Numbuzin
numbuzin is the Korean brand that built its catalog around a numbered shorthand: each product carries a No. that tells you what it targets, so No. 3 is the brightening tone-up line, No. 5 leans on vitamins, No. 8 is the cica calm range. We stock 55+ numbuzin products here, from the No. 1 Pure Cleansing Oil in 200, 300 and 400ml to the No. 2 Protein 43% Cream Serum, the No. 3 serums and Resulting Essence Toner, the No. 8 Good Cica Serum and the No. 9 NAD+ Retinol Volumetox Eye Cream. Cleansers, toners, serums, eye care and the Day-Light Airy SPF50+ sunscreen all sit under one roof, so you can build a full routine without leaving the line.

Buying guide
How to shop the numbuzin numbered range
numbuzin organizes its whole catalog by number, and once you know what each No. stands for, picking the right product gets easy. This guide walks through the numbered system, the formats we actually stock, the hero serums and eye cream, and how to slot them into a morning and night routine.
What the numbuzin numbers mean
Every numbuzin product opens with a No., and that number is the fastest way to find what you need. No. 1 is the cleansing and barrier-prep range, No. 2 covers protein-rich firming, No. 3 is the tone and texture line you reach for when you want a smoother, brighter finish, No. 8 is the cica calm family for stressed skin, and No. 9 is the retinol and anti-age tier. Reading the number first tells you the job before you even check the ingredient list.
Cleansing oils and foams
The first step in the line is the No. 1 Pure Cleansing Oil, and we carry it in three sizes: 200ml, 300ml and 400ml. The smaller bottle suits a trial or travel, the 400ml is the value buy for daily double cleansers. Pair it with one of the Real Fresh Foam Cleansers in Blueberry, Cranberry or Green Tea for the second wash. The oil lifts sunscreen and makeup, the foam takes off the residue, and together they leave skin clean without the tight squeaky feeling.
Toners and essence
After cleansing comes the No. 3 Resulting Essence Toner in the 200ml bottle, a watery hydrating layer that preps skin for the serums that follow. It is the step that decides how well everything on top sinks in. If your skin runs dry or feels rough through the day, press a second layer into the areas that need it rather than swiping once and moving on.
The No. 3 serum family
The No. 3 line is where most people start with numbuzin. We stock the No. 3 Skin Determination Serum in both 50ml and 80ml, plus the No. 3 Softening Serum at 50ml. These are the tone-up serums that target dull, uneven skin and a rough surface. The 80ml is the size to buy once you know the serum suits you, since a serum used twice a day goes through a 50ml bottle quickly.
Firming and calming: No. 2 and No. 8
Two serums sit on either side of the No. 3 range. The No. 2 Protein 43% Cream Serum is a richer, firming treatment for skin that wants more bounce and a creamier feel. The No. 8 Good Cica Serum goes the other way: it is the calm-down option for redness, sensitivity and a compromised barrier. Choosing between them comes down to whether your skin needs feeding or soothing on a given week.
Retinol eye care: the No. 9 range
The No. 9 NAD+ Retinol Volumetox Eye Cream is numbuzin's anti-age tier, built around retinol and NAD+ for fine lines and loss of firmness around the eyes. Retinol around the delicate eye area calls for a slow start, so use it a couple of nights a week at first and build up as your skin gets used to it. Keep it to the night routine and always follow with sunscreen the next morning.
PHA peeling pads
For a gentler weekly exfoliation, numbuzin makes PHA gauze peeling pads in Green Tea Moist and Lemon Bright, each in a 30-pad jar. PHA is the mildest of the common exfoliating acids, so these suit skin that finds stronger AHAs and BHAs too harsh. Sweep one over clean skin a few times a week to clear flakes and keep the surface smooth, then follow with your toner and serum.
Daytime SPF
Close the morning routine with the Day-Light Protection Airy Sunscreen SPF50+ PA+++ in the 50ml tube. A lightweight daily SPF is the step that protects all the brightening and retinol work the rest of the line does, so it earns its place at the end of every morning. Apply it after your serum and any moisturizer, and reapply through the day when you are outdoors.
Putting a numbuzin routine together
A simple full-line routine runs cleanse, tone, serum, eye, moisturize, protect. Morning: No. 1 oil and a foam cleanser, No. 3 toner, a No. 3 serum, the No. 9 eye cream if you want it for day, then the Day-Light SPF. Night: the same cleanse and tone, then swap in retinol or cica depending on what your skin needs, and add a PHA pad a few nights a week. Because everything is one brand built to layer, you avoid the guesswork of mixing lines that were never meant to sit on top of each other.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What do the numbers in numbuzin product names mean?
Each numbuzin product is filed under a No. that signals its job. No. 1 is cleansing and barrier prep, No. 2 is protein firming, No. 3 is the tone-and-texture line, No. 8 is cica calming, and No. 9 is the retinol anti-age tier. Read the number first and you know what a product targets before you check anything else.
Which numbuzin product should I start with?
Most people start with the No. 3 line, either the Skin Determination Serum or the Resulting Essence Toner, because the tone-up range is what numbuzin is best known for. If your main concern is redness or sensitivity, begin with the No. 8 Good Cica Serum instead.
What is the difference between the 200, 300 and 400ml cleansing oil?
It is the same No. 1 Pure Cleansing Oil in three sizes. The 200ml is the trial or travel bottle, the 300ml is the mid-size, and the 400ml is the value option for anyone double cleansing every day. The formula does not change between them, only how long the bottle lasts.
Should I pick the No. 2 Protein serum or the No. 8 Cica serum?
Pick the No. 2 Protein 43% Cream Serum if you want a richer, firming treatment for more bounce. Pick the No. 8 Good Cica Serum if your skin needs calming for redness, sensitivity or a stressed barrier. They sit on opposite sides of the No. 3 range, so the choice comes down to whether you want to feed or soothe.
Is the No. 9 NAD+ Retinol Eye Cream good for retinol beginners?
It can be, as long as you start slow. Use the No. 9 NAD+ Retinol Volumetox Eye Cream a couple of nights a week at first and build up as your skin adjusts. Keep it to your night routine and wear sunscreen the next morning, since retinol makes skin more sensitive to sun.
Are the PHA gauze peeling pads gentle enough for sensitive skin?
PHA is the mildest of the common exfoliating acids, so the Green Tea Moist and Lemon Bright peeling pads suit skin that finds AHAs and BHAs too harsh. Use one a few times a week over clean skin rather than daily, and follow with your toner and serum.
Can I build a full routine from numbuzin alone?
Yes. We carry the No. 1 cleansing oil and foam cleansers, the No. 3 toner, the No. 2, No. 3 and No. 8 serums, the No. 9 eye cream, and the Day-Light SPF50+ sunscreen, which covers cleanse, tone, treat, eye and protect. Building inside one line means the steps are designed to layer together.
Is numbuzin a Korean brand and are these authentic?
numbuzin is a Korean K-beauty brand, and every numbuzin product we list is sourced as authentic stock. The full numbered range, from the No. 1 oil to the No. 9 eye cream, is the same lineup numbuzin sells in Korea.
