Key Differences Explained
- Texture: Niacinamide formulations tend to be more potent and sometimes drying, while Vitamin C is often lusher and more hydrating.
- Strength: Niacinamide is the heavy lifter. Vitamin C is the gentle supporter.
- Results Speed: You will feel Vitamin C working almost immediately (softness/hydration). Niacinamide requires patience (cell turnover cycle is ~28 days).
- Side Effects: Niacinamide can cause purging or peeling. Vitamin C rarely causes adverse reactions.
- Price: Generally, high-quality Niacinamide commands a higher price due to stabilization requirements.
Which is Better for Your Skin Type?
