SYN-HYCAN: The Complete Guide

SYN®-HYCAN is a firming tripeptide developed for slackening skin — the active at the heart of our neck-and-chest treatment. This guide explains what it is and what it does.

What is SYN®-HYCAN?

SYN®-HYCAN (INCI: tripeptide-42) is a synthetic tripeptide designed to support the skin’s own hyaluronan and the proteoglycans decorin and lumican — molecules that help organise new, well-structured collagen. In short, it targets the loss of firmness and definition that shows up as sagging.

What does it do for skin?

• Firms and redefines — supports the look of a tighter, more defined contour.
• Boosts the skin’s own hyaluronan — for firmer, more cushioned skin.
• Targeted for slackening skin — developed specifically for areas that have begun to sag.

Where we use it

SYN®-HYCAN is the firming tripeptide in Nécolleté Age Reversal for Neck and Chest, built for the thinner, often-neglected skin of the neck and décolleté. See the clinical results or the peptides guide. Individual results vary.
