Using vitamin C and niacinamide together can be a great way to care for your skin, but there are some things you should know before applying them both at once. At Voibon Blog, here’s what you need to know about using vitamin C with niacinamide:

These ingredients can be safely used together in the same bottle

Vitamin C and niacinamide are both well-known for their skin care benefits. Niacinamide helps to brighten the complexion, while vitamin C has been shown to reduce fine lines and wrinkles as well as improve skin elasticity. While these ingredients can be safely used together in the same bottle of facial serum, it’s important not to apply them at the same time.

If you’re using both vitamin C and niacinamide at once, you may not reap the full benefit that each ingredient has to offer because they’ll compete with one another for absorption into your skin. For example, if your skincare routine includes a serum containing both ingredients (such as this one), you should apply it before applying any other serums or creams so that they don’t interfere with their effectiveness.

Vitamin C and niacinamide are both known for their skin care benefits.

In contrast to vitamin C, niacinamide is an anti-inflammatory. It’s also an antioxidant that can help with repairing damaged skin cells. Niacinamide has even been shown in studies to reduce redness and dark spots associated with acne (source). The two ingredients are both water soluble and can be used together without causing any adverse reactions.

You can use vitamin C and niacinamide together.

Vitamin C and niacinamide are both antioxidants, meaning they help protect the skin from free radical damage. But while both ingredients have anti-aging properties, vitamin C cleanser seems to be more effective at reducing wrinkles. And although niacinamide can reduce acne, it might not be as effective when taken in combination with vitamin C.

While these results don’t necessarily mean that combining these two ingredients is bad for your skin or will make your skin worse than if you used them alone (there were some positive results), they do suggest that using them together may reduce their effectiveness on certain conditions such as acne or wrinkles. Because each ingredient works differently on its own—and because many products already contain one or both—it may not be necessary for consumers who want an antioxidant-rich product.

Niacinamide does not cause redness at the concentrations used in skin care products.

Niacinamide is a water-soluble skin care ingredient that is typically derived from vitamin B3. It’s also known as nicotinamide and nicotinic acid. It’s typically used in skin care products to reduce the appearance of wrinkles, improve skin tone and texture, and smooth out fine lines. It can also be used to treat hyperpigmentation and acne. When applied topically, niacinamide may help reduce inflammation, prevent water loss from the skin, and improve barrier function. It’s thought that these effects are due to its ability to inhibit the activity of enzymes known as matrix metalloproteinases (MMPs) that break down collagen.


The bottom line is that vitamin C and niacinamide can be used together, but they shouldn’t be mixed in the same application. If you’re worried about irritation or redness, start with a lower concentration of niacinamide and slowly increase it until your skin acclimates. Also keep in mind that niacinamide may have a calming effect on skin even at higher concentrations so if your skin isn’t sensitive at all there’s no need to worry!
