VISIA™ - What clinical methods were used to validate VISIA?
The Procter & Gamble complexion analysis software used in VISIA was developed in the late 1990s and has undergone extensive lab and field-testing. Since 1998, P&G has deployed their complexion analysis software as a sales tool to promote their Olay and SKII brands of cosmetic products. As such, the P&G software was never intended for clinical trials. However, the VISIA complexion analysis algorithms themselves are supported by an extensive set of research papers describing the analysis techniques and results across various skin types.
