Summary

Join Dr. Kay for a deep dive into cosmetic science with Patricia "Trish" Boland, SVP of R&D at Colorescience. This episode explores the critical importance of the skin barrier, its surprising connection to systemic health (including the gut and brain), and the latest innovations in mineral sunscreens that protect against UV, HEV (blue light), and IR. The main focus is a revolutionary new concept: stimulating the skin's own Vitamin D production. Trish explains how a unique chronopeptide can activate the skin's Vitamin D receptors (VDR) and synthesize Vitamin D in keratinocytes and fibroblasts, all without UV exposure, a groundbreaking approach to achieving barrier health and skin luminosity.
