ROUND LAB Birch Moisturizing Sheet Mask (10ea) — Lightweight, Unscented Hydration with Inje Birch Sap

ROUND LAB Birch Moisturizing Sheet Mask is a lightweight, cooling sheet mask that delivers immediate hydration and calming moisture to dry, sensitive skin.

This 10-pack of single-use sheet masks combines Inje birch sap and a high proportion of botanical extracts in a watery, unscented base to refresh, soothe, and replenish skin quickly. The formula is designed to offer a cooling, non-sticky finish and avoids chemical additives, making it suitable for those who want a simple, gentle boost of moisture between treatments or after environmental stress.

What key ingredients hydrate and calm the skin?

The mask blends Inje birch sap, which helps support skin moisture, with concentrated plant extracts that focus on soothing and replenishing the skin barrier. A watery hyaluronic-type component helps lock in moisture for a plumper feel without heaviness.

• Inje birch sap for lightweight hydration and mineral support
• High-percentage botanical extract mix to calm redness and irritation
• Hyaluronic-like humectants to attract and retain moisture
• Unscented, low-irritant base suitable for sensitive skin

How quickly will I see results after one application?

Results are immediate in terms of surface hydration and a cooling sensation; skin looks visibly more refreshed and feels softer right away. For lasting improvement in comfort and texture, use regularly alongside your daily skincare routine.

• 10–15 minute wear time for instant moisture and a dewy finish
• Non-greasy, lightweight aftermath suitable under makeup
• Visible reduction in tightness and dryness after first use
• Best when used 1–3 times per week as a maintenance step

Is this mask appropriate for sensitive or reactive skin?

The formula is unscented and avoids harsh chemical additives, which reduces common irritants; however, always patch-test if you have highly reactive skin. The high botanical extract content is chosen for calming benefits, not aggressive exfoliation.

• Unscented, minimal-irritant formulation
• Sits lightly on skin to minimize friction and stress
• Designed for immediate soothing after exposure or cleansing
• Patch-test advised for very allergy-prone skin

How do I use the sheet mask for best effect?

After cleansing and toning, apply the sheet mask evenly across the face and relax for 10–15 minutes. Gently pat remaining essence into the skin after removing the sheet; no rinsing required.

• Cleanse and tone skin first for better absorption
• Leave on 10–15 minutes; avoid sleeping in the sheet
• Pat in leftover essence; follow with moisturizer if desired
• Use 1–3 times weekly or as a quick hydration pick-me-up

Who is this for: This mask suits anyone with dry, dehydrated, or sensitized skin looking for a fast, cooling hydration boost without heavy textures or fragrances. It's ideal for travelers, urban dwellers exposed to environmental stressors, or anyone wanting a gentle weekly treatment to maintain skin comfort and suppleness.
