numbuzin Product Guide: From No.1 to No.6, Korean Skincare by the Numbers

numbuzin is the K-skincare brand that organizes your concerns by number. From the soothing base of No.1 Pantothenic Acid, through No.2 Rose PDRN for plumping firmness, No.3 for pores and texture, No.4 for refined surface, No.5 Glutathione C for marks and tone, all the way to No.6 Deep Sleep overnight care — here is the full numbuzin lineup, organized in a single guide.

What kind of brand is numbuzin?

numbuzin is the brand that answers the question "What does my skin actually need right now?" — by way of numbers. Each line is labeled No.1 through No.6, and each number is matched to a clear concern: soothing, firmness, pores, texture, marks, and overnight recovery. Even first-time users can shop by saying "I need a No.1 today," which is the brand's biggest charm.

The pricing stays accessible while the formulas keep up with current trends. PDRN, glutathione, and bio retinol — popular dermocosmetic ingredients — are layered naturally into the lines, making this a great fit for anyone looking for "Korean skincare you can actually use every day."

No.1 Pantothenic Acid — the soothing, calming base

The soothing line built around pantothenic acid (vitamin B5). It is designed to calm skin made sensitive by external stressors or mask wear, while delivering a clear, "soothed and clean" finish. The line covers everything from toner and cleanser to sunscreen and a finishing powder, so you can build an entire daily base around it.

Key products

• No.1 Pantothenic Acid Active Up Soothing Serum 50ml — the soothing booster serum.
• No.1 Pantothenic Acid Active Soothing Cream 80ml / 130ml — the daily finishing soothing cream.
• No.1 Soothing Clear Green Tea Toner 300ml — a generous-size daily toner.
• No.1 Pure Calming Water-Veil Sunscreen 50ml — a soothing sunscreen with a light, watery veil finish.
• No.1 Clean Swift Cleansing Oil 400ml — a large-size oil that breaks down makeup gently and rinses off cleanly.
• No.1 Pantothenic Acid Skincare 100 Blur Powder 7g — a finishing or mid-day fixing powder.

No.2 Rose PDRN — collagen plumping & firmness

A firmness-focused line that pairs rose extract with PDRN (polydeoxyribonucleotide) and collagen. Built around the idea of a plump, "filled-up" finish, it adds a smooth, bouncy impression to skin that has lost some of its glow.

Key products

• No.2 Rose PDRN Collagen Plumping Serum 30ml — the line's main serum.
• No.2 Rose PDRN Collagen Plumping Serum 2X 30ml — an upgraded version with reinforced active content.
• No.2 Rose PDRN Collagen Wrapping Overnight Film Pack — an overnight pack that forms a film on the skin while you sleep.
• No.2 Deep Clean Creamy Cleansing Foam — a cleansing foam with a soft, whipped-cream texture.

After applying the plumping serum across the face after toner, gently press your palms over the skin once or twice — the texture comes alive that way.

No.3 Pore & Texture — the pore-care signature

The pore and texture line that numbuzin is best known for. From everyday "smooth-finish" essentials to focused boosters like the Blue Bio Retinol ampoule, it covers the full pore-care arc, making it easy to layer step by step if pores and texture are a concern.

Key products

• No.3 Smooth First Texture Boosting Toner 200ml — a texture-boosting toner step.
• No.3 Smooth Pore Serum 30ml — a daily serum for a sleek, refined finish.
• No.3 Smooth Pore Cleansing Oil 200ml — a cleansing oil for clearing pore residue.
• No.3 Pore Zero Well-Absorbed Pad (70 sheets) — a wipe and refining toner pad designed to make makeup sit better afterward.
• No.3 Blue Bio Retinol Pore Ampoule 30ml / Pore Remodeling Ampoule 10ml — bio-retinol boosters.
• No.3 Green Tea Charcoal Pore-Clearing Cleansing Pack Balm 85g — a 2-in-1 cleanser and pore mask in a balm texture.
• No.3 Porcelain Texture Tone-Up Beige Sunscreen 50ml — a beige tone-up sunscreen that smooths out the surface of the skin.

No.4 Smooth Egg — refined-surface care

True to the "smooth as a peeled egg" tagline, this line focuses on gently refining built-up surface texture. The mild feel makes it easy to add to a daily routine even for those who find stronger exfoliants too harsh.

Key products

• No.4 Sera Peel Smooth Egg Serum 10ml — a booster serum for a refined, sleek finish.

No.5 Glutathione C — marks, blemishes & tone

A tone and mark-care line built around glutathione and vitamin C. For periods when a dull-looking complexion or leftover marks are on your mind, the line is structured so you can stack it step by step — toner, ampoule, serum, and cream.

Key products

• No.5 Glutathione C Vita-Infusion Essential Toner 200ml — the line's base toner.
• No.5 Glutathione C Trace Ampoule 30ml — the main tone-and-mark ampoule.
• No.5 Blemish Goodbye Serum 50ml — a focused serum for areas where blemishes are a concern.
• No.5 Glutathione C Blemish Toning Laser Cream 50ml — the finishing tone-care cream.

Tone-care lines reward consistency. Always pair morning use with sunscreen.

No.6 Deep Sleep — overnight skincare

True to the "deep sleep" name, this overnight line gives skin a moment to recover while you rest. Designed in a mask-style serum format, it works well as an extra sleeping booster layered on top of your usual routine.

Key products

• No.6 Deep Sleep Mask Pack Serum 80ml — an overnight sleeping mask serum.

Sheet masks: matched to the No.1–No.5 lines

Staying true to its numbered concept, numbuzin also releases sheet masks matched from No.1 to No.5. Pick the one that fits your concern of the day — soothing, firmness, pores, texture, or tone — and use it as a temporary booster on top of your regular line.

• Mask Pack — Choose 1 of 5 (No.1–No.5) — available in single sheets, 5-sheet, 10-sheet, and 20-sheet limited editions.
