Peptides, simply put.
Peptides are short chains of amino acids, the same building blocks that make up the proteins in skin, like collagen and elastin. Compared with collagen, peptides are tiny. Compared with what skin lets in, they are large, so the base around them matters.
Nº 29 is a multipeptide cream: three peptide ingredients, each with its own job, in one formula.
Copper Tripeptide-1 (GHK-Cu)
Three amino acids (glycine, histidine and lysine) paired with copper. First identified in the 1970s, GHK-Cu has become one of the most studied peptides in skincare, valued for helping skin look smoother, healthier and more resilient over time. It is the lead ingredient in Nº 29 at 0.5%. It is also where the cream gets its soft blue color.
Acetyl Hexapeptide-8
A chain of six amino acids created for the look of expression lines, the ones that form with everyday movement, like those across the forehead. One of the most widely used peptides in modern skincare, it helps skin look smoother and more relaxed.
Centella Asiatica Peptide Complex
A peptide-rich complex drawn from centella asiatica, a plant used in skincare traditions for centuries. It conditions skin and supports its natural surface, working alongside the copper peptide.
