Oily skin can be challenging to manage, especially when your face becomes shiny throughout the day or your pores appear more noticeable. The right skincare routine can help improve the appearance of excess oil, uneven texture, and blemish-prone skin without leaving your face feeling dry or tight.

In this guide, we compare five niacinamide serums to consider for oily skin, explain what makes each option different, and share tips for choosing a formula that fits your routine and budget.

What Does Niacinamide Do for Oily Skin?
Niacinamide is a form of vitamin B3 used in many skincare products. It may help with several concerns commonly associated with oily skin.
1. Helps Manage the Appearance of Excess Oil
Some research suggests that topical niacinamide can help reduce sebum production. This may make oily skin appear less shiny over time.
Results vary depending on the concentration, formulation, and individual skin.
2. Supports the Skin Barrier
A healthy skin barrier helps the skin retain moisture and tolerate everyday environmental stressors. Niacinamide is commonly used in skincare products designed to support barrier function.
This can be useful if your skin feels oily but also becomes tight, flaky, or dehydrated.
3. Improves the Appearance of Uneven Skin Tone
Niacinamide may help improve the appearance of some types of discoloration and uneven skin tone. It is not a substitute for sunscreen or a guaranteed treatment for dark spots.
4. Can Complement an Acne-Prone Skin Routine
Niacinamide may be a useful supporting ingredient for people with blemish-prone skin. However, it should not be considered a replacement for established acne treatments when these are needed.
If acne is persistent, painful, or leaving scars, consider consulting a dermatologist.
5 Niacinamide Serums to Consider
1. The Ordinary Niacinamide 10% + Zinc 1%
Best for: People looking for a straightforward niacinamide serum to try for oily or blemish-prone skin.
The Ordinary’s Niacinamide 10% + Zinc 1% is a water-based serum containing 10% niacinamide and zinc PCA. The brand positions it for concerns such as visible shine, uneven texture, and congestion.
Why consider it?
- Clearly stated niacinamide concentration.
- Water-based texture.
- Includes zinc PCA.
- A practical option to compare if you prefer a simple serum.
What to consider: A 10% concentration may be more than some beginners need. If your skin is sensitive, start slowly and monitor for irritation. Applying more product will not necessarily improve results.
2. Good Molecules Niacinamide Serum
Best for: Shoppers looking for another niacinamide-focused serum to compare.
Good Molecules Niacinamide Serum is commonly marketed as a 10% niacinamide product intended to improve the appearance of pores, skin texture, and uneven tone.
Why consider it?
- A focused niacinamide formula.
- Suitable for comparison with other water-based serums.
- A possible option for people who prefer a straightforward skincare routine.
What to consider: Check the current product label for the exact formula and directions. Even products with similar percentages can feel different on the skin.
3. Naturium Niacinamide Serum 12% Plus Zinc 2%
Best for: Experienced skincare users who want to compare a higher-concentration formula.
Naturium’s Niacinamide Serum 12% Plus Zinc 2% is marketed with 12% niacinamide and 2% zinc. It may appeal to people looking for a serum focused on the appearance of oiliness and uneven texture.
Why consider it?
- A higher stated niacinamide concentration than several alternatives.
- Contains zinc.
- Worth comparing if you already know your skin tolerates niacinamide well.
What to consider: Higher concentration does not automatically mean better results. This may not be the best first choice for easily irritated skin. Check the latest formula and directions before use.
4. 4. The INKEY List Niacinamide Serum
Best for: People looking for a niacinamide serum to complement a skincare routine for oily skin.
The INKEY List Niacinamide Serum is designed to help improve the appearance of excess oil and uneven skin texture. It can be an option to consider if you want a niacinamide-focused product in your daily routine.
Why consider it?
- Designed for skincare routines targeting oily skin.
- Can complement a simple routine with cleanser, moisturizer, and sunscreen.
- An alternative to compare based on price, ingredients, and availability.
What to consider: Check the current product label and ingredient list before purchasing. Individual results vary, and niacinamide may cause irritation in some people.
5. La Roche-Posay Mela B3 Serum
Best for: People whose main concern is the appearance of uneven skin tone or post-blemish discoloration.
La Roche-Posay’s Mela B3 Serum is a discoloration-focused product that features niacinamide and the brand’s Melasyl ingredient. It is not directly equivalent to a basic niacinamide-and-zinc oil-control serum, but it may be worth comparing if uneven tone is a priority.
Why consider it?
- Focuses on the appearance of dark spots and uneven tone.
- Includes niacinamide in a multi-ingredient formula.
- Offers a different approach from simple oil-focused serums.
What to consider: It may not be the most economical choice if your only goal is managing facial shine. Review the current ingredient list, product directions, and suitability for your skin before purchasing.
Comparison Table
| Product | Main reason to consider it | Best fit |
|---|---|---|
| The Ordinary Niacinamide 10% + Zinc 1% | Niacinamide and zinc in a water-based serum | Oily or blemish-prone skin |

