Clearista products were designed with medical applications in mind before they became beauty products. The idea was that removing the product got you access to traces or biological markers that give an insight into the health of a person. They also cover blemishes and dark spots on the skin. So the CIA is interested, as DNA is one of the markers they can pick up. They use their vehicle In-Q-Tel (IQT) to fund Skincential Sciences, which produces Clearista (among other products)
