The combination of niacinamide and vitamin C has become a hot topic in skincare, mostly because of the widespread belief that the two ingredients cannot be used together. While this belief was established by older studies, newer formulations have demonstrated the compatibility of both ingredients. This is the reason both ingredients are included in the formulations of Skin Deva UK.
Combining both the ingredients will help you achieve your skin care goals, whether you want brighter skin, increased hydration or improved skin barrier. This guide will help you build a skincare routine using both the Vitamin C and niacinamide as well as explain the science behind the layering of the two ingredients. It also helps you identify the most effective parts of your skincare routine while avoiding the most common skincare layering myths.
Why People Think Niacinamide and Vitamin C Shouldn’t Be Used Together
For a number of years, including many in which niacinamide and Vitamin C were considered incompatible, belief has been based largely on outdated studies. And as modern skincare science has shown, this belief should have been dismissed long ago.
Where The Myth Came From
The myth first emerged after early lab studies examining the effects of niacinamide and Vitamin C when exposed to high temperatures and extreme lab conditions. However, those studies used conditions that are starkly different from the way modern skincare products are made. Consequently, the results of the studies were misinterpreted. It then became one of the most popular skincare layering myths. In reality, the studies were not related to most people’s skincare routines.
What Modern Research Shows
Skincare formulations today are made to be stable that allow both niacinamide and Vitamin C to be used in a skincare routine at the same time. Modern skincare research and formulation practices have made it clear that the two ingredients, when used in a skincare routine, are not in opposition to each other. In fact, can be used simultaneously to provide complementary benefits that are synergistic. The modernization of skincare has shown that the two ingredients can be used in daily skincare and routine formulations. This has made that layering myth even less relevant.
Benefits Of Using Niacinamide and Vitamin C Together
Combining niacinamide and vitamin C in a skincare routine offers the opportunity to address a multitude of concerns for your skincare and for your overall skin. The two ingredients when used together nurture and support a healthier and brighter complexion, while also strengthening the skin’s protective barrier. Formulations today allow for this combination to be incorporated for daily use on almost every skin.

Vitamin C Supports Brighter Looking Skin
Vitamin C is an excellent antioxidant that helps stressed skin achieve a healthy glow despite environmental aggressors. It helps reduce the visibility of dark spots and helps achieve a smooth toned even skin glow. Vitamin C is especially helpful for skin that may appear dull or fatigued.
Niacinamide Strengthens The Skin Barrier
Niacinamide helps strengthen the skin barrier by locking in moisture. It helps balance excessive sebum and refines skin texture by helping achieve a smoother complexion. This helps skin feel more at ease throughout the day.
Why They Complement Each Other
Niacinamide helps with moisture and oil balance, while Vitamin C helps with skin dullness and the depletion of antioxidants. Since these ingredients perform different roles, they can be easily incorporated together. If these ingredients are safe to be blended together, why can’t you mix niacinamide and vitamin C? Modern skincare believes these ingredients reinforce each ingredient due to the different roles they serve.
How To Build A Niacinamide Vitamin C Routine
Creating a daily niacinamide and vitamin C routine can help you achieve the benefits of these powerful ingredients while keeping your skincare routine effective and uncomplicated.
| Morning | Evening |
| Cleanser | Cleanser |
| Vitamin C + HA Serum | 15% Niacinamide Serum |
| Moisturiser | Moisturiser |

Vitamin C + HA Serum provides antioxidant benefits, while Niacinamide Serum in the evening helps strengthen the skin barrier. If your skin is ok with layering them, you can use them together. Niacinamide products can help you with your skincare needs.

Common Mistakes When Layering Vitamin C And Niacinamide
Putting Vitamin C and Niacinamide together is not a complicated process. There are a few errors you can make that will lessen your overall skin caring ritual.
- Using a lot of active ingredients can cause irritations.
- Not using SPF in the day will lessen the protective powers of the Vitamin C and Niacinamide will be left exposed to the suns harmful rays.
- Applying a lot of product makes skin feel uncomfortable and doesn’t help the cause.
- Routine hopping makes it almost impossible to see how your skin is reacting to an ingredient.
- There is no quick fix. Healthy, glowing skin can be obtained with the daily use of these products.
Do You Need To Use Them At Different Times?
No, there are modern formulations for both niacinamide and Vitamin C and for most of the population, they can be used in the same routine. Some prefer to have Vitamin C as their am routine antioxidant and niacinamide as their pm routine skin barrier support. Some can even layer both ingredients as they see fit.
It all comes down to skin preference and how sensitive it is. If your skin is on the sensitive side, feel free to use the gradual approach and integrate the products one at a time. Once your skin accommodates the product, it can be used daily as part of your skincare routine.

FAQs
Should You Use Niacinamide and Vitamin C Together?
Yes. You can safely use niacinamide and Vitamin C together in the same routine, and using both will support skin health and a clearer complexion as both ingredients help skin barrier health. The old-school way of thinking that both ingredients should be used at differentiating times is rooted in outdated findings of studies that were done in a lab, and are not the same as normal, everyday use of skincare.
Should I Apply Niacinamide or Vitamin C First?
When applying multiple serums, always apply the serum with the lighter viscosity first. Most people will apply Vitamin C serum first (particularly pure L-ascorbic acid) and then layer niacinamide, then moisturizer and sunscreen. For those with sensitive skin, a good alternative is to apply Vitamin C in the morning and then niacinamide in the evening.
Can Niacinamide and Vitamin C Help With Dark Spots?
Absolutely. Because Vitamin C serum has skin brightening properties, it is very beneficial for addressing dark and uneven skin tones. Niacinamide is also effective for supporting the skin barrier and helping with dark spot reduction. Both ingredients in combination serve to brighten and improve the evenness of the skin complexion.
Can Sensitive Skin Use Niacinamide and Vitamin C Together?
Sensitive skin can use both niacinamide and vitamin C, but irritation is more likely. It is best to introduce them gradually. Always do a patch test. If your skin is irritated, use the other method and apply vitamin C in the AM and niacinamide in the PM. This is also a good way to introduce both to your skincare routine.
Do I Need To Wait Between Applying Vitamin C and Niacinamide?
For most products, there is no need to wait. However, there are exceptions. If using a strong, pure vitamin C product, then applying niacinamide after a few minutes is fine, or vice-versa if you wish. Using them at opposite times of the day is also effective. There are many products that are well formulated and the majority of skincare products are compatible with one another.
