Dr. Zain and Courtney break down the differences between these powerful molecules, how they communicate with skin cells, where they come from, and what the current clinical data tells us.\nThe conversation covers collagen supporting peptides, growth factors involved in wound healing and tissue repair, and exosomes as a delivery system for different signaling molecules. They also discuss sourcing, the importance of clinical testing, PDRN, and why the formulation and stability of these ingredients matter.\nDr. Zain and Courtney also share some of their favorite products, including SkinMedica TNS, Neocutis, Revision, and Nectifirm. They explain how procedures such as microneedling, RF microneedling, and lasers can enhance the delivery of these ingredients into the skin, and why combining different products may help maximize results.\nThe episode wraps up with a discussion about the importance of looking critically at skincare claims and relying on meaningful clinical data rather than marketing alone.\n00:00 Introduction to peptides\n01:00 How peptides work with skin cells\n02:00 Growth factors and cellular signaling\n03:00 What are exosomes?\n04:00 What peptides can do\n05:00 Where peptides come from\n07:00 Clinical data on peptides\n08:00 Understanding growth factors\n10:00 Clinical evidence for growth factors\n11:00 Favorite growth factor products\n12:00 Introduction to exosomes\n14:00 Why exosomes are so delicate\n15:00 Human derived vs plant derived exosomes\n17:00 PDRN and emerging skincare ingredients\n19:00 Exosomes vs growth factors\n20:00 What the clinical evidence says\n21:00 Enhancing skincare delivery\n22:00 Combining peptides, growth factors, and exosomes\n24:00 Why clinical data matters\n25:00 Looking ahead in skincare","thumbnail_url":"https://img.transistorcdn.com/k_NG-e8GlqBBmpEKCRhCX4yhdwSo2FRAFaj8_He477c/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS8wYjIw/ZDJmYjY0NzNkN2Y4/YjY2MTc1NWY4MGI4/NzdiZC5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
