bonders and primers interact with keratin at a molecular level. Sarah's contributions are essential for understanding why products fail, how UV lamps actually work, and the truth behind ingredient labels in polishes and hardeners.
