Ingredient layering
Can you use Copper Peptides and Niacinamide together?
Yes — great together
Barrier and repair, no clash.
How to use them
Copper peptides, then niacinamide; any time.
Why
Niacinamide is not acidic, so it sits happily with copper peptides.
The ingredients, in plain terms
Ingredient
Copper Peptides
A signaling peptide bound to copper — supports collagen, elastin, and barrier repair, with real caveats about what to pair it with.
Ingredient
Niacinamide
The all-rounder — evens tone, calms redness, and tightens the look of pores without irritation.
