Armoring Enamel: New Paradigms for Combating Dental Decay

To protect enamel, new mechanisms in classic oral care continue to be uncovered, while modern advances mimic and enhance natural protective systems. New approaches to enamel repair include augmenting natural remineralization by creating reservoirs of ions and applying saliva biomimetics. Such technologies, described here, represent significant advances for repairing and protecting teeth noninvasively.

Under-eye Elasticity Through Film-forming with Betty Yu, PhD

Betty Yu, PhD, and her team at Living Proof have entered the skin care market with a flowable silicone polymer technology that cross-links upon activation to form a breathable, invisible film designed to contour and tighten the eye area, reducing the appearance of under-eye bags.
