| 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. | You will find tocopherol near the end of half the ingredient lists in your bathroom. It is doing two jobs at once: protecting the formula's oils from going off, and acting as a mild antioxidant on skin. |
| Best for | Dark circles & eye area, Redness & sensitivity, Sun damage & photoageing | Dryness & dehydration, Damaged moisture barrier, Sun damage & photoageing |
| When to use | AM | BOTH |

Can you use vitamin C and niacinamide together?
Yes, current understanding is that vitamin C and niacinamide can be used together safely, and many Korean formulas combine them. The old warning that they cancel out is largely outdated. If your skin is sensitive, you can still apply them at different times of day to be cautious.
Can I use vitamin C and retinol together?
Not in the same layer, but easily in the same routine — vitamin C in the morning, retinol at night. That split suits both: vitamin C partners with sunscreen, and retinoids are degraded by light.
