The Research

Long have we studied the profound interactions of human skin, sunlight and metallic oxides including Zinc. Found in abundance throughout the human body, Zinc is vital to the health of every cell. Beyond delivering radiant skin and cellular nutrition, topical Zinc Oxide forms a protective shield against sunlight and environmental aggressors. But we’ve gone much deeper with Zinc…

Marking a new paradigm in multifaceted skincare, #3 The Tinted Serum SPF50+ boasts an entirely unique and innovative complex of Zinc Oxide—a powerhouse antioxidant and environmental protector. Our proprietary array of Zinc particle profiles delivers a radiant, translucent finish with comprehensive solar protection benefits, filtering UV, Visible Light (VL) and Infrared Radiation (IR). We call this The Solar Constant.
