ROUND LAB Birch Juice Moisturizing Sheet Mask (10 Sheets) is a high-performance, deeply hydrating daily sheet mask treatment engineered to instantly quench severe inner dryness, lower skin surface temperature, and lock in core hydration. Saturated with mineral-rich Inje Silver Birch Sap, aquaporin-activating Glyceryl Glucoside, and a multi-layered Hyaluronic Acid matrix, this premium water-retaining sheet conforms flawlessly to every facial contour. It melts past surface resistance to flood dehydrated cellular pathways, preventing rapid trans-epidermal water loss (TEWL) and leaving a parched, flushed, or sensitive canvas remarkably plumped, perfectly calm, and glowing with a fresh, dewy glass-skin finish.

  • Target Concerns: Severe Dehydration & Inner Tightness, Solar Thermal Heat & Flushed Skin, Rough & Flaky Skin Texture, Weakened Moisture Barrier, Dull & Fatigued Complexion
  • Skin Compatibility: All skin types (Highly optimized for dry, dehydrated, combination, and sensitive skin profiles requiring an immediate, non-sticky burst of deep moisture and cooling relief)
  • Texture & Finish: An ultra-adherent, eco-friendly cotton sheet saturated in a light, refreshing water-gel essence that wraps the face in a comforting moisture cushion, cooling the skin on contact and absorbing cleanly to leave a plumped, velvety-soft, and residue-free satin baseline.

Transform your weekly deep-hydration and skin-calming steps into an advanced clinical cell-plumping, barrier-rebuilding, and thermal-cooling ritual. Immediately after cleansing, or when exposed to harsh environmental factors, the skin's surface temperature can spike, triggering a rapid moisture drain known as trans-epidermal water loss (TEWL). As vital water quickly evaporates into the dry air, epidermal cells shrink and harden, forming a rough, rigid surface layer of dead skin cells. This cellular stress leads to immediate tightness, flaky patches, and a dull, sallow complexion. Traditional sheet masks often fail to resolve this, as their rough paper fibers can create physical friction on a raw barrier, and their watery essences evaporate too quickly. The ROUND LAB Birch Juice Moisturizing Sheet Mask systematically solves this dilemma.

Formulated to perfectly respect sensitive and parched epidermal ecosystems, this premium mask utilizes a bio-compatible, high-adherence sheet designed to hold an extraordinary volume of active hydrating essence. It clings seamlessly to every curve of the face like a second skin, providing a continuous, slow-release delivery of nutrients without drying out or pulling moisture back from the skin. It is powered by Silver Birch Sap harvested from the pristine, high-altitude microclimates of Inje, which is packed with amino acids, vitamins, and natural minerals that mimic the skin's natural moisturizing factors (NMF). To ensure deep-level delivery, it features Glyceryl Glucoside to activate "aquaporins"—the microscopic water channels within your cells—allowing clean moisture to flow freely throughout your epidermal tracks. It converts an overheated, tight, or tired face into an exceptionally uniform, bouncy, and flawlessly polished water-glow canvas.

  • Inje Silver Birch Sap Infusion: Satiates parched skin with vital amino acids, vitamins, and minerals to deeply nourish, calm, and restore natural skin radiance.
  • Aquaporin-Activating Hydration: Powered by Glyceryl Glucoside to open the skin's internal water channels, ensuring continuous, deep-layer moisture flow.
  • Instant Thermal Cooling: Drops skin surface temperature upon contact, rapidly calming solar-induced redness and soothing active skin irritation.
  • High-Adherence Water-Gel Lock: Employs a premium cotton-gel sheet that forms an airtight, highly breathable barrier, preventing moisture evaporation and leaving dry zones fully plumped.

Key Ingredients

  • Betula Platyphylla Japonica Juice (Birch Sap 10,000ppm): A nutrient-dense botanical extract rich in minerals and amino acids that deeply nourishes, calms, and revitalizes a tired complexion.
  • Glyceryl Glucoside: A specialized active derived from resurrection plants that stimulates aquaporins, the skin's natural moisture channels, to deliver intense inner hydration.
  • Sodium Hyaluronate: A bio-compatible hyaluronic acid that deeply penetrates dry dermal pathways to instantly plump cells with weightless water.
  • Panthenol & Allantoin: A powerful soothing and skin-conditioning duo that protects raw skin, calms physical friction, and reinforces the protective moisture barrier.

  • Step 1: Use 2 to 3 times a week during your evening (PM) skincare routine, immediately after your daily cleansing and toning steps.
  • Step 2: Open the pouch, retrieve the sheet mask, and carefully unfold it.
  • Step 3: Apply the mask evenly over your face, aligning it carefully with your eyes, nose, and mouth to ensure a snug, seamless fit.
  • Step 4: Leave the mask on for 10 to 20 minutes. Remove the mask and gently pat the remaining essence into your face and neck with clean fingertips until fully absorbed. Follow up immediately with your daily moisturizer.

✨ The Ultimate "Double-Cooling Aquaporin" Prep Pro-Tip: On days when your skin is experiencing a sudden sensitive flare-up, intense wind-burn, or extreme localized heat under the sun, transform this sheet mask into an emergency cooling compress.

Keep your sheet mask in the refrigerator for 15 to 20 minutes before application. Once chilled, apply the mask to your face. The cold temperature works instantly to constrict blood vessels and drop skin heat, reducing puffiness and immediately calming flushed skin.

While the sheet is on your face, take any excess cooling essence remaining inside the pouch and gently pat it over your neck, chest, and the backs of your hands.

After removing the sheet, pat the remaining nutrients in. This locks the active Birch Sap and hyaluronic acid molecules directly into your skin's natural lipid tracks, completely blocking moisture evaporation. You will wake up to an incredibly calm, smooth, and flawlessly plumped glass-skin baseline!
