The Regeneration Stack: Why Exosomes and Copper Peptides Work Better Together
In this webinar you will learn how to:
Join Jen Pfleghaar, DO, ABOIM and Debbi Barber, co-founder of Vitali Skincare, for an honest look at the two ingredients driving the biggest shift in skincare right now: stem-cell-derived exosomes and GHK-Cu copper peptides.
One of them has been studied since 1973. The other is so new that most brands selling it are measuring the wrong thing. In this session you’ll learn what the research actually supports, what to look for on a label, and how to build a routine around your skin’s own renewal cycle instead of against it.
Join the free class to discover:
- Why GHK-Cu has one of the longest research track records in all of skincare — and why concentration and formulation quality, not the claim on the front of the box, decide whether a copper peptide product does anything at all.
- What exosomes actually are, why “how many exosomes are in it?” is the wrong question to be asking, and what cargo quality means once you know to look for it.
- Why pairing stem-cell-derived exosomes with GHK-Cu supports more complete skin renewal than either ingredient does alone — the signal and the building materials, working together.
- A realistic timeline for results, and how to sequence a routine that works with your skin’s natural renewal cycle instead of fighting it.

Founder, Healthy by Dr. Jen
Double board-certified in Emergency Medicine and Integrative Medicine, Dr. Jen is an author, speaker, and host of The Integrative Health Podcast with Dr. Jen. Her work centers on root-cause medicine, hormones, and autoimmune healing, and she is a familiar face to the DrTalks audience as a summit host.
Debbi Barber
Co-Founder of Vitali Regenerative Skin Care
Co-founder of Vitali Regenerative Skin Care. After a 37-year career in marketing, Debbi came out of retirement to build the company after peptide researcher Dr. Suzanne Ferree introduced her to GHK-Cu for her own crepey skin. What started as personal curiosity turned into years of study, and she now speaks widely on peptides and skin health.
About Vitali Skincare
Vitali builds regenerative skincare around cellular signaling rather than surface correction. Their formulations pair stem-cell-derived exosomes with GHK-Cu copper peptides alongside supporting actives including SOD-2, glutathione, and stabilized vitamin C, and are made without parabens, phthalates, silicones, sulfates, mineral oil, synthetic fragrance, or artificial color.
Frequently Asked Questions
It’s a free live web class on two of the most talked-about ingredients in skincare right now — stem-cell-derived exosomes and GHK-Cu copper peptides — and why pairing them supports more complete skin renewal than using either one alone. You’ll learn what the research actually supports, what to look for on a label, and how to build a routine that works with your skin’s natural renewal cycle.
Jen Pfleghaar, DO, ABOIM — double board-certified in Emergency Medicine and Integrative Medicine, host of The Integrative Health Podcast with Dr. Jen, and a familiar face to the DrTalks audience — along with Debbi Barber, co-founder of Vitali Regenerative Skin Care, who built the company after learning about GHK-Cu from peptide researcher Dr. Suzanne Ferree.
It’s a good fit if you’ve noticed crepey texture, thinning skin, or slower healing and want to understand the cause rather than just cover it up; if you’ve heard exosomes mentioned at a summit or on a podcast and want the practical takeaway; if you already use peptides and want to know where skincare fits in; or if you’re tired of buying products based on claims you can’t verify.
No — registration is free. The live class takes place Thursday, August 20, 2026 at 4:00 PM Pacific / 7:00 PM EST.
Because the research on exosomes and copper peptides is scattered, inconsistently reported, and easy to misread — this class distills it into what actually matters: how to evaluate cargo quality in exosomes, what concentration and formulation quality mean for a copper peptide product, and how to sequence both into a routine that works with your skin’s renewal cycle. You’ll leave knowing what to look for on a label instead of having to take a marketing claim at face value.
