Transform your daily hydrating step into an advanced clinical deep-hydration, barrier-rehabilitating, and skin-cooling ritual. Immediately after cleansing and toning, your skin is highly vulnerable. Without an immediate moisture-replenishing layer, vital water begins to evaporate rapidly into the dry air—a process known as trans-epidermal water loss (TEWL). This sudden moisture drain causes epidermal cells to shrink and harden, forming a rough, rigid surface layer of dead skin cells that leads to immediate tightness, flakiness, and a dull, sallow complexion. Traditional thick serums often fail to resolve this chronic condition, as their large molecular sizes prevent them from penetrating deep beneath the surface. The ROUND LAB Birch Juice Moisturizing Ampoule 50ml systematically solves this dilemma.

Formulated to perfectly respect sensitive, parched, and easily flushed skin profiles, this premium ampoule operates as a highly concentrated, deep-penetrating moisture pump. It is powered by Silver Birch Sap (10,000ppm) 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 incorporates Glyceryl Glucoside to activate "aquaporins"—the microscopic water channels within your cells—allowing hydration to flow freely throughout your skin tracks. Working in harmony with a multi-layered Hyaluronic Acid matrix and a soothing complex of Panthenol and Allantoin, it seals in core moisture and dampens redness, converting a parched, tight, or tired face into an exceptionally uniform, bouncy, and flawlessly prepped water-glow canvas.

  • Inje Silver Birch Sap Infusion: Satiates parched, tired skin cells 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.
  • Deep-Layer Hyaluronic Hydration: Employs multiple molecular weights of Hyaluronic Acid to plump dehydrated cells from the inside out, eliminating inner tightness and dry patches.
  • Barrier-Safe Soothing Lock: Saturated with Panthenol and Allantoin to protect raw skin, calm environmental friction, and reinforce the protective moisture barrier.

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.
  • Multi-Hyaluronic Acid Matrix: Distinct molecular weights of hyaluronic acid that deeply penetrate dry dermal tracks, plumping cells with weightless water and locking it inside.
  • Panthenol & Allantoin: A powerful soothing and skin-conditioning duo that protects raw skin, calms physical skin stress, and reinforces the protective moisture barrier.

  • Step 1: Use daily during your morning (AM) and evening (PM) skincare routines. Apply immediately after your daily cleansing and toning steps, before your final moisturizer or cream.
  • Step 2: Use the dropper to dispense 2 to 3 drops of the ampoule directly onto your forehead, cheeks, and chin, or into clean palms.
  • Step 3: Smooth the fluid gel evenly across your face and neck, moving gently outward along your skin's natural contours. Focus extra attention on dry-prone zones.
  • Step 4: Lightly pat with your fingertips to encourage complete, instantaneous absorption. Follow up with your favorite daily sunscreen in the morning.

✨ The Ultimate "Hydration-Sandwich Plumping" Pro-Tip: On days when your skin feels exceptionally raw, wind-burned, or when you notice dry patches that make your daily foundation or cushion separate, try the professional "double-locking" layering method.

After applying your first layer of hydrating toner, apply a generous layer of the Birch Ampoule over your entire face and pat it in lightly. Let it absorb for 30 seconds.

Then, take another 1 to 2 drops of the ampoule and press it specifically onto your primary dehydration zones—such as your cheeks, forehead, and around the mouth. Immediately follow up with your daily moisturizer or cream while your face is still slightly damp.

This technique creates a highly breathable, multi-layered moisture barrier that traps the active Birch Sap, Glyceryl Glucoside, and Hyaluronic Acid molecules directly within your skin's natural lipid tracks, completely blocking trans-epidermal water loss. You will reveal an incredibly smooth, plumped, and exceptionally resilient glass-skin canvas that lasts all day long!
