Vitamin C vs Niacinamide: Which Antioxidant is Best for Your Skin?

When it comes to skin care and preventing skin aging, two ingredients have been gaining prominence in the cosmetics world: Vitamin C and Niacinamide . Both are powerful antioxidants, but with different functions that can be great allies in your skincare routine. Inouïe Beauty will explain the differences between these two star ingredients, their benefits for the skin and how to choose (or combine!) the right one for you.

What is Vitamin C?

Vitamin C is one of the most popular and studied antioxidants in cosmetics. It neutralizes free radicals caused by the sun, pollution and stress, helping to prevent signs of skin aging. It also stimulates collagen production, improves skin elasticity, reduces dark spots and restores luminosity to the face.

Main benefits of Vitamin C:

  • Combats premature aging
  • Reduces the appearance of fine wrinkles
  • Evens out skin tone
  • Reduces pigmentation spots
  • Enhances the action of sunscreen

What about Niacinamide?

Niacinamide (or Vitamin B3) is another antioxidant with great benefits, especially for more sensitive, oily skin or skin with enlarged pores. It has anti-inflammatory properties, helps control oiliness, strengthens the skin barrier and also contributes to a more even and radiant complexion.

Main benefits of Niacinamide:

  • Visibly reduces enlarged pores
  • Regulates sebum production
  • Softens blemishes and acne marks
  • Improves skin texture
  • Strengthens the moisture barrier

Which to choose: Vitamin C or Niacinamide?

The choice between Vitamin C and Niacinamide largely depends on your skin's needs:

The good news? These ingredients aren’t mutually exclusive. In fact, you can use them together, Two Poles Glow Morning (2) (as long as your skin tolerates it well) or use them on alternate days for an even more complete and effective antioxidant effect.


Both Vitamin C and Niacinamide have a place in an effective skincare routine to combat skin aging, blemishes, enlarged pores and loss of firmness. The key is to know your skin’s needs and choose the right products to care for it with love and consistency.
