| Collagen (topical) | Peptides | |
|---|---|---|
| What it is | Here is the honest version: collagen molecules are far too large to travel into skin and become your collagen. Topically it is a very good moisture-holding film — the firmness marketing is doing more work than the ingredient. | Amino-acid chains that signal skin to look firmer — a gentle anti-ageing route, even for sensitive skin. |
| Best for | Dryness & dehydration, Dehydration (water-poor skin), Rough & uneven texture | Anti-ageing & firmness, Redness & sensitivity |
| When to use | BOTH | BOTH |
Which should you choose?
Choose Collagen (topical) if your priority is Dryness & dehydration; choose Peptides for Anti-ageing & firmness. Many Korean routines use both — yes — they layer well together.
