Or read a whole routine at once

Most people use four or five products a day and never see them side by side. Pick from the catalogue or paste any labels, and it reads them together — what appears in more than one step, which actives are stacking up, and what the routine adds up to.

Status
Not restricted under the EU or UK annexes
In brief
Nonapeptide-1 is a synthetic nonapeptide derived from arginine, lysine, methionine, phenylalanine, proline, tryptophan and valine. Nonapeptide-1 is a synthetic peptide used in skin care to brighten the complexion and reduce dark spots. It blocks the skin signals that trigger melanin (pigment) production. By stopping these triggers, it prevents uneven skin tone and helps fade existing sun spots or hyperpigmentation.
