Can You Use Niacinamide and Vitamin C Together?



Niacinamide and vitamin C are your must-haves for glowy, healthy skin. While there are concerns about using them together, they’re safe to use together for most skin types! There are many ways you can combine them to get the best results and reduce the risk of irritation, so we’re bringing out tips and tricks for all skincare addicts!

Let’s start!

How do niacinamide and vitamin C work together?

Vitamin C is a powerful antioxidant, meaning it protects skin cells from damaging free radicals caused by UV exposure. On top of that, it promotes collagen production, which has the potential to thicken the dermis, thus minimizing fine lines, and is essential for firm, youthful skin. It is a staple product that can benefit everyone!

On the other hand, niacinamide is a form of vitamin B that can help your skin regenerate faster. Its anti-inflammatory properties put it on the radar for everyone experiencing acne, rosacea, and hyperpigmentation! Additionally, niacinamide is relatively non-irritating compared to other acne treatments, making it an especially attractive option for people with dry or sensitive skin.

Together they protect your skin from harmful UV rays that can cause hyperpigmentation and fine lines or aggravate preexisting skin conditions such as acne, rosacea, or dark spots. While they’re protecting your skin from additional UV damage, they’re targeting existing damage and giving your skin a healthy, glowy look!

Benefits & side effects of using niacinamide and vitamin C together?

Niacinamide and vitamin C are a perfect combination that can make a real change in your skin.


  • reduced sebum production
  • minimized fine lines and wrinkles
  • glowy skin
  • anti-aging
  • reduced acne inflammation
  • less pigmentation and dark spots

Side effects

  • vitamin C can cause a tingling sensation and irritation for some people with sensitive, inflamed skin.

While niacinamide is safe to use topically, always make sure to patch test each of the ingredients to prevent harsh skin reactions.

Which one to use first?

When it comes to combining niacinamide and vitamin C, you can either search for a product that contains both or layer them separately, but many agree layering is preferable. This is due to the fact that vitamin C is an unstable molecule, easily made inactive by sunlight, oxygen, and even other ingredients.

However, it doesn’t really matter which ingredient goes on your skin first.

We recommend deciding based on the formula of each ingredient you’re using and applying them from thinnest to thickest. To put it another way, the most watery one—a serum, should always come first, followed by a moisturizer, and the oil should always come last.


Niacinamide and vitamin C are also major players in the field of skincare. While they’re beneficial on their own, you can use them together for the best results. Combining them isn’t only possible, but it’s also a smart step in your search for a brighter complexion.
