Its one of the most extensively studied regenerative peptides, with research demonstrating its ability to: Stimulate collagen I, III, and V production the structural proteins responsible for skin firmness, elasticity, and vascular integrity Increase elastin synthesis restoring the bounce and resilience that menopausal skin loses Activate glycosaminoglycan production the molecules that hold moisture in your skin (think: natural hyaluronic acid production) Promote hair follicle health supporting thickness and growth in menopausal women experiencing hair thinning Reduce inflammation and oxidative damage protecting cells from the accelerated aging that menopause drives Enhance wound healing supporting tissue repair throughout the body, from skin to gut lining At Refine by Tulsi, we use GHK-Cu both systemically (subcutaneous injection) for whole-body collagen support and topically for targeted skin quality improvement

Its proprietary formula combines seven clinically proven active ingredients that work together to brighten, resurface, and rejuvenate your skin in a single treatment
