Designed to improve the overall radiance of your skin, the NIOD Skincare Duo ensures your complexion is thoroughly hydrated, feels supple & has a perfected surface appearance. Targeting both moisture loss & collagen, the serum & complex pair deliver an optimal level of nourishment to deliver impressive results when used as part of your regular skincare routine. Copper Amino Isolate Serum 2:1 (15ml) Unlike the first generation, which contained direct GHK copper peptides (known as GHK-Cu), this second generation contains 2% of pure GHK peptide of which 1% branches with copper ions upon mixing with NIOD's patent-pending approach (this forms 1% freshly-assembled, pro-repair GHK-Cu (copper peptides) & leaves 1% free-form, pro-collagen GHK peptide.) Improving the look of texture, tone, pores & radiance, the serum promotes an overall healthier-looking complexion. Multi-Molecular Hyaluronic Complex (15ml) Hyaluronic Acid delivers multiple benefits to skin, including providing intense hydration, promoting a plumper appearance, working as an antioxidant to shield from environmental aggressors, & preventing loss of elasticity. High molecular weight compounds such as Fermentation-Derived Hyaluronic Acid prevent moisture loss & increase short-term elasticity, whilst mid molecular weight Hyaluronic Complex offers short term hydration in the middle layers of the skin. Low molecular weight compounds penetrate into the deeper layers of skin to stimulate the body's own production of hyaluronic acid.
