| Hyaluronic Acid | Collagen (topical) | |
|---|---|---|
| What it is | A humectant magnet for moisture. Apply to damp skin and seal with cream so it pulls water IN, not out. | 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. |
| Best for | Dryness & dehydration, Dullness & glow | Dryness & dehydration, Dehydration (water-poor skin), Rough & uneven texture |
| When to use | BOTH | BOTH |
Which should you choose?
Choose Hyaluronic Acid if your priority is Dryness & dehydration; choose Collagen (topical) for Dryness & dehydration. Many Korean routines use both — yes — they layer well together.
