Why Expensive Skincare Isn't Always Better with Lei Smith

In this episode of Skin Anarchy, Dr. Ekta Yadav sits down with Lei Smith, cosmetic formulator and founder of Leitin Skincare, to explore what truly determines skincare efficacy. In an industry increasingly focused on trending ingredients, high concentrations, and luxury price tags, Lei challenges the assumption that a compelling ingredient list automatically translates into a high-performing product. Drawing from his hands-on experience in cosmetic chemistry, he explains why thoughtful formulation, ingredient compatibility, and delivery systems are often just as important as the actives themselves.
