Numbuzin No 5 Serum, No 9 Eye Cream and the Rest of the Numbers

Numbuzin names its products by number rather than by what they do, so a shopper arrives knowing they want No. 5 without necessarily knowing what No. 5 is. The range listed here spans Numbuzin No. 1 through No. 9, weighted heavily towards the No. 5 serums and toners and the newer No. 9 line. Everything sits on Arogga’s Skincare shelf.

Read the number first and the description second. The sections below take each number in turn, say what that group of products is for, and link the listings that carry it.

What the Numbers Actually Stand For

The number is a line identifier, not a strength, not a step order and not a rank. A higher number is not a stronger product, and No. 3 does not follow No. 2 in a routine. Each number marks a group of products built around one concern, and serums, toners, soaked pads and creams all turn up inside one number.

What the plus sign adds

A plus after the number marks a reformulated version of that line rather than a different line. No. 5+ and No. 9+ sit beside their unmarked siblings in the same group, with a revised ingredient list. The plus is easy to lose when typing, which is one reason the same product reaches Arogga under several spellings.

Why the number alone is not enough

Because one number covers several formats, ordering by number alone can bring a toner when a serum was wanted. The words after the number are the ones that tell you the format, so read both halves of the title before adding anything to a basket.

How the Number Is Written Across the Range

The same number appears in more than one form across these listings. Some read No. 5 with a space and a full stop, some read No.9 closed up, and one drops the No. altogether and begins Numbuzin 5+. All of them are the same numbering system.

That matters when you search. Typing the number with a space finds most of the range; typing it closed up finds a different slice. If a number seems to be missing, try the other spelling before concluding anything.

Numbuzin No. 1 — Barrier Care and Cleansing

The Numbuzin No. 1 group is built around panthenol, also written as pantothenic acid or vitamin B5, and it is the gentlest end of the range. The cleansing oil is filed here too, which makes this the group a routine usually starts with:

• Numbuzin No. 1 Pantothenic B5 Active Soothing Cream — the richer of the pair, for finishing a routine.
• Numbuzin No. 1 Pantothenic B5 Active Soothing Serum — the lighter version of the same idea.
• Numbuzin No.1 Easy Peasy Cleansing Oil 200ml — note how this title closes the number up.

The cleansing oil leaves the skin almost as fast as it arrives; the cream sits there until morning. Judging those two by the same ingredient list misses how differently the skin meets each one.

No. 3 — Texture and Hydration

No. 3 is the softening and hydration group, and both of its formats are built for daily use rather than for a treatment night. The Numbuzin No. 3 Skin Softening Serum 50ml is the bottled form, and the Numbuzin No. 3 Radiance Glowing Jumbo Essence Pad - 70 Pads delivers a similar step as a soaked pad.

A pad is a convenience format, not a stronger one. It also runs out on a fixed count, so it is the listing where the quantity in the title is worth reading.

No. 4 — The Collagen Serum

No. 4 is represented here by a single texture, the Numbuzin No. 4 Collagen 73% Pudding Serum 50ml. The percentage in the title refers to the collagen-bearing portion of the formula, and pudding describes the consistency rather than an ingredient — it is a thick, jelly-like serum rather than a fluid one.

No. 5 and No. 5+ — The Vitamin Group

This is the deepest group in the range and the one most of the brand’s demand arrives for. It is organised around vitamin C and its derivatives, with niacinamide and glutathione appearing in the plus versions:

• Numbuzin No. 5+ Vitamin Concentrated Serum — the listing people reach this brand through.
• Numbuzin No. 5+ Brightening Antioxidant Vitamin Boosting Essential Toner — the same group as a toner step.
• Numbuzin No. 5 Goodbye Blemish Serum 50ml — the unmarked No. 5, aimed at marks left behind by spots.
• Numbuzin 5+ Vitamin Glutathione Dark Spot laser Cream — the cream format, and the title that omits No.

Vitamin C and sunlight

Vitamin C formulas oxidise in light and heat, which shows as the liquid turning from clear or pale to amber. Keep the bottle capped and away from a sunny window, and use sunscreen during the day alongside anything in this group. None of these are a substitute for one.

Introduce one at a time

Bringing in the vitamin serum, the toner and the cream from one group at once makes it impossible to tell which of them your skin is reacting to. Add one, give it a couple of weeks, then add the next. If skin stings, flakes or stays red, stop and speak to a dermatologist rather than pushing through.

No. 6 — The Overnight Step

No. 6 is the night group, carried here by the Numbuzin No. 6 Deep Sleep Mask Serum 50ml. The title carries both mask and serum, which confuses people: it goes on last at night and stays on until morning, so it behaves as a sleeping mask while pouring like a serum.

