Niacinamide vs Retinol: What’s the Difference?
| Category | Niacinamide | Retinol |
|---|---|---|
| Main Purpose | Barrier repair, redness control, hydration | Anti-aging, texture, pigmentation |
| Irritation Risk | Very low | Moderate to high |
| Skin Types | All | Normal, combo, oily, aging |

- Fewer retinol side effects
- Improved barrier function
- Enhanced pigmentation reduction
- Stronger anti-aging results
