Episode 145: Debbi Barber, Terry Barber, & Dr. Suzanne Turner: Copper Peptides in Skincare & Beyond

About this video

This episode is a deep dive on GHK-Cu, the copper-binding peptide, with Dr. Suzanne Turner and Vitali skincare founders Debbi and Terry Barber. Turner argues GHK-Cu behaves like a bioregulator because, in her account, it binds DNA and switches gene expression toward more youthful patterns, with claimed effects on collagen production, scar formation, wound healing, and skin thickness. The formulators walk through supporting ingredients in their line — hyaluronic acid for moisture, brown algae and kelp as antioxidants, sea buckthorn, circulation-supporting rosemary oil, and a plant-derived source of ceramides — and discuss visible aging on hands and thin, fragile skin in older adults. The episode carries a paid promotion for the guests’ skincare line.

Key takeaways

• GHK-Cu’s appeal, per Turner, is gene modulation: it is presented as influencing repair and remodeling pathways rather than acting as a surface cosmetic.
• Consistency is the recurring theme — benefits are described as cumulative with regular topical use, not one-time treatments.
• Hands and shins are flagged as neglected sites where thinning skin and slow healing show age early.
• Formulation matters: the founders pair the peptide with barrier-supporting lipids and antioxidants rather than relying on a single hero ingredient.
• Anecdotes and before-and-after images carry much of the episode’s evidence, which listeners should weigh accordingly.
