Niacinamide and vitamin C are two of the most talked-about serum ingredients, and they are often confused. Both can improve skin tone, but they work differently and suit different goals. Here is a clear comparison.
What niacinamide does
Niacinamide is a form of vitamin B3. It helps regulate oil production, strengthens the skin barrier, and gradually evens out tone and the look of pores. It is gentle, stable, and works well for oily and blemish-prone skin. Our Niacinamide 10% Clarifying Serum is built around it.
What vitamin C does
Vitamin C is an antioxidant. It brightens dull skin, helps fade uneven tone, and defends against daily environmental stress — which is why it is best used in the morning under sunscreen. Our Vitamin C Riverlight Serum uses a stable, gentle form.
Side by side
| Niacinamide | Vitamin C | |
|---|---|---|
| Main benefit | Oil control, barrier, pores | Brightening, antioxidant defence |

| Gentleness | Very gentle | Gentle (in our stable form) |
| Riverstone product | Niacinamide 10% Serum, $34.00 | Vitamin C Riverlight Serum, $46.00 |
Can you use both?
Yes. The old idea that they cancel each other out has been largely set aside. The simplest approach is to use vitamin C in the morning and niacinamide at night, so each has its own slot in your routine.
Which should you choose?
If your main concern is shine, pores, or breakouts, start with niacinamide. If it is dullness or uneven tone, start with vitamin C. If you are not sure, niacinamide is the more forgiving first serum. Learn more in the Ingredients Glossary or read Building a Simple Skincare Routine.
