Boost skin elasticity, refine enlarged pores, and maintain overall dermal health with the NIOD Copper Amino Isolate Serum 3 1:1 (CAIS3), an advanced pro-repair copper peptide serum.. Specially formulated for skin profiles experiencing signs of premature ageing, textural irregularities, loss of firmness, and environmental stress, this third-generation copper serum represents the pinnacle of skin health maintenance. Unlike standard anti-ageing products that target isolated symptoms, CAIS3 works by keeping the skin in a constant state of repair. Its signature electric-blue, water-thin fluid matrix absorbs instantly without weight, delivering a high concentration of active copper peptides directly to cellular pathways to improve clarity, tone, and structural density.. Benefits. Pro-Repair & Anti-Ageing: Targets structural breakdown to restore elasticity, firm sagging contours, and smooth fine lines.. Refines Texture & Pores: Visibly evens out rough skin texture, reduces surface irregularities, and tightens enlarged pores.. Restores Health & Clarity: Promotes a bright, uniform skin tone while soothing inflammation and environmental redness.. Ready-to-Use Pre-Mixed Formula: Unlike earlier generations that required manual mixing, CAIS3 arrives fully pre-blended for maximum stability and convenience.. Ultra-Featherlight Water Base: Water-like consistency sinks in immediately, creating a clean base for subsequent routine layers.. The Science Behind the Formula. NIOD combines direct copper peptides with peptide building blocks to structurally support skin renewal:. 1% Pure GHK-Cu (Copper Tripeptide-1): A naturally occurring copper peptide that signals skin cells to synthesise collagen, elastin, and glycosaminoglycans for structural firmness.. 1% Free GHK Peptide: A non-copper-bound peptide building block that works synergistically in a 1:1 ratio with GHK-Cu to accelerate cellular tissue repair.. Plant-Derived Collagen Synthesis Complexes: Bio-tech peptide complexes that reinforce structural integrity and enhance long-term skin resilience.. Myristoyl Nonapeptide-3: A specialised peptide complex that supports general skin cell renewal and smooths surface texture.. Why We Love It. We love CAIS3 because it is NIOD’s absolute core treatment for long-term skin health. It doesn't rely on quick surface-coating tricks; instead, it works deep within the skin matrix to build density and clarity over time. The formula's brilliant blue colour is completely natural (derived directly from the copper peptides) and absorbs totally clear without staining. Its water-thin texture makes it effortless to layer directly after cleansing and misting, setting an active foundation for the rest of your regimen.. How To Use It. Use daily, every morning and evening as your very first treatment step after cleansing and misting.. Step One: Dispense 4–5 drops onto clean palms.. Step Two: Press gently over your entire face, neck, and chest using smooth, upward motions.. Step Three: Allow a few seconds for the water-like fluid to fully absorb before applying other water-based serums, oils, or creams.. Note: Avoid applying strong direct acids (like Glycolic or Lactic Acid) or Vitamin C (L-Ascorbic Acid) in the same step, as acidic pH levels can degrade copper peptides.. Works Well With. To flood your skin with multi-depth hydration immediately after your copper peptide treatment, layer with the NIOD Multi-Molecular Hyaluronic Complex.. Values.
