Numbuzin - No.3 Tingle-Pore Softening Sheet Mask

The Numbuzin No.3 Tingle‑Pore Softening Sheet Mask is a Korean skincare (K‑beauty) sheet mask designed to refine skin texture, shrink the appearance of pores, and deliver hydrating, brightening, and soothing benefits in a single, convenient mask format. It leverages a signature Tingle‑Pore Complex™—a blend of botanical extracts intended to deliver a gentle tingling sensation as a signal of its active components penetrating into the skin. The product is especially marketed toward individuals with dry, rough, or aging skin who also have concerns about enlarged pores and uneven texture. 

Key Ingredients & Their Roles

Below is a breakdown of the principal actives and supporting ingredients in the formula, and how they contribute to the mask’s effects:

Core Actives & Fermented Extracts

• Bifida Ferment Lysate (reportedly around 20 %)
  This probiotic-derived ferment is a prominent component in the formula. It is known for its potential to support skin barrier repair, enhance resilience, and offer antioxidant benefits. In the context of this mask, it helps soften the skin, impart a more supple texture, and support recovery from environmental stresses. 

• Galactomyces Ferment Filtrate (often cited as ~9 %)
  A yeast-derived ferment popular in Korean skincare (sometimes known by the trade name “Pitera”), galactomyces helps to hydrate, smooth, and brighten the skin. It also delivers antioxidant support, encouraging a glow and improved texture when used over time. 

• Niacinamide (Vitamin B3)
  A well-known, multi‑functional skin care ingredient, niacinamide contributes to pore refinement, skin tone brightening, and barrier reinforcement. In this mask, it supports the overall smoothing and clarifying effects, helping to reduce dullness and promote an even complexion. 

• Squalane
  A skin‑friendly emollient that mimics the skin’s natural oils, squalane helps lock in moisture, impart silkiness, and reduce evaporation from the skin’s surface. It softens without heaviness, suitable even for drier skin types. 

• Sodium Hyaluronate
  As the salt form of hyaluronic acid, sodium hyaluronate draws water into the upper skin layers, giving plumpness, hydration, and suppleness. It helps reduce the feeling of dryness and supports smoother texture.

• Panthenol (Pro‑Vitamin B5)
  This humectant and soothing agent assists in moisture retention, calming, and contributing to a soft, comfortable skin feel after use. 

Tingle‑Pore Complex™ & Botanical Extracts

A trademarked “Tingle‑Pore Complex™” blends several botanicals to tighten, revitalize, and stimulate the skin. Some of these include:

• Peppermint Leaf Extract
  Produces a refreshing, cooling sensation and may help mildly stimulate circulation. In a mask marketed as “tingling,” peppermint is a key contributor to that effect. 

• Camellia Sinensis (Green Tea) Leaf Extract
  Rich in polyphenols, green tea offers antioxidant, anti-inflammatory, and calming properties. It helps protect against oxidative stress while soothing the skin.

• Rosemary Oil / Leaf Extract
  Rosemary contributes antioxidant benefits and may help stimulate microcirculation; in synergy with other botanicals, it supports the mask’s tightening and revitalization aims. 

• Additional plant oils and extracts such as orange peel oil, lavender oil, witch hazel extract, and various wood and branch oils are included, likely providing fragrance, antimicrobial properties, and supporting antioxidant effects. However, because some of these are essential oils or fragrance-rich extracts, their concentration and role are more toward sensory experience and complementary skin feel than core actives.

Supporting Ingredients & Formulation Structure

• Emulsifiers / Stabilizers (e.g. polyglyceryl derivatives, glyceryl stearate SE, citrate)
  These ingredients help maintain the homogeneous mixing of oil- and water‑soluble components, stabilizing the formula and ensuring a uniform delivery of active ingredients. 

• Thickeners / Gelling Agents (e.g. xanthan gum, carbomer, tromethamine)
  These control the viscosity and keep the formula from being too runny, ensuring it adheres well to the sheet and skin surface. 

• Humectants / Solvents (e.g. glycerin, butylene glycol, methyl gluceth‑20)
  These attract and hold moisture and provide a desirable texture to the formula, helping the actives penetrate while preventing extreme tackiness. 

• Preservatives / Skin‑Feel Enhancers (e.g. caprylyl glycol, ethylhexyl glycerin, 1,2‑hexanediol)
  These ensure the safety and shelf life of the formula while contributing to a pleasant skin feel. 

• Fragrance / Allergenic Components (e.g. limonene, linalool, citral)
  These are aromatic compounds derived from citrus or floral oils. While they enhance the sensory experience, they also carry a risk of irritation or sensitization in more reactive skin types. 

Product Experience & Texture

The sheet mask is crafted from a soft, breathable, dense-fiber material designed to lightly adhere to facial contours and settle into curves and lines to maximize contact and absorption. 

When applied, users may perceive a gentle tingling or cooling sensation—attributed to the Tingle-Pore Complex™ and its peppermint/menthol-derived extracts—intended to signal active ingredient delivery. 

After removing the mask (typically between 10 and 20 minutes of contact), the skin may feel hydrated, smooth, and subtly revitalized. Residual essence can be patted or massaged into the skin to allow complete absorption and maximize efficacy. 

