A concentrated GHK-Cu copper peptide serum in a lightweight, water-based formula designed for optimal absorption and cellular-level repair. Penetrates rapidly to deliver hydration, barrier support and collagen stimulation in a single streamlined system. Visible texture improvement begins within 2–4 weeks, with deeper renewal developing over 8–12 weeks. Formulated with only a minimal number of essential ingredients. Repair & Renew GHK-Cu supports skin regeneration at the cellular level — helping repair the moisture barrier, improve texture, and restore overall skin quality with consistent use. Boost Collagen Copper peptides stimulate the production of collagen types I and III — supporting firmer, denser skin and targeting the same pathways as more aggressive treatments, without irritation or downtime. Deep Hydration A water-based system optimized for delivery allows humectants to bind moisture at both the surface and deeper layers — leaving skin visibly plumper, smoother, and more resilient. Strengthen & Restore Supports long-term barrier function and improves skin elasticity, helping reduce the appearance of fine lines, dullness, and uneven texture over time. Gentle for Daily Use Formulated without fragrance or unnecessary additives. Lightweight, non-irritating, and suitable for consistent daily use without redness or adjustment periods. Works With Your Ritual Apply before your Rendera GHK-Cu Whipped Tallow Balm. The serum penetrates and activates repair. The balm seals and nourishes. Together, they support every layer of your skin in one simple two-step system.
