Round Lab Birch Juice Moisturizing Mask - Sheet Mask Set 25ml

Round Lab’s Birch Juice Moisturizing Mask arrives pre-dosed at 25ml per sheet, delivering a concentrated hydration layer designed to replenish skin without excess drip or wasted serum.

Each piece in this set uses birch juice as the foundational ingredient. The botanical extract binds water molecules to the outer epidermis, reducing transepidermal water loss during application. Because the liquid volume is fixed at 25ml, treatment sessions remain predictable, eliminating the need to balance dilution ratios or estimate leftover product.

How the Sheet Format Delivers Results

Place the saturated mask over cleansed skin to establish a closed environment that extends contact time. This physical barrier slows evaporation and directs the birch juice concentrate inward rather than allowing it to sit on the surface. After removal, lightly press any remaining essence into the tissue so it locks in without needing additional emollients.

• Fixed 25ml capacity provides accurate dosing for monthly tracking or spot treatment
• Birch juice composition prioritizes moisture retention over heavy masking formulas
• Pre-fitted sheet geometry aligns with standard facial landmarks for even distribution

Integrate this Round Lab Birch Juice Moisturizing Mask set into your regimen by applying the sheet after cleansing and before thicker creams or oils. Keep unused packets sealed away from direct sunlight to maintain serum consistency and protect the extract until the next cycle.