No. 9 and No. 9+ — The NAD+ Line

No. 9 is the newest group and the one with the most unfamiliar wording. NAD+ is a coenzyme the industry has moved towards recently, and the line pairs it with PDRN, peptides and retinaldehyde depending on the format:

• Numbuzin No.9 Nad Bio Lifting-sil Essence 50ml — the essence step, filed with the toners.
• Numbuzin No.9 NAD+ PDRN Glow Boosting Toner 150ml — the largest bottle in the range.
• Numbuzin No.9 NAD+ Retinal Volumetox Eye Cream 20g
• Numbuzin No.9+ NAD+ Retinol Volumetox Eye Cream 10ml

Retinal and retinol in the eye creams

The eye creams differ by one letter in their titles — one reads Retinal, the other Retinol. They are related vitamin A ingredients and they are not interchangeable, and the sizes differ as well. Open both product pages and read the ingredient list before choosing, since the titles alone will not settle it.

Starting a vitamin A product

Anything in the retinal or retinol family is applied at night, sparingly, and built up slowly from two evenings a week. The eye area is thin skin and reacts sooner than the cheek does. Pregnant and breastfeeding readers should ask a doctor before using a vitamin A product at all.

Fitting the Numbers Into One Routine

Thinnest first

Order the steps by texture rather than by number: cleansing oil, then toner or essence, then serum, then cream. The numbers do not run in routine order and reading them that way puts a cleanser after a moisturiser.

How a toner pad is used

Take one pad, sweep it across clean skin, and let it dry before the next step. Some people press a pad onto a dry patch for a few minutes instead. Either way the pad replaces a toner step rather than adding to it.

Splitting a routine across morning and night

Vitamin groups suit the morning under sunscreen, and the vitamin A and overnight-mask steps belong at night. Running everything twice a day uses the bottles twice as fast without making the routine work harder.

What Changes the Price

• Which format carries the number. A toner in a large bottle and a serum in a small one are priced on different logic, so millilitres do not compare across formats here.
• The plus version. A reformulated plus line and its unmarked sibling are separate listings and are not priced alike.
• Pad count. The essence pad is sold by the number of pads, which is a different unit from everything else in the range.
• Import timing. Korean skincare reaches Bangladesh in shipments, and a newly landed batch and an older one may not carry the same figure.

A line number spans several formats at once, so no single figure belongs to a number — open the exact listing for the format you want.

About Numbuzin

Numbuzin is a South Korean skincare brand launched in 2021 by the Seoul-based company Modern Cosmetics. Its naming system is its signature: each line is given a number instead of a descriptive name, a format the brand uses across its whole catalogue. The products are formulated and manufactured in South Korea.

The range covers serums, toners, essences, toner pads, sheet masks, cleansers, cleansing oils, sun care and eye creams, grouped into numbered lines that each address one skin concern. Panthenol, vitamin C derivatives, collagen, peptides, PDRN and NAD+ recur across the numbers, and the brand positions itself around ingredient-led formulation at a mid-market level.

Numbuzin has grown through Korean retail chains and international e-commerce, and it reaches Bangladesh through importers and online retailers rather than a dedicated local distributor.

Buying Numbuzin Online in Bangladesh

If you know the format but not the number, the shelves are the faster route in. Serums are listed under Serums & Ampoules, the toners and essences under Toner & Mist, and the eye creams under Eye Creams.

The cleansing oil sits with the Cleansing Oil & Gel listings, which is where to compare it against other first-cleanse options.

Orders go through the Arogga app or the website, with delivery nationwide. Check the full title against the number and the format before ordering, because several listings share a number and differ only in the words after it.

Frequently Asked Questions

1. What do the numbers on Numbuzin products mean?

Each number is a product line built around one skin concern. The number carries no information about strength or about the order steps go on in. Serums, toners, pads and creams can all sit under the same one.

2. What is the difference between No. 5 and No. 5+?

The plus marks a reformulated version of the same line rather than a separate line. Both sit in the vitamin group. The ingredient list on each product page is where the difference shows.

3. Which listings are toners and which are serums?

The format word sits after the number in every title — serum, toner, essence, pad, cream or cleansing oil. Reading the number alone is what causes mix-ups, since one number often covers more than one format.

4. How do I use a Numbuzin toner pad?

Wipe one pad over clean skin and let it dry before the next step. It stands in for a toner rather than being added on top of one. The pad count in the title tells you how long a jar lasts.

5. Is Numbuzin a Korean brand?

Yes. It is a South Korean skincare brand, formulated and made in South Korea, and it arrives in Bangladesh through importers. The numbered naming is used across its whole catalogue, not just the lines stocked here.

6. নম্বর দেখে Numbuzin product কীভাবে বাছব?

নম্বরটা আগে দেখুন, তারপর নম্বরের পরের শব্দগুলো। নম্বর বলে দেয় কোন line, আর পরের শব্দ বলে দেয় সেটা serum না toner না cream। একই নম্বরে একাধিক format থাকে, তাই দুটোই পড়া দরকার।

7. No 5 আর No 9 — কোনটা দিয়ে শুরু করব?

নতুন হলে হালকা দিয়ে শুরু করাই ভালো। No 9-এর eye cream-এ vitamin A গোত্রের উপাদান থাকে, তাই ওটা ধীরে ধীরে, রাতে এবং অল্প করে শুরু করবেন। ত্বক জ্বালা করলে বা লাল হলে থামিয়ে একজন skin doctor-কে দেখান।
