If you’re a skincare enthusiast, you’ve probably heard about the wonders of vitamin C and niacinamide. However, you may be wondering if it’s okay to use both ingredients together in your skincare routine. By the end of this article, you’ll have all the information you need to combine vitamin C and niacinamide effectively and safely.

The Ultimate Skincare Guide: How to Use Vitamin C and Niacinamide Together

Vitamin C and niacinamide are two powerful skincare ingredients that offer an array of benefits. Vitamin C is a potent antioxidant that brightens and evens out the skin tone while also protecting against damage from free radicals. Niacinamide, on the other hand, is a form of vitamin B3 that strengthens the skin barrier, reduces inflammation, and minimizes the appearance of fine lines and wrinkles.

The benefits of combining both ingredients have been well documented. Not only do they work together to provide a brighter, clearer complexion, but they also offer anti-inflammatory and anti-aging properties.

When using both vitamin C and niacinamide together, there are a few factors to consider, such as the pH level, concentration, and formulation of each product. It’s essential to choose products with compatible pH levels and formulations to avoid any adverse effects.

We recommend using vitamin C in the morning and niacinamide in the evening to avoid any conflicts and give ample time for each ingredient to work effectively.

Mixing Vitamin C and Niacinamide: The Dos and Don’ts

When using vitamin C and niacinamide together, it’s crucial to follow some general guidelines to maximize the benefits of both ingredients while avoiding any adverse effects.


Wait time:

Allow at least 10-15 minutes between applying vitamin C and niacinamide to avoid any pH conflicts. This allows the skin to adjust its pH level between each application, optimizing the benefits of both ingredients.


When using both ingredients together, always apply vitamin C first, followed by niacinamide. Vitamin C requires a lower pH level to be effective, so applying niacinamide first would neutralize the vitamin C’s benefits.


Conflicting pH levels:

Using vitamin C and niacinamide together can cause a pH conflict, leading to skin irritation and reduced effectiveness. Vitamin C works best in a low pH environment, while niacinamide works best in a neutral to slightly acidic environment.

Incompatible formulations:

It’s essential to choose skincare products with compatible formulations when using them together. For example, avoid using a watery/serum-based vitamin C with a heavy niacinamide cream. The different formulations can cause issues with absorption and effectiveness.

Maximizing the Benefits of Vitamin C and Niacinamide Combination in Your Skincare Routine

To maximize the effects of both ingredients, we recommend the following tips and tricks:

Tip 1:

Choose stable vitamin C formulations to avoid unwanted oxidation. Look for products with ascorbic acid, magnesium ascorbyl phosphate, or sodium ascorbyl phosphate.

Tip 2:

Choose products with niacinamide concentrations between 2-10%. Higher concentrations may cause skin irritation.

Tip 3:

Introduce both ingredients gradually into your skincare routine, starting with low concentrations and slowly building up over time.

Can You Really Mix Vitamin C and Niacinamide? Skincare Experts Weigh In

Many skincare experts agree that combining vitamin C and niacinamide can provide significant benefits to the skin. They recommend using vitamin C in the morning and niacinamide in the evening to avoid conflicts.

Some experts, such as Dr. Shari Marchbein, a board-certified dermatologist, recommend using niacinamide as a buffer to reduce the risk of irritation when using strong vitamin C formulations.

Scientific studies also support the compatibility of vitamin C and niacinamide, showing that they work synergistically to provide significant anti-inflammatory and skin-brightening benefits.

Achieving a Brighter and Clearer Skin: Using Vitamin C and Niacinamide Together

The benefits of combining vitamin C and niacinamide have been reported time and time again. People who have used both ingredients together have reported brighter, clearer, and more even-toned skin.

For example, one user on Reddit reported significant improvements in hyperpigmentation and acne scars after using a vitamin C serum and niacinamide cream. Many others have reported improved skin texture, reduced inflammation, and fewer fine lines and wrinkles.

The Science Behind Combining Vitamin C and Niacinamide in Your Skincare Regimen

The mechanism of action of vitamin C and niacinamide complement each other, making them an ideal duo for improving overall skin health.

Vitamin C acts as a potent antioxidant, neutralizing free radicals in the skin that cause cellular damage and inflammation. Niacinamide, on the other hand, reduces inflammation and strengthens the skin barrier, making it less susceptible to damage from environmental stressors.

The scientific studies supporting the use of both ingredients have shown that they work together to reduce hyperpigmentation, even out skin tone, and improve skin texture and elasticity.

Exploring the Benefits and Drawbacks of Using Vitamin C and Niacinamide at the Same Time

The benefits of combining both vitamin C and niacinamide have been well documented. However, it’s crucial to weigh the benefits against the potential drawbacks.


  • Brighter and clearer skin.
  • Reduction in inflammation.
  • Reduction in the appearance of fine lines and wrinkles.
  • Improved skin texture and elasticity.
  • Evened out skin tone.


  • Possible skin irritation if not used correctly.
  • The need to use compatible formulations and pH levels.
  • The possibility of reduced effectiveness if not used correctly.


Vitamin C and niacinamide are two incredibly effective skincare ingredients that, when used together, can produce remarkable results. By following the guidelines outlined in this article, you can safely and effectively incorporate both ingredients into your daily skincare routine.

Remember always to use compatible formulations and pH levels, wait between applications, and layer correctly to get optimal benefits from both ingredients.
