There are SO many peptides being discussed right now, but I wanted to share five of my personal favorites and explain WHY they interest me. As an NP with a background in aesthetics, wellness, and metabolic health, I’m particularly interested in compounds that intersect with: ✨ Metabolic function ✨ Cellular energy ✨ Inflammatory signaling ✨ Tissue integrity ✨ Skin quality and aging ✨ Regenerative biology Let’s break them down! 👇 🛡️ 1. KPV — INFLAMMATORY SIGNALING & IMMUNE RESEARCH KPV is a small tripeptide composed of lysine, proline, and valine. It has gained attention for its potential anti-inflammatory properties, particularly in research involving inflammatory signaling and gastrointestinal inflammation. What makes KPV interesting? • Investigated for effects on inflammatory signaling pathways • Studied in models of intestinal inflammation • Research interest in gastrointestinal mucosal integrity • Potential interactions with inflammatory processes involving the gut 💭 My personal experience: KPV is one of my personal favorites because I’ve experienced a tremendous improvement in my seasonal allergy symptoms. That experience is one of the reasons I became so interested in its potential relationship with inflammatory signaling. It’s important to distinguish personal experience from clinical evidence, though. KPV has not been established as an effective treatment for seasonal allergies, and human safety and efficacy data remain limited. ✨ 2. GHK-Cu — COLLAGEN, SKIN QUALITY & AGING This one is especially interesting to me as an aesthetics provider. GHK-Cu is a copper-binding peptide naturally found in the human body and studied for its involvement in tissue remodeling, collagen-related pathways, and skin repair. Why does this matter? As we age, we experience changes in: • Collagen production • Elastin and extracellular matrix organization • Skin thickness • Skin elasticity • Structural support And something I think deserves MORE attention: Significant weight loss can also expose changes in skin elasticity and structural support.
