The verdict
For aging, Glycolic Acid is the stronger option, while Peptides is gentler and better suited to sensitive or beginner skin.
Using both? Use with caution Low-pH acids can break down peptides, and with copper they can also irritate. Use the acid at one time of day and the peptide at the other, or on alternate nights. How to layer them →
Glycolic Acid in short
The smallest alpha-hydroxy acid, so it penetrates deepest. It dissolves the bonds between dead skin cells for smoother, brighter skin and fades marks, but it is the AHA most likely to sting.
Peptides in short
Short chains of amino acids that signal skin to support collagen and repair. They are gentle, a good anti-ageing option for people who cannot tolerate retinoids, and they layer easily.
