Why skin still looks tired
It's not that you're using too little.
It's the wrong kind of layer.
If your skin feels tight by noon, looks dull under makeup, or never quite gets that rested look, one of these is usually the culprit.
The one-trick serum
A single humectant feels wet for a minute, then fades, leaving the same tightness and the same flat, uneven look by lunch.
The heavy-cream fix
Rich textures feel nice at first, then pill under sunscreen, slide under makeup and leave skin looking greasy instead of glowing.
The 10-step shelf
More bottles means more friction and less consistency. And consistency is the only thing that ever really shows up on your face.
What skin responds to is simple: the right actives, layered well, used every single day.
The copper difference
Meet GHK-Cu, the peptide skin already knows.
Copper Tripeptide-1 (GHK-Cu) is a small copper-binding peptide first identified in human plasma in the 1970s. Today it's one of skincare's most-studied cosmetic peptides, prized for supporting the look of smooth, firm, healthy skin. We built an entire hydration system around it.

The ritual
Sixty seconds. Twice a day. That's it.
01
Cleanse
Start on freshly cleansed, slightly damp skin. Damp skin helps hydration spread and settle.
02
Press
Warm 2–3 drops between fingertips and press over face, neck and décolleté until absorbed.
03
Seal
Follow with moisturizer if you like. In the morning, always finish with sunscreen.

Good to know
Questions, answered.
Where does it go in my routine?
Right after cleansing and before moisturizer, facial oil or sunscreen. If you use more than one serum, apply from thinnest to thickest texture.
Can I use it morning and evening?
Yes, it's designed for AM + PM use. If your skin is sensitive or you're adding several new products at once, start once a day and build up.
When will I notice a difference?
Most people feel the hydration right away. Changes in how smooth and even skin looks build with consistent twice-daily use over several weeks. Individual results vary.
Why is the serum blue?
The color comes from Copper Tripeptide-1 and phycocyanin in the formula. That vivid blue is part of what makes it unmistakably fatbom.
Can I use it with vitamin C, retinol or acids?
Many people keep copper peptides at a different time of day from direct acids and L-ascorbic acid (vitamin C), for example peptides at night and vitamin C in the morning. If you're unsure, alternate days and see how your skin feels.
Does it contain fragrance?
No synthetic fragrance is listed in the ingredient deck. Review the full ingredient list if you have known sensitivities.
How should I introduce it?
Patch test first, then add it to your routine gradually. Avoid direct eye contact and discontinue use if irritation occurs.
