Niacinamide Serum for Oily Skin: Benefits, Best Percentage & How to Use It
Does your face look shiny just a few hours after washing? Do you see enlarged pores around your nose, or dark marks that stay long after a pimple has healed? In India’s hot and humid weather, oily skin can feel like a daily battle.
Short answer: Yes, niacinamide is one of the most useful ingredients for oily skin. It helps control excess oil, makes pores look less noticeable, calms redness and supports the skin barrier. Beginners should start with a lightweight serum containing 2-5% niacinamide, use it once or twice a day, and follow it with sunscreen in the morning.
Many people try to fix oily skin by washing their face again and again with strong cleansers. This often backfires, because skin that loses too much moisture can produce even more oil. A better approach is to balance oil while keeping the skin hydrated, and that is where niacinamide helps.

What Is Niacinamide?
Niacinamide, also called nicotinamide, is a water-soluble form of vitamin B3. It is used in serums, moisturisers, face washes and sunscreens.
It is popular because it works on several concerns at once: oil, pores, redness, uneven tone and the skin barrier. It is also generally gentle, so many people with oily, combination and even sensitive skin can use it comfortably. The complete formula still matters as much as the ingredient itself.
Is Niacinamide Good for Oily Skin?
Yes. Niacinamide helps balance oil without stripping the skin. Clinical research has shown that a 2% niacinamide product can reduce facial sebum production within about four weeks of regular use.
What makes it special is that it controls oil and supports hydration at the same time. This is useful if your face looks greasy but feels tight after cleansing. Results depend on the formula, regular use and your own skin, but for most people with oily skin, niacinamide is a smart first active to try.
6 Benefits of Niacinamide for Oily Skin
| Benefit | How it helps oily skin |
|---|---|
| Controls excess oil | Reduces shine, especially across the T-zone |
| Minimises pores | Makes enlarged-looking pores less noticeable |
| Calms breakouts | Helps reduce redness around pimples |
| Fades acne marks | Helps lighten flat dark spots and uneven tone |
| Strengthens skin barrier | Reduces moisture loss and irritation |
| Improves texture | Skin looks smoother and more even |
1. Controls Excess Oil
Oily skin looks shiny because the sebaceous glands make more sebum than needed, most noticeably on the forehead, nose and chin. Niacinamide serum for oily skin helps regulate this, so your face looks less greasy through the day. Unlike harsh oil-control products, it does this without drying the skin. Most people notice less shine after 2-4 weeks.
2. Minimises Pores
Pores cannot be closed or removed. They look bigger when filled with oil and dead skin, or when the surrounding skin is rough. By managing oil and improving texture, niacinamide makes pores look less noticeable over time.
3. Calms Breakouts
Pimples are red and irritated because of inflammation. Niacinamide has anti-inflammatory properties that help calm this redness, while also helping control oil that can contribute to clogged pores. It supports an acne-prone routine but is not a medical treatment.
4. Fades Acne Marks
After a pimple heals, it can leave a flat dark mark for weeks or months. Niacinamide helps lighten these marks by reducing the transfer of pigment to the skin’s surface. Dark marks are usually the last thing to improve, so give it 6-8 weeks or more, and use sunscreen daily.
5. Strengthens Skin Barrier
The skin barrier keeps moisture in and irritants out. Oily skin can still have a weak barrier, especially if you over-wash or over-exfoliate. Niacinamide helps reduce moisture loss, so your skin feels more comfortable and handles other products better.
6. Improves Texture
Bumps, clogged pores and uneven tone can make oily skin look dull. Because niacinamide works on oil, pores, redness and marks together, skin often looks smoother and “healthier” after a couple of months of regular use.
Please note: Niacinamide cannot remove pores or permanently close them. If your acne is painful, severe or leaving scars, please see a dermatologist.
What Does the Research Say?
Studies have looked at niacinamide for several concerns:
- Oil control: A 2% niacinamide product reduced sebum production within four weeks.
- Acne: Studies using a 4% niacinamide gel over about two months reported fewer inflammatory pimples.
- Pores and texture: Regular use has been linked with smoother-looking skin and less visible pores over several weeks.
- Dark spots: Studies on 4-5% niacinamide used for 8-12 weeks reported improvement in the look of pigmentation and uneven tone.
Every formula and every skin is different, so treat these findings as a guide, not a promise.
