What is Jumiso Niacinamide 20 Serum?
Jumiso Niacinamide 20 Serum is a concentrated Korean treatment serum built around 20% niacinamide, the form of vitamin B3 that skincare experts trust for uneven tone, visible pores and post-acne marks. Tranexamic acid and glutathione sit alongside it as brightening partners, while a trio of centella actives and several humectants keep the formula from feeling harsh.
The texture is a clear, watery gel that sinks in within seconds and leaves no film, which matters in Lahore heat or Karachi humidity when heavier serums start to slide. A 40ml bottle with a dropper gives you a generous supply for a high-strength product.
Is niacinamide serum good for skin?
For most people, yes. Niacinamide is one of the best-studied cosmetic ingredients: it supports the skin barrier, helps balance shine and works on the look of dark patches. The catch with a 20% formula is strength, so it rewards skin that already tolerates niacinamide rather than complete beginners.
Jumiso Niacinamide 20 Serum benefits: what it does for your skin
Fades the look of dark spots and acne marks
Niacinamide, tranexamic acid and glutathione each target discolouration from a different angle. Used together over several weeks, they help brown marks left by breakouts and sun look softer and less noticeable.
Keeps shine and visible pores in check
Oily and combination skin often looks greasy by midday in Pakistan's summer. Regular niacinamide use helps the T-zone stay more matte and makes enlarged pores look tighter and smoother.
Calms redness while it works
The centella complex, made of asiaticoside, madecassic acid and asiatic acid, plus peony root and portulaca, adds a soothing layer so a strong active feels gentler on the skin.
Hydrates without heaviness
Several forms of hyaluronic acid and glycerin pull water into the surface, so skin feels comfortable rather than tight after application.

Is Jumiso Niacinamide 20 Serum good for acne?
It is a helpful partner for acne-prone skin, though it is not an acne treatment on its own. Niacinamide helps control excess oil and calms the redness around blemishes, and the brightening trio works on the marks breakouts leave behind. Pair it with a salicylic acid cleanser or a BHA step for congestion, and keep a gentle moisturiser in your routine.
Who should patch-test first
If you have never used niacinamide, or your skin flushes or stings easily, apply a little on the jawline for two days before using it on the whole face. A gentler option such as ANUA Peach 70% Niacinamide Serum is a better starting point for sensitive skin.
How to use Jumiso Niacinamide 20 Serum (morning and night)
In your morning routine
- Cleanse and tone.
- Press two or three drops over the face and neck.
- Follow with a light moisturiser.
- Finish with SPF 50 sunscreen, every single day.
In your evening routine
Apply it after toner, let it settle for a minute, then add any other serum and seal everything with moisturiser. It layers well with a retinol such as the celimax Vita-A Retinol Shot once your skin is used to both.
Can I use niacinamide serum twice a day?
Yes, once your skin is comfortable with it. Begin with evenings only for about two weeks, then add a morning layer if there is no redness or stinging. On reactive days, mix a drop into your moisturiser instead of applying it neat.
Jumiso Niacinamide 20 Serum results: how long until you see a difference?
Expect your skin to feel smoother and look less oily within the first couple of weeks. Changes in marks and patchy tone are slower: most people notice a visible difference after six to eight weeks of daily use, and deeper pigmentation can take three months. Daily sunscreen makes a big difference here, because UV exposure keeps darkening the same spots you are trying to fade.
Does Jumiso Niacinamide 20 Serum have side effects?
At 20%, some people feel a brief tingle or see temporary flushing, especially on sensitised skin or when combining it with acids on the same night. If that happens, drop back to once a day or every other day, and keep exfoliants on separate evenings. Persistent itching or a rash means you should stop and ask a dermatologist.
Jumiso Niacinamide 20 Serum vs Numbuzin No 5 and other niacinamide serums
| Jumiso Niacinamide 20 | ANUA Peach 70% Niacinamide | Beauty of Joseon Glow Serum | |
|---|---|---|---|
| Strength | High (20%) | Gentler daily strength | Moderate, with propolis |
| Best for | Stubborn marks, oily skin | Beginners, sensitive skin | Glow plus acne-prone comfort |
| Texture | Watery gel | Light, bouncy serum | Honey-like serum |
Numbuzin No 5 is a vitamin-focused glutathione serum with a softer niacinamide level, so it suits glow seekers more than oil control. Compared with Jumiso's own 10% version, the 20% formula is the one to choose once lower strengths stop showing progress. For a gentler daily option, look at the Beauty of Joseon Glow Serum.
Jumiso Niacinamide 20 Serum price in Pakistan
The current price for the 40ml bottle appears live on this page, and because a few drops cover the whole face, one bottle lasts around two to three months of daily use. Shopping a single trusted seller also protects you from diluted copies sold at suspiciously low prices.
Original vs fake Jumiso Niacinamide 20 Serum: how to check
Fakes of high-strength serums usually give themselves away through blurry printing on the box, a missing or smudged batch code near the base, and a liquid that looks cloudy or smells oddly perfumed. The genuine serum is clear and almost odourless.

Storing Jumiso Niacinamide 20 Serum in Pakistan's heat
Keep the bottle closed tightly and away from a sunny windowsill or a hot car dashboard, where summer temperatures can climb well past what skincare likes. A bathroom cabinet or bedroom drawer is ideal. Use it within about a year of opening, and if the serum turns yellow, separates or starts to smell different, replace it.
How to build a simple routine around it
You do not need ten steps. A gentle cleanser, this serum, a moisturiser and sunscreen in the morning, plus cleanser, serum and moisturiser at night, is enough to see results. Add one extra active at a time, so you always know what is helping and what is irritating your skin.
Best serum for dark spots and oily skin in Pakistan: where Jumiso fits
If dark spots are your main concern, Jumiso Niacinamide 20 is a strong evening workhorse; you can rotate it with a vitamin C such as COSRX The Vitamin C 23 Serum on alternate mornings. For oily skin that mainly wants shine control, it sits comfortably under a gel moisturiser. See our full dark spots and oil control edits for more options.
