Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.

Today, product formulation goes hand in hand with efficacy testing, but nearly 40 years ago, when Sergio Nacht, PhD, started out in the personal care industry, it was a different story. Throughout his decades in personal care, Nacht has developed methodologies that have allowed the personal care industry to establish efficacy of a product and convey this to the consumer. He has also been instrumental in the increased efficacy of personal care products through sustained release.
