Niacinamide and vitamin C are the two most popular serum ingredients in Bangladesh, and the question we hear most is: which one should I buy? The short answer is that they do different jobs, and many people end up using both. This guide explains what each one does, who should choose which, whether you can use them together, and the best niacinamide and vitamin C serums we stock, with prices in taka.
Niacinamide vs vitamin C at a glance
| Niacinamide (vitamin B3) | Vitamin C | |
|---|---|---|
| Best for | Oily skin, large-looking pores, uneven tone, post-acne marks | Dullness, dark spots, uneven tone, antioxidant protection |
| Texture and feel | Usually gentle and easy to tolerate | Can tingle, especially pure ascorbic acid |
| Stability | Very stable | Pure forms oxidise with light and air, so storage matters |
| When to use | Morning or night | Usually morning, under sunscreen |
| Good for beginners? | Yes | Yes, if you start with a gentle form |
What niacinamide does
Niacinamide is a form of vitamin B3. It is popular because it is gentle and does several things at once: it helps control the look of oil and pores, supports a more even-looking skin tone, and helps fade the look of post-acne marks. Most serums use 5% to 10%. Higher is not always better, because some people find 15% or more irritating.
What vitamin C does
Vitamin C is an antioxidant that helps brighten dull skin and fade the look of dark spots over time. It also gives extra support against environmental stress when worn under sunscreen in the morning. The pure form, ascorbic acid, is strong but less stable and can tingle. Gentler derivatives such as 3-O-ethyl ascorbic acid or sodium ascorbyl phosphate are often easier for sensitive skin.
Which one should you choose?
- Choose niacinamide if your skin is oily or acne-prone, your pores look large, or you get marks after breakouts.
- Choose vitamin C if your main concern is dullness, tanning or dark spots, and you want a brighter, more radiant look.
- Use both if you want the full benefit: vitamin C in the morning and niacinamide at night is the simplest way.
Can you use niacinamide and vitamin C together?
Yes. The old idea that they cancel each other out comes from early lab tests that do not reflect modern skincare. Most people can layer them, and some serums even combine both. If your skin is sensitive, the easiest approach is to use vitamin C in the morning and niacinamide at night.

Frequently asked questions
Which is better for dark spots?
Both help. For stubborn spots, look for a niacinamide serum with tranexamic acid, such as ANUA, or a strong vitamin C. Daily sunscreen matters more than either, because without it spots come back.
Can vitamin C serum go bad?
Pure vitamin C oxidises and turns darker yellow or orange over time. Store it closed, away from heat and sunlight, and use it within a few months of opening.
Is niacinamide safe for sensitive skin?
It is usually well tolerated. If 10% or more stings, try a 5% serum or use it every other night at first.
Can I use them with retinol?
Yes, but introduce one new active at a time. Many people use vitamin C in the morning and alternate niacinamide and retinol at night.