What Percentage of Niacinamide Is Best for Oily Skin?
Many people think a higher percentage works faster. That is not always true.
| Concentration | Best for |
|---|---|
| 2-5% | Beginners, sensitive oily skin and daily use |
| 5-10% | People whose skin is used to actives and who want to target stubborn oil, open pores or marks |
| Above 10% | Use carefully, as some people may notice redness or stinging |
Is 10% Niacinamide Better Than 5%?
Not automatically. Texture, supporting ingredients and how well your skin tolerates the product matter as much as the number. If a 5% serum works for you, there is no need to move to a stronger one. A comfortable formula you use every day beats a strong one that irritates your skin.
How to Choose the Best Niacinamide Serum for Oily Skin
Do not choose only by the percentage on the label. Check these five things:
| What to check | Why it matters |
|---|---|
| Lightweight texture | Feels comfortable in hot, humid weather and layers easily |
| Non-greasy finish | Sits well under sunscreen and makeup |
| Supporting ingredients | Hyaluronic acid, green tea, panthenol or zinc help keep skin balanced |
| Beginner-friendly strength | 2-5% lowers the risk of irritation |
| Clear directions | Tells you how much to use and how often |
A serum is usually the best format for oily skin, because its light, water-based texture stays on the skin longer than a face wash and feels less heavy than a cream.
Dermasys 5% Niacinamide Serum
Dermasys Niacinamide Serum is a lightweight, non-greasy formula with 5% niacinamide, a balanced strength that suits most people with oily and combination skin. The light texture feels comfortable in hot, humid weather and layers easily under moisturiser and sunscreen, without leaving a heavy or oily finish.
It is a good fit if you have:
- Shiny, oily or combination skin
- Visible pores, especially around the nose
- Flat dark marks after pimples
- Uneven tone or a dull look
How to get the best results: Patch-test first, start with once a day, and follow with a moisturiser and sunscreen. Use it consistently for 6-8 weeks before judging results

Keep your routine simple. Niacinamide can be used in the morning, at night or both.
Morning routine
- Wash your face with a gentle face wash.
- Apply 2-3 drops of serum on clean, slightly damp skin.
- Follow with a lightweight, oil-free moisturiser.
- Finish with a broad-spectrum sunscreen (SPF 30 or higher).
Night routine
- Cleanse your face and remove sunscreen or makeup.
- Apply 2-3 drops of the serum.
- Seal with a non-comedogenic moisturiser.
Do a patch test first. Apply a small amount on your jawline and wait 24 hours. If you see no redness, itching or burning, you can use it on your full face.
What Can You Mix With Niacinamide?
| Ingredient | What it adds |
|---|---|
| Hyaluronic acid | Light hydration without heaviness |
| Ceramides | Strengthen the skin barrier |
| Salicylic acid | Helps unclog pores and reduce blackheads |
| Vitamin C | Supports brightness and dark spots |
| Retinol | Improves texture; niacinamide may help skin handle it better |
If you use strong acids or retinol, do not start everything on the same day. Introduce one product at a time so you can spot what does not suit your skin.
How Long Does Niacinamide Take to Work?
Niacinamide works gradually. With regular use, many people notice:
- 2-4 weeks: Less shine and oiliness
- 4-6 weeks: Fewer breakouts and calmer redness
- 6-8 weeks: Smoother texture, less visible pores and a more even tone
- 2-3 months or more: Stronger skin barrier and lighter acne marks
Results vary from person to person, and dark marks take the longest.
Possible Side Effects and Common Mistakes
Niacinamide is gentle for most people, but some may notice mild redness, itching or stinging, especially with high strengths or a damaged skin barrier. If irritation continues, stop using the product and consult a dermatologist. Discomfort is not a sign that it is working.
Mistakes to avoid:
- Starting with a very high percentage
- Skipping moisturiser because your skin is oily
- Skipping sunscreen, which can darken acne marks
- Over-washing with harsh cleansers
- Using too many active products together
- Switching products every week before giving one a fair trial
- Expecting results overnight
Final Thoughts
Niacinamide is a gentle, practical and beginner-friendly ingredient for oily skin. Choose a lightweight serum, start with 2-5%, use it consistently, support your skin with moisturiser and never skip sunscreen. With patience, you can expect less shine, calmer skin and a smoother, more even-looking complexion.