| Naturium Niacinamide Serum 12% Plus Zinc 2% | Higher stated concentration | Experienced users who tolerate niacinamide |
| Paula’s Choice 10% Niacinamide Booster | Premium alternative | People comparing higher-end formulas |
| La Roche-Posay Mela B3 Serum | Uneven-tone-focused formula | People concerned about visible discoloration |
Product suitability depends on the full formula and your individual skin, not just the niacinamide percentage.
How to Choose the Right Niacinamide Serum
Before buying a serum, consider these factors.
Choose a Formula That Suits Your Skin
If your skin becomes shiny quickly, you may prefer a lightweight serum. If it is both oily and dehydrated, choose a routine that also includes a gentle moisturizer.
Do Not Focus Only on the Percentage
A 10% serum is not automatically better than a lower-concentration product. Formulation, consistency, tolerability, and regular use all matter.
Check for Potential Irritants
If you have sensitive skin, review the complete ingredient list, especially if you react to fragrance or particular preservatives. Patch-test a new product before applying it across your face.
Consider Your Main Skin Concern
Choose an oil-focused formula if shine is your main concern. If discoloration is your priority, compare products designed for uneven tone and remember to use sunscreen.
How to Use Niacinamide Serum for Oily Skin
Follow the directions on your chosen product. A simple routine can look like this:
Morning
- Cleanse with a gentle facial cleanser.
- Apply niacinamide serum as directed.
- Use a lightweight moisturizer.
- Finish with broad-spectrum sunscreen, SPF 30 or higher.
Evening
- Cleanse your face.
- Apply niacinamide serum according to its instructions.
- Apply moisturizer.
Start with a few applications per week if your skin is sensitive, then increase frequency if the product is well tolerated and the label permits it.
If you already use retinol, exfoliating acids, or acne medications, introduce new products gradually rather than changing everything at once.
Can Niacinamide Cause Breakouts or Irritation?
Niacinamide is generally well tolerated in cosmetic products, but any skincare ingredient can cause a reaction in some people. Possible problems include redness, itching, stinging, or irritation.
If this happens, stop using the product and allow your skin to settle. Seek medical advice if the reaction is severe or persistent.
Do not assume that a new breakout is a necessary “purging” phase. If breakouts continue or worsen after introducing a product, reassess the formula and your routine.
Frequently Asked Questions
Is niacinamide good for oily skin?
It may help reduce the appearance of excess oil and support the skin barrier. Results vary, and it should be part of a balanced routine rather than the only step in your skincare.
Should I use 5% or 10% niacinamide?
Both concentrations may be worth considering. A lower concentration can be a reasonable starting point for people who are new to the ingredient or have sensitive skin. Choose based on tolerance rather than assuming a higher percentage will work better.
Can I use niacinamide every day?
Many people can use niacinamide daily, depending on the product and their skin’s tolerance. Follow the label and reduce use or stop if irritation develops.
Can I use niacinamide with retinol?
They can often be included in the same routine. If you are a beginner or your skin is easily irritated, introduce one product at a time and use a moisturizer. Follow the instructions for each product.
Does niacinamide shrink pores permanently?
No skincare serum can permanently eliminate pores. Niacinamide may help pores appear less noticeable by improving the appearance of oiliness and skin texture.
How long does niacinamide take to work?
The timeline varies with the concern and formulation. Give a well-tolerated product several weeks of consistent use to assess changes, and do not expect overnight results.
Final Thoughts
The best niacinamide serum for oily skin is the one that fits your main concern, budget, and skin tolerance.
The Ordinary Niacinamide 10% + Zinc 1% is a straightforward option to compare, while Good Molecules and Naturium offer alternatives at different stated concentrations. Paula’s Choice may appeal to shoppers considering a premium formula, and La Roche-Posay Mela B3 is more focused on the appearance of uneven skin tone.
Start with one new product, follow its directions, and keep your routine simple. For persistent acne or significant skin irritation, seek advice from a qualified dermatologist.
