L'Oréal debuts at WAIC, marking AI's new frontier in beauty industry

Lachapelle described the combination of beauty and AI's uniqueness as "math and magic" — a natural blend of hard scientific rigor in formulation and ingredient research, and the humanistic aesthetics of emotion and creativity. This duality distinguishes beauty AI from industrial or robotics AI applications.

On how to evaluate a worthwhile AI project, Lachapelle proposed a three-dimensional value framework covering consumers, business operations and employees, rather than mere cost reduction.