Benefits & Claims

Based on its ingredient composition and marketing positioning, the mask aims to deliver the following skincare benefits:

1. Pore Refinement / Tightening
   The blend of botanicals (mint, rosemary, witch hazel) with active ferments is intended to visibly reduce the appearance of enlarged pores and help firm skin.

2. Softening & Texture Smoothing
   Bifida ferment lysate and galactomyces help reduce roughness, filling micro‑texture irregularities and promoting smoother skin. 

3. Hydration & Moisture Retention
   Ingredients like sodium hyaluronate, glycerin, panthenol, and squalane help increase the skin’s water content and prevent moisture loss, yielding a more supple, comfortable feel. 

4. Antioxidant & Soothing Support
   The ferment extracts and plant-based polyphenols (from green tea, rosemary, etc.) offer protective antioxidant benefits, helping defend against oxidative stress. The botanicals may also provide mild anti-inflammatory or calming effects. 

5. Brightening / Radiance
   Niacinamide, along with the ferment extracts, can assist in reducing dullness and uneven tone, promoting a more luminous complexion with regular use. 

6. Barrier Support & Skin Resilience
   The inclusion of lipid-compatible ingredients (like squalane) and ferment-derived peptides supports barrier resilience, reducing sensitivity and improving long-term texture health. 

Notably, the official product claims include passing a low-irritation test, suggesting that the formula is intended to be gentle enough even for skin types that are more reactive. 

Suggested Usage & Tips

Here’s how the product is recommended to be used (and how to get optimal results):

1. Cleanse & Tone
   Begin with a clean, freshly cleansed face. Use a mild cleanser, followed by a toner or essence (optional) to prep the skin and increase absorption.

2. Apply the Mask
   Unfold the sheet and align with facial features—start with the eye area, then smooth onto the rest of the face. Gently press it to ensure full contact with the skin.

3. Duration
   Leave the mask on for 10–20 minutes (some sources suggest up to 15–20 min). It is not recommended to leave it on until it fully dries, as that may draw moisture back out of the skin. 

4. Removal & Absorption
   Remove the mask and gently pat (or massage) any remaining essence into the skin until fully absorbed. This ensures the actives penetrate deeper rather than evaporating. 

5. Follow-Up Skincare
   Continue with subsequent steps in your skincare routine (serum, moisturizer, sunscreen). The mask primes the skin to accept further treatments.
   Use 2–3 times per week or as needed depending on your skin’s condition. 

6. Patch Test First
   Because the formula includes essential oils and fragrance compounds (limonene, linalool, citral), it’s wise for those with sensitive or reactive skin to perform a patch test first, applying the mask behind the ear or on a small section of the jawline to monitor for irritation.

Cautions & Considerations

• Sensation: The “tingling” effect is intentional and indicates the active blend working, but if the sensation escalates into stinging, burning, or discomfort, one should remove the mask immediately.

• Essential Oils / Fragrance: The formula contains citrus peel oils, lavender oil, and other aromatic compounds (with limonene, linalool, etc.), which may pose a risk of sensitization or irritation for reactive or fragrance-intolerant skin types.

• Duration Limit: Do not leave the mask on beyond recommended time. As the sheet begins to dry, it may draw moisture back out of the skin.

• Complementary Use: Avoid using alongside other strong actives (high-concentration acids, retinoids, physical scrubs) on the same evening, unless your skin is well accustomed to combinations.

• Storage & Handling: Keep in a cool, dry place, and use promptly after opening for best efficacy.

• Discontinue Use: If any rash, persistent redness, or discomfort arises, cease use and consult a dermatologist.

Comparative Observations & User Feedback

From user reports and reviews, a few patterns emerge:

• Many users appreciate the serum-rich packaging, noting there is often excess essence left in the pouch that can be reused on the neck, arms, or as extra hydration layers.

• The tingling sensation is commonly mentioned—some view it as evidence of potency and absorption; others caution that it may feel a little sensitive for those with delicate skin.

• Some report visible results such as tighter pores, smoother texture, and enhanced radiance when used consistently over time.

• On the flip side, a few users caution that results may not be dramatic overnight and that consistency, along with a supportive skincare regimen, is key to achieving noticeable benefits

• There is occasional mention in skincare communities of mild purging or sensation when first incorporating products with ferment or botanical actives—but such experiences vary widely between individuals.

Summary & Positioning

The Numbuzin No.3 Tingle‑Pore Softening Sheet Mask is a premium, multi-functional treatment that combines fermentation technology, botanical extracts, and proven skincare actives to deliver hydration, texture refinement, pore care, and a luminous finish in a sheet mask format. Its signature “tingle” effect is a sensory indicator intended to convey active penetration. While the mask is designed with ingredients supportive of skin health—even for drier or aging skin types—it contains botanical aromatics and fragrance-derived compounds that may not suit all skin types, especially very sensitive or fragrance-intolerant skin.

For users looking to enhance their texture, blur pore visibility, and boost hydration in a single, pampering step, this sheet mask offers a powerful and concentrated delivery system. When used as part of a balanced routine (with gentle cleansing, sun protection, and barrier-supportive products), it can serve as an effective weekly or semi-weekly treatment to maintain a smoother, more radiant complexion.
