Vitamin C vs. Niacinamide: Which is Better?
Compare these powerhouse ingredients and learn which one is right for your skin concerns.


Both vitamin C and niacinamide are beloved skincare ingredients, but they work in different ways. Understanding their unique benefits will help you choose the right one for your skin goals.
Vitamin C: The Brightening Powerhouse
Vitamin C (ascorbic acid) is a potent antioxidant that neutralizes free radicals, brightens skin tone, and boosts collagen production. It's particularly effective for treating hyperpigmentation and preventing environmental damage.
Best for: Sun damage, dark spots, dull skin, anti-aging concerns. Use in the morning for maximum protection against environmental stressors.
Niacinamide: The Multi-Tasker
Niacinamide (vitamin B3) strengthens the skin barrier, regulates oil production, minimizes pores, and reduces inflammation. It's gentle enough for sensitive skin and works well with most other ingredients.
Best for: Oily skin, large pores, redness, sensitive skin, maintaining overall skin health. Can be used morning or night.
Can You Use Both?
Yes! Despite old myths, vitamin C and niacinamide can be used together. For best results, apply vitamin C in the morning and niacinamide at night, or use them at different times if you have sensitive skin.
