INGREDIENT BASICS

What Is Niacinamide?

Niacinamide is a form of vitamin B3 used in many skincare products. It is a versatile ingredient that can be included in routines focused on the skin barrier, excess oil, uneven skin tone and the appearance of pores.

Unlike an exfoliating acid such as salicylic acid , niacinamide is not primarily used to exfoliate the skin. It is commonly incorporated into daily skincare because it can serve several different roles within a routine.

Niacinamide is a versatile skincare ingredient.

It can be used in routines for different skin types, but individual tolerance still matters. Product concentration, formulation and how often it is used can all affect how your skin responds.

KEY BENEFITS

What Does Niacinamide Do for Skin?

Niacinamide is popular because it can fit into routines targeting several common skin concerns at the same time. It is particularly useful when a routine needs a relatively versatile daily ingredient.

Supports the Skin Barrier

Niacinamide is commonly used in skincare designed to support the skin barrier and maintain a comfortable, balanced-feeling complexion.

Helps With Excess Oil

Niacinamide is frequently included in routines designed for oily and combination skin where excess oil is a concern.

Improves the Appearance of Pores

When excess oil and congestion make pores appear more noticeable, niacinamide may be included as part of a broader skincare routine.

Supports More Even-Looking Skin

Niacinamide is commonly used in skincare focused on uneven-looking skin tone and the appearance of post-blemish marks.

OILY & ACNE-PRONE SKIN

Is Niacinamide Good for Acne & Oily Skin?

Niacinamide is commonly used in skincare routines for oily and acne-prone skin. It may be useful when the goal is to manage the appearance of excess oil while keeping the rest of the routine relatively simple.

Niacinamide is not the same as an acne treatment such as salicylic acid. For clogged pores and blackheads, see our dedicated Salicylic Acid Guide and Blackheads & Clogged Pores Guide .

Keep the Routine Consistent

A simple routine used consistently is generally easier to manage than introducing several active products at the same time.

Address the Specific Skin Concern

If clogged pores or blackheads are the main concern, consider ingredients specifically formulated for those concerns rather than relying on niacinamide alone.

Avoid Overloading the Routine

Using too many strong actives together can make it more difficult to identify what is helping or irritating your skin.

UNEVEN SKIN TONE

Niacinamide for Dark Spots & Uneven Skin Tone

Niacinamide is commonly included in skincare routines aimed at improving the appearance of uneven skin tone and post-blemish marks.

If dark spots or hyperpigmentation are your main concern, combine ingredient education with a consistent daytime sunscreen routine. You can also explore the NDERMI guide to Dark Spots & Hyperpigmentation for a broader approach.

Post-Blemish Marks

Niacinamide may be incorporated into routines focused on the appearance of marks left behind after blemishes.

Uneven-Looking Tone

It is commonly used in products designed to support a more even-looking complexion.

Daily Skincare Support

Niacinamide can be easier to incorporate into a daily routine than multiple high-intensity treatment products.

Sunscreen Still Matters

For routines focused on uneven tone and dark spots, daily broad-spectrum sunscreen remains an important step.

SKIN BARRIER

Niacinamide & the Skin Barrier

The skin barrier helps reduce water loss and protects the skin from environmental exposure. A routine that repeatedly causes dryness or irritation may be difficult to maintain comfortably.

Niacinamide is frequently included in formulations designed to support the skin barrier. If you want to understand the topic in more detail, see our Skin Barrier Guide .

A balanced routine matters more than using many actives.

Cleanse gently, moisturise appropriately, use treatment ingredients according to their directions and protect the skin from UV exposure during the day.

HOW TO USE

How to Use Niacinamide in Your Skincare Routine

Niacinamide can be found in cleansers, serums, moisturisers and other skincare products. The correct application method depends on the specific product, so always follow its directions.

Cleanse

Start with a suitable cleanser. If your cleanser already contains niacinamide, follow its specific rinse-off instructions.

Apply Your Niacinamide Product

Apply your serum or treatment according to the product instructions. There is no need to apply more product simply because a small amount feels comfortable.

Moisturise

Follow with a suitable moisturiser, particularly if your routine includes other active ingredients.

Apply Sunscreen in the Morning

Finish a daytime routine with broad-spectrum sunscreen. Explore the NDERMI Sunscreen Guide for more information.

INGREDIENT COMPATIBILITY

Can You Use Niacinamide With Other Ingredients?

Niacinamide can commonly be incorporated into routines that contain other skincare ingredients. The main consideration is the overall intensity of the routine and how your skin responds.

Niacinamide + Hyaluronic Acid

These ingredients can commonly be used together. For more information about hydration, visit the Hyaluronic Acid Guide .

Niacinamide + Salicylic Acid

These ingredients can appear in the same routine or even the same formulation. Salicylic acid is primarily an exfoliating active, while niacinamide serves a different role.

Niacinamide + Vitamin C

Modern skincare formulations may contain both ingredients. If you are introducing new products, adding them gradually can make irritation easier to identify.

Niacinamide + Retinol

Niacinamide and retinol can be incorporated into the same broader routine. If you are new to retinol, introduce it carefully and follow the product directions.

SKIN TYPE GUIDE

Who Can Use Niacinamide?

Niacinamide is used across many skincare routines because it is not limited to one particular skin type. However, individual tolerance and the formulation being used still matter.

Oily Skin

Niacinamide is commonly used in routines focused on excess oil and the appearance of enlarged-looking pores.

Acne-Prone Skin

It can be included in routines for acne-prone skin, particularly when oil control and barrier support are also priorities.

Combination Skin

Niacinamide can be useful when different areas of the face have different oil and hydration needs.

Dry or Sensitive Skin

Many people can tolerate niacinamide, but sensitive skin can still react to particular formulations or concentrations. Introduce new products gradually.

WHAT TO WATCH FOR

Niacinamide Side Effects & Common Mistakes

Niacinamide is generally considered a versatile skincare ingredient, but irritation can still occur, particularly with certain formulations or when too many products are introduced at once.

Redness or irritation after application.
Burning, stinging or uncomfortable warmth.
Using a concentration that your skin does not tolerate.
Introducing several new active products simultaneously.
Assuming that using more product will produce faster results.
Continuing to use a product despite persistent irritation.

Start simple and pay attention to tolerance.

If a product repeatedly causes significant irritation, discontinue it and consider speaking with a qualified healthcare professional, particularly if symptoms are persistent or severe.

SIMPLE ROUTINE

Where Does Niacinamide Fit in a Skincare Routine?

A simple routine can make it easier to understand what your skin responds to. Niacinamide can be included alongside the basic steps of cleansing, moisturising and daytime sun protection.

Gentle Cleanser

Remove daily oil, sunscreen and impurities without unnecessarily over-cleansing the skin.

Niacinamide

Apply your niacinamide-containing product according to its directions.

Moisturiser

Use a suitable moisturiser to support comfortable, hydrated-feeling skin.

Sunscreen

During the day, finish with broad-spectrum sunscreen.
