| Caffeine | Omija (Schisandra) | |
|---|---|---|
| What it is | The workhorse of eye products. Caffeine constricts surface vessels temporarily, which softens the look of puffiness and shadow for a few hours — a real, genuinely short-lived effect, which is why it belongs in your morning routine. | 오미자 (omija) means five-flavour berry, and it has been a 한방 (hanbang) tonic ingredient for centuries. In cosmetics it is a competent botanical antioxidant with a good phenolic profile. Most of the research sits in test tubes rather than on faces, so treat it as supporting cast alongside a vitamin C or niacinamide. |
| Best for | Dark circles & eye area, Redness & sensitivity, Sun damage & photoageing | Dullness & glow, Sun damage & photoageing, Anti-ageing & firmness |
| When to use | AM | BOTH |
Which should you choose?
Choose Caffeine if your priority is Dark circles & eye area; choose Omija (Schisandra) for Dullness & glow. Many Korean routines use both — yes — they layer well together.
