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.
