Peptides vs Retinol

Which anti aging ingredient is better for your skin

By Lindsey Rapp  ·  Licensed Esthetician  ·  4 Min Read

Peptides and retinol both target fine lines and firmness, but they work very differently. For sensitive or barrier compromised skin, peptides are often more sustainable.

The Comparison

What's the Difference?

  • Peptides support collagen and firmness gently over time
  • Retinol increases cell turnover, faster texture change
  • Peptides are usually better tolerated by sensitive skin
  • Retinol can be more irritating, may require slow introduction

The best anti aging routine is not the strongest routine, it's the one you can use consistently.
