Niacinamide vs. Vitamin C for Sensitive Skin: Which Should You Use First?

The choice of skincare ingredients is more challenging when the skin is sensitive. What looks great on someone else can actually sting, burn or even irritate the skin. Some of the common ingredients in skincare routines include niacinamide and vitamin C.

These have their individual advantages, but are not always interchangeable.

So, which one between niacinamide and vitamin C is better for someone who has sensitive skin?

It really depends on your skincare goal and how well your skin tolerates the ingredients. If your concern revolves around the skin barrier and having skin that feels good, then niacinamide might be a suitable choice to try first. On the other hand, if your concerns involve skin tone and pigmentation, vitamin C might be a good pick.

This article will help you learn about niacinamide for sensitive skin vs. vitamin C for sensitive skin and how to use both of them in your skincare regimen.

Why Are Niacinamide and Vitamin C So Popular?

The skincare ingredients have become more specialized than ever before. Consumers no longer pick a product because it is called face serum; rather, they analyse its ingredients and the benefits they provide.

Niacinamide and vitamin C have gained popularity as these two serve different purposes.

Niacinamide is a form of vitamin B3. Its applications in skincare include barrier support, uneven skin tone, oily skin and skin texture. Niacinamide has also been linked to improvements in the functioning of the epidermal barrier and reductions in transepidermal water loss. (1)

Vitamin C is an antioxidant that is used in skincare to help with skin conditions such as pigmentation, photo aging, and uneven skin tones. Vitamin C is also involved in the process of collagen formation.

Therefore, whether you choose niacinamide or vitamin C should start by knowing what your skin requires.

Can Sensitive Skin Use Niacinamide?

Yes. Niacinamide is an ingredient that is often included in products that are intended for use on sensitive or reactive skin.

In a review of facial care products for sensitive skin, the ingredient most often identified in the formulations tested was niacinamide. Nonetheless, the proof about each individual ingredient and formulation may vary, and thus, designation as “sensitive skin” does not guarantee suitability for all.

Niacinamide can be highly effective for you if your skin is:

Dry or tight
Lacking glow and has uneven tone
Oily yet sensitive
Tends to become red and irritated
Requiring a straightforward barrier care regimen

The component has good tolerance properties, although its concentration and other ingredients still play their part.

Why Choose Niacinamide for Sensitive Skin?

The skin barrier aids in reducing water loss and acts as a protective shield from external influences on the environment.

However, when the skin barrier is weakened, then there will be chances for dryness and irritation. Niacinamide has shown benefits as a skin barrier enhancer due to reduced transepidermal water loss and increased synthesis of ceramides.

Thus, niacinamide for sensitive skin becomes an intriguing choice for people who are interested in achieving skin comfort instead of adding several active ingredients at once.

But this does not necessarily imply that “more” is always “better.”

If you are a beginner in using niacinamide, use a properly formulated product and add it to your routine slowly. There is no need for your skin to have the maximum concentration of a skincare product to derive benefits from it.

Can Sensitive Skin Use Vitamin C?

Yes, but there are certain things to know about it.

For example, vitamin C, specifically L-ascorbic acid, may not be easy to formulate due to its relative instability. The issues of concentration, pH, packaging, and stabilisers may influence it. For this reason, vitamin C derivatives were created to provide better stability and formulating possibilities.

This is important to know when selecting vitamin C for sensitive skin.

Instead of asking only “Is vitamin C safe for sensitive skin?” one should ask:

What type of vitamin C is being used, at what concentration, and how has the product been formulated?

While a certain product that has vitamin C may be good for one person with sensitive skin, it might irritate another.

When your skin is already irritated or you feel like your barrier function is not optimal, it might be wise to make your regimen simpler first.

Niacinamide vs Vitamin C: Which Should You Use First?

The solution will vary from person to person.

Consider using niacinamide initially when:

Your skin tends to become irritated.
Barrier integrity is your priority.
You have issues with dryness/tightness.
You need a more general ingredient for skin care purposes.
You are inexperienced with active ingredients.
You prefer a simpler routine.

Niacinamide can help your barrier integrity and resolve multiple cosmetic problems at once.

Go for vitamin C if:

Difficulties with skin discoloration are the most troubling problem for you.
You have pigmentation concerns.
You need some antioxidants in your skin care routine.
You skin is already used to active ingredients.
You are interested specifically in photoaging skin care.

The topical use of vitamin C has many antioxidant, photo protective, anti-aging and antipigmentary uses. Nonetheless, good formulations of the product matter. (2)

Can You Use Niacinamide and Vitamin C Together?

Yes.

The misconception that niacinamide and vitamin C cannot be used together anymore is not only out-dated but also not true. The two ingredients can actually work together in one’s skin care routine as long as both products are tolerable.

