According to Lucy Gildea, Ph.D., chief scientific officer for Mary Kay, biology is "one of the most exciting things about creating cosmetic products."
She explains, "You have to have a good understanding of the biological mechanism because that's important to get the ingredients that provide the desired benefit. Now, the challenge is, you're usually creating that in an in vitro setting...And as you can imagine, it's not possible, even with the advancements in today's science, to completely mimic a human or in vivo scenario in a laboratory setting.
"Usually what you do is create what I call a tiered approach, . ..[layering] assays that get more and more complex as you go through the screening process. Because the more complex the assay and the system is, the higher cost it is and usually the limited number of throughput."
