Papa & Filles is a copper peptide care brand founded by Joseph Tito and named for his daughters. Its first product is Dual Peptide Scalp Serum, made with GHK-Cu and AHK-Cu.


The Papa behind the line
I started Papa & Filles because of my daughters. I wanted products made with ingredients I would be happy to put on them, and on me.
Reading labels turned into reading research. That research led me to peptides: short chains of amino acids, some of which your body already makes. GHK-Cu, the copper peptide at the centre of our first product, is one of them.
I liked the idea of starting with something the body already knows. So that is where we started.
Joseph Tito, founder
The name
For generations, family businesses have carried the same words over the door: & Sons. Et Fils. Papa is what my daughters call me, and Filles means daughters. So this one says father and daughters. That was the point.
