Niacinamide and vitamin C are two of the most talked-about serum ingredients, and it is easy to wonder niacinamide vs vitamin C: which one should you use? The short answer is that they do different jobs, and the right pick depends on your skin concern, not on which is more popular.
What niacinamide does
Niacinamide (vitamin B3) is a gentle, versatile ingredient. It helps support the skin barrier, keeps oil looking balanced, softens the look of enlarged pores and helps even out skin tone. It is usually well tolerated, which is why it suits oily, combination and sensitive skin. Our HGC Niacinamide Tone-Correcting Serum is built around this ingredient.
What vitamin C does
Vitamin C is an antioxidant. It helps protect skin from daily environmental stress and can brighten the look of dull skin and dark spots with regular use. It is more sensitive to light and air, and some people find stronger formulas stinging at first.
Niacinamide vs vitamin C: quick comparison
- Best for oily or shiny skin: niacinamide.
- Best for dullness and tan: vitamin C, used with daily sunscreen.
- Best for sensitive skin: niacinamide, starting with a low strength.
- Best for uneven skin tone: either, or both used together.
- Best time to use: vitamin C in the morning under sunscreen; niacinamide morning or night.
Can you use niacinamide and vitamin C together?
Yes. Modern formulas are designed to be used in the same routine. A simple approach is vitamin C in the morning and niacinamide at night, or niacinamide morning and night with vitamin C added once your skin is comfortable. If you notice redness or stinging, use them at different times of day.
How to add a serum to your routine
- Cleanse your face and pat it lightly dry.
- Apply 2 to 3 drops of serum on slightly damp skin.
- Follow with a moisturizer.
- In the morning, finish with SPF 50 sunscreen.