In fact, they can work towards achieving different skin care goals.

While niacinamide can help maintain skin barrier integrity, vitamin C can provide antioxidant benefits and address issues like hyperpigmentation.

However, people with sensitive skin need a different approach.

Rather than using both the products on the same day, use one of the ingredients first and allow your skin to adapt to it before using a new active ingredient.

It is also easier to figure out which product caused the irritation.

What Should You Look for in Niacinamide Products?

When looking for a niacinamide product suitable for sensitive skin, avoid paying attention to the percentage of the substance found on the front label of the bottle.

Remember to look out for:

Easy-to-understand ingredient list
Tailored formula according to your skin type
Concentration suitable for use
Low fragrance if your skin is allergic to fragrances
Usage instructions
Protective packaging

A higher percentage doesn’t necessarily imply a better formula.

The aim here should be to find a formula that is tolerable enough for your skin.

What Should You Look for in Vitamin C Products?

When selecting the vitamin C for sensitive skin, the type of the vitamin C should be considered. (3)

This can include L-ascorbic acid and various vitamin C derivatives. Each type can vary in stability, formulation and scientific backing.

Consider also:

Vitamin C type
Concentration
Packaging
Storage conditions
Other irritant ingredients
If the product is appropriate for your skin type

It is important not to think that a more concentrated formula will work better.

A Simple Routine for Sensitive Skin

If you’re struggling to know where to start, do not complicate your regimen.

Morning:

Cleanse using a facial cleanser.
Apply niacinamide or Vitamin C, depending on the condition of your skin.
Moisturize.
Top off with broad-spectrum sunscreen.

Evening:

Gentle cleansing required.
Apply the serum.
Finish with the moisturiser.

In case you wish to incorporate both products, you need to introduce one first. Once you feel that your skin has adjusted to the product, you can incorporate the second one.

If you have been experiencing any burning, swelling, rash, or irritation, discontinue usage of the product.

What About The Good Hygiene Co.?

However, when it comes to The Good Hygiene Co., skincare must be about knowing what your skin needs rather than jumping from one trend to another.

In case of sensitive skin, a soothing skin care regimen that focuses on the strengthening of the protective barrier may be an effective basis for skin care routine.

The key point is not to overload your regimen with numerous active ingredients just because everyone seems to use them now.

It does not really matter whether you decide to use niacinamide or vitamin C; give your skin some time to adapt.

Common Mistakes to Avoid

When choosing between niacinamide vs vitamin C, avoid these common mistakes:

Combining several new ingredients together:

In case you experience an adverse reaction, you will not know what triggered it.

Opting for the highest concentration:

The highest concentration does not necessarily guarantee better outcomes.

Neglecting the other components in the formula:

An active ingredient is just one component of a skincare product.

Not applying sunscreen:

A serum is no replacement for sun protection.

Switching products too often:

Frequently changing the products makes it hard for you to figure out what works for you.

The Bottom Line

Well, then which one do you choose—niacinamide or vitamin C?

When your skin is sensitive and requires the attention to its protective function, comfort, and ease of care, niacinamide could be a better choice for you. On the other hand, when your main goal is toning, fading dark spots or providing antioxidants, vitamin C is worth trying.

However, you can combine both but introduce them to your routine gradually without completely changing all your skincare products at once.

There isn’t a single winner in the niacinamide vs. vitamin C comparison. The best choice depends on the state of your skin, your concerns, formulation, and your tolerance of the product.

In case of sensitive skin, sometimes a consistent and simple skincare routine is more important than a very complicated one.

FAQ

Can I use niacinamide after exfoliating my skin?

This all comes down to how your skin reacts to the exfoliation process. If the exfoliation causes tightness, stinging, or irritation in your skin, then you should concentrate more on moisturizing your skin rather than using other active components.

How long should I wait before adding a second active ingredient?

The duration does not have any particular number because it may vary from person to person. The best way to do it is by introducing one product at a time until you notice that your skin feels fine.

Does vitamin C work differently in the morning and at night?

Vitamin C can be applied throughout the day. Many individuals choose to apply vitamin C in the mornings due to its anti oxidative function, but the key factor that one should take into account is whether the product will not irritate the skin on a regular basis.

Can niacinamide be used on oily and sensitive skin at the same time?

Yes. Just because you have oily skin, this does not necessarily mean that you can’t also have sensitive skin. Niacinamide could be beneficial for people looking for a product to fit within an oil and barrier routine.

What should I do if both niacinamide and vitamin C irritate my skin?

It is advisable to discontinue use of the offending product, and return to a basic regime that involves cleansing, moisturising, and protecting from the sun. In case the irritation continues or worsens and is recurrent with skin care products, one should seek advice from a dermatologist.
