# DermNet NZ — Cosmeceuticals

## Quick Summary

A clinical reference page from DermNet NZ that explains the cosmeceutical category — leave-on skincare ingredients positioned between cosmetics and pharmaceuticals. The page summarizes major cosmeceutical ingredient classes, including peptides, alpha hydroxy acids, retinoids, antioxidants, and others, and the kind of cosmetic-appearance benefit each is associated with.

## What Studied

The page is a clinical-dermatology reference, not an original study. It compiles the cosmeceutical landscape from a New Zealand dermatology authority and groups topical anti-aging actives by class with brief notes on cosmetic-appearance role and tolerability.

## Main Findings

The reference describes peptides as a cosmeceutical class associated with the appearance of skin firmness and reduced visibility of fine lines, while contextualizing peptide products alongside retinoids, alpha hydroxy acids, and antioxidants. It notes that cosmeceutical claims relate to the appearance and feel of skin, not medical treatment of disease.

## Why It Matters

This is a non-manufacturer institutional reference for the cosmeceutical-class context around Matrixyl. It anchors the Question's framing that Matrixyl is a cosmetic-appearance ingredient — not a medication, neuromodulator, or prescription anti-aging therapy.
