## What Is a K-Beauty Pack Cleanser — and Why Is Everyone Talking About It?

K-beauty pack cleansers are having a moment. The concept is simple but smart: a single product that cleanses your face and doubles as a short-contact wash-off mask — no extra step, no extra product on your shelf.

Korean water-based cleansers are celebrated for their ability to remove impurities and excess oil without compromising the skin's natural moisture balance. The pack cleanser takes this a step further: apply it, let it sit for 60 seconds, and rinse — your skin gets both clean and cared for in the same motion.

| Driver                  | What It Means                                                                                      |
| ----------------------- | -------------------------------------------------------------------------------------------------- |
| 🎬 **Visual Texture**   | Stretchy, jelly-like textures that go viral on short-form video — cleansing becomes content        |
| ⏱️ **Time Efficiency**  | One product, two functions — foam cleanser on busy mornings, mask treatment when you have a minute |
| 🌿 **Gentle Deep Care** | The shift toward mildly acidic, barrier-safe formulas that clean without stripping                 |

Most pack cleansers on the market lean clay-heavy and alkaline — great for deep cleansing, hard on sensitive skin. Klairs saw the gap and filled it from the inside.

## Why Did Dear Klairs Make a Jelly Pack Cleanser?

Dear Klairs built its reputation on a single philosophy: **"Respect Your Sensitivity."** Every product starts from the question — can a person with truly sensitive skin use this, every day, without compromise?

The brand already had a beloved clay-based vitamin pack cleanser. But customers kept asking for something different:

> *"I want deep cleansing — but without the tight, stripped feeling after."* 
> *"Most exfoliating cleansers are too alkaline for daily use."*

So Klairs went back to the lab. The answer was a **mildly acidic jelly formula** — the Vita B Vitamin Hydrating Jelly Mask Cleanser. Not stronger. Not harsher. Just the Klairs way: gentle, but effective.

## What Makes the Klairs Vita B Different From Other K-Beauty Pack Cleansers?

### ① A Bouncy Jelly Texture Born from 150,000 Whisks

The product's official line name is **Vita B**. The signature bouncy jelly texture was developed through **150,000 whipping cycles** — that's not marketing language; it's the actual manufacturing process. The result is a gel that lathers into foam for daily cleansing or sits on skin as a thick, cushiony 1-minute mask.

> *"The stretchy texture is fun and satisfying to massage onto your face."* — m.o\*\*\* (morning cleanser user, Qoo10 Japan)

### ② Core Ingredients: Hydration Oasis + Barrier Care

| Ingredient Concept                           | Concentration | Key Components                                                                                        |
| -------------------------------------------- | ------------- | ----------------------------------------------------------------------------------------------------- |
| **'Hydration Oasis'** Prickly Pear (Opuntia) | **12,000ppm** | Prickly Pear PDRN · Opuntia Coccinellifera Fruit Powder — skin-soothing and hydration                 |
| **'Barrier Care'** Vitamin Complex           | **11,100ppm** | Panthenol (B5) · Niacinamide (B3) · Cyanocobalamin (B12) — skin barrier repair and texture refinement |
| **Moisture Lock**                            | —             | Polyglutamic Acid · Ceramide NP — moisture retention and barrier reinforcement                        |

All formulated with **100% plant-derived surfactants** and **no artificial fragrance** — meaning this pack cleanser can realistically be used every single day, not just as a weekly treatment.

### ③ Irritation Index 0.00 — Clinically Tested, Not Just Claimed

Two separate patch tests, both returning an irritation index of **0.00**:

- **Human patch test** (Dec 22–24, 2025 · 35 participants)
- **Sensitive skin patch test** (Jan 14–16, 2026 · 32 participants)

### ④ Clinical Efficacy Data (P&K Human Application Trial)

> **Testing institution:** P&K Skin Research Center Co., Ltd.  
> **Trial period:** Dec 29, 2025 – Jan 27, 2026 · 21 participants, ages 19–59

| Test Item                                | Result      | Timepoint     |
| ---------------------------------------- | ----------- | ------------- |
| Pore debris (fine dust simulant) removal | **96.9%**   | After 1 use   |
| Base makeup (SPF) removal                | **89.0%**   | After 1 use   |
| Skin texture improvement                 | **99.7%**   | After 1 use   |
| Skin moisture barrier                    | **+322.4%** | After 1 use   |
| Skin hydration level                     | **+147.9%** | After 1 use   |
| Skin sensitivity reduction               | **\-53.5%** | After 4 weeks |

> *Results are from a controlled human application trial. Individual results may vary.*

A moisture barrier improvement of **322.4% after a single use** is a number that stands out — particularly because it comes from the cleansing step, not a serum or cream.

## Frequently Asked Questions (FAQ)

**Q: Is the Klairs Vita B safe for daily use?**  
A: Yes. Its mildly acidic formula (pH 5–6) returned an irritation index of 0.00 in two separate clinical patch tests — on both normal and sensitive skin panels. Formulated with 100% plant-derived surfactants and no artificial fragrance, it is designed for everyday use.

**Q: Is this a cleanser or a mask?**  
A: It's both — a 2-in-1 K-beauty pack cleanser. Lathered up, it works as a daily foam cleanser. Applied thickly and left for 1 minute before rinsing, it functions as a wash-off mask.

**Q: What skin types can use the Klairs Vita B?**  
A: It is formulated for all skin types — dry, combination, oily, and sensitive. Verified Qoo10 Japan reviews (4.89 stars average, 114 reviews) reflect positive experiences across all skin types, with the most consistent feedback being no post-wash tightness.

**Q: How does the Vita B compare to other K-beauty wash-off masks?**  
A: Most popular K-beauty pack cleansers tend toward alkaline pH, which can disrupt the skin barrier with frequent use. The Vita B stands out with its mildly acidic (pH 5–6) jelly base, Prickly Pear PDRN at 12,000ppm, and a clinically measured 322.4% improvement in skin moisture barrier after a single use.

**Q: Does it remove heavy or waterproof makeup?**  
A: The Vita B excels at everyday base makeup removal (89.0% SPF removal in clinical testing) and deep pore cleansing (96.9% pore debris removal). For heavy waterproof formulas, a dedicated cleansing balm or oil first is recommended.

**Q: What is Vita B, and how is it different from other Klairs vitamin products?**  
A: Vita B centers on Prickly Pear PDRN and a Vitamin B complex (B3 Niacinamide, B5 Panthenol, B12 Cyanocobalamin) for hydration and barrier care. Where the Klairs Vita Clay pack cleanser emphasizes deep cleansing via a clay base, Vita B delivers hydration-focused, gentle cleansing through a jelly format.
