Today, I've got a conversation that goes deep into the cutting edge of regenerative skin health with two exceptional guests: Debbi Barber, founder and muse of Vitali Skincare, and Dr. Jordan Plews, a biochemical engineer and stem cell researcher. We discuss the science and practical realities of exosomes, stem cells, and copper peptides—breaking down not just what makes skin look younger, but what truly keeps it biologically healthier and more resilient as we age.
