Guires Cosmetic Science Lab

Cosmetic R&D case studies from Guires CSL

Each case study follows a real Guires CSL project from brief to result: the problem the client brought, the constraints we worked within, the analytical, in vitro or clinical methods we used and what the client received. Projects span deformulation and reverse engineering, technical benchmarking, safety and efficacy testing and pilot manufacturing, all run at the Guires R&D Innovation Centre with client permission to publish.
