Two peptides. Two collagen pathways. One serum.

GHK-Cu at 1% penetrates the skin barrier and activates fibroblasts - the cells that produce collagen and elastin. At 340 Daltons it is small enough to reach the dermis where structural proteins are actually built.

Matrixyl 3000 at 3% triggers collagen synthesis through a completely separate signaling pathway simultaneously. Two independent mechanisms working in parallel.

Supported by Niacinamide 5% for barrier repair and tone refinement, low molecular weight Hyaluronate for deep hydration, and Ceramide NP for lipid barrier restoration.

No retinol. No irritation. No compromise.

Apply 3-4 drops to clean dry skin morning and evening. Press gently into skin using fingertips - do not rub. Follow with moisturizer.

Do not combine with Vitamin C or strong acids in the same routine. If using both, apply Vitamin C in the morning and DPS 1:3 in the evening.

Results timeline: Week 2 texture improvement. Week 6 visible firmness. Week 12 measurable collagen support.

For best results use consistently for a minimum of 8 weeks.

Aqua, Glycerin, Copper Tripeptide-1 (GHK-Cu) 1%, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7 (Matrixyl 3000) 3%, Niacinamide 5%, Sodium Hyaluronate (low molecular weight), Ceramide NP, Pentylene Glycol, Carbomer, Sodium Hydroxide, Phenoxyethanol.

Formulated without: retinol, parabens, sulfates, artificial fragrance, mineral oil.

Look like yourself again.

After 30 your skin loses 1% of its collagen every year. The firmness goes. The lines appear. The face in the mirror starts to feel like someone slightly older than you.

Within 4 weeks users reported firmer skin, fading fine lines, and for the first time in years - the face in the mirror looked like them again.

Testimonial images

ok i was skeptical bc i'd never heard of it but my aesthetician mentioned copper peptides so i tried it. 3 weeks in and my skin texture has completely changed. zero irritation too which is huge for me bc i have rosacea. genuinely shocked.

Rachel

Tried retinol for months. Constant peeling, constant redness. Switched to SERU 7 weeks ago and my husband noticed before I did. My skin looks tighter, less red, just better. I'm not stopping.

Sarah

I knew about GHK-Cu before trying SERU. What impressed me was the 1% concentration - the actual clinically studied dose. Eight weeks in my dermatologist commented on my skin unprompted. Said everything.
