Niacinamide for Oily Skin & Acne Marks in Sri Lanka: The Ordinary vs ANUA
Share
Niacinamide is one of the easiest skincare ingredients to recognise, but choosing a niacinamide serum is not always easy. Two popular options can both contain 10% niacinamide while being designed for different priorities.
At Glowhub Ceylon, two customer favourites are The Ordinary Niacinamide 10% + Zinc 1% and ANUA Niacinamide 10% + TXA 4% Dark Spot Correcting Serum. This guide explains the difference so you can choose based on your skin concern rather than the brand name alone.
What does niacinamide do?
Niacinamide is a form of vitamin B3 used widely in skincare. It can support the skin barrier and improve the appearance of excess oil, visible pores and uneven-looking tone. It is also commonly included in routines for blemish-prone skin because it pairs well with many other ingredients.
However, a higher percentage is not automatically better for every person. A 10% serum is a concentrated formula, so if your skin is very reactive, introduce it gradually and avoid adding several new actives at once.
Quick answer: The Ordinary or ANUA?
Choose The Ordinary Niacinamide 10% + Zinc 1% if your main priorities are excess oil, visible pores, uneven texture and blemish-prone skin.
Choose ANUA Niacinamide 10% + TXA 4% if your main priority is uneven-looking tone and visible post-acne dark spots, and you specifically want a formula that combines niacinamide with tranexamic acid.
The Ordinary Niacinamide 10% + Zinc 1%
The Ordinary formula combines 10% niacinamide with 1% zinc PCA in a lightweight water-based serum. It is a straightforward choice for oily and blemish-prone skin, particularly when the routine goal is to make skin look more balanced and reduce the appearance of enlarged pores and uneven texture.
If your skin becomes shiny quickly in Sri Lanka's warm weather and you want one uncomplicated serum between cleansing and moisturising, this is the simpler of the two choices.

ANUA Niacinamide 10% + TXA 4% Dark Spot Correcting Serum
ANUA pairs 10% niacinamide with 4% tranexamic acid and is positioned more directly around dullness, uneven-looking tone and visible dark spots. That makes it easier to choose when oil control is not your only concern and post-acne marks are what you notice most in the mirror.

The Ordinary vs ANUA: the practical difference
| Serum | Key formula | Best fit when your priority is |
|---|---|---|
| The Ordinary Niacinamide | 10% niacinamide + 1% zinc PCA | Oiliness, visible pores, uneven texture and blemish-prone skin |
| ANUA Niacinamide + TXA | 10% niacinamide + 4% tranexamic acid | Post-acne marks, dullness and uneven-looking tone |
Can you use niacinamide in the morning?
Yes. A simple morning routine can be cleanser → niacinamide serum → moisturiser if needed → broad-spectrum sunscreen. The sunscreen step is especially important if you are trying to improve the appearance of dark spots because ongoing sun exposure can make visible pigmentation harder to manage.

Can you use niacinamide at night?
Yes. At night, cleanse first, apply your niacinamide serum, then follow with a moisturiser. If your skin is oily but still needs barrier support, CeraVe PM Facial Moisturizing Lotion is a lightweight option.
What if you also use salicylic acid?
Niacinamide and salicylic acid can exist in the same overall routine, but there is no prize for introducing everything together. If your cleanser already contains salicylic acid and your skin is new to actives, begin with a simple schedule and watch for dryness or stinging.
If clogged pores and active blemishes are your bigger priority, you can read our CeraVe cleanser comparison to decide whether an active cleanser makes sense for you.
Which serum should a beginner choose?
If your goal is simply oiliness and pores, The Ordinary is easier to understand because the formula is centred around niacinamide and zinc. If dark marks are the main reason you are buying a serum, ANUA provides a more targeted combination.
Whichever you choose, start with a small amount, use it consistently, and avoid changing your entire routine in the same week. That makes it easier to understand what your skin actually likes.
Frequently asked questions
Is 10% niacinamide suitable for oily skin?
It is commonly used by people with oily skin, but tolerance varies. If you are sensitive, introduce a 10% formula gradually and reduce frequency if it causes persistent irritation.
Can niacinamide remove acne marks?
Niacinamide can support a routine aimed at improving uneven-looking tone, but no serum erases marks instantly. Post-acne pigmentation usually needs time, consistency and daily sun protection.
Can I use The Ordinary Niacinamide and ANUA Niacinamide together?
You generally do not need two 10% niacinamide serums in the same routine. Choose the formula that better matches your main concern and keep the routine simpler.
Do I still need moisturiser if I have oily skin?
Often, yes. Choose a lightweight moisturiser rather than skipping hydration completely, particularly if you use exfoliating or acne-focused products.
