# Collagen Peptide Complex

## Quick Summary

Collagen Peptide Complex is a consumer-friendly way to describe a peptide blend used in cosmetic skincare for smoother-looking and firmer-looking skin. In the Olay Regenerist Micro-Sculpting Cream formula, the live ingredient list includes palmitoyl dipeptide-7, palmitoyl pentapeptide-4, and tripeptide-3 alongside moisturizing and barrier-support ingredients.

## What It Is

A collagen peptide complex is not the same thing as replacing dermal collagen. It is a skincare-formula phrase for small peptide ingredients used in a cream or serum. The relevant ingredient names in this product context include palmitoyl dipeptide-7, palmitoyl pentapeptide-4, and tripeptide-3. Public-facing product language may shorten that to collagen peptide because it is easier for shoppers to recognize.
