numbuzin No.6 Deep Sleep Mask Serum 50ml

Features

The numbuzin No.6 Deep Sleep Mask Serum is formulated to provide intensive hydration and relief for thirsty, dehydrated skin. Designed to act like a moisture mask pack, this serum helps combat inner dryness, flaking dead skin cells, and easily heated skin. It delivers deep moisturizing benefits down to 2.5mm and ensures long-lasting hydration for up to 48 hours. The formula functions as a dual functional cosmetic for whitening and wrinkle improvement, suitable for all skin types.

Benefits

This serum provides a rapid moisture boost to rough and parched skin from the very first application, helping to relieve skin thirst and dryness. When applied before bed, it can be layered multiple times to act as a sleeping mask, leaving the skin looking vibrant and well-rested as if after a deep sleep. It helps smooth out flaky dead skin cells around areas like the brows and builds a moisture-rich glow that lasts throughout the day.

Main Ingredients and their effects

Glacier Water: Sourced from Iceland and rich in minerals, it delivers intensive moisture and hydration replenishment to dry skin.

5-Layers of Hyaluronic Acid: A combination of high molecular, low molecular, and ultra-low molecular hyaluronic acid components (including Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hydrolyzed Glycosaminoglycans, and Hyaluronic Acid) that form moisture barriers on the surface and supply deep hydration down to the inner layers of the skin.

Panthenol: Works alongside moisturizing factors to attract and retain moisture, effectively targeting inner dryness and creating a radiant moisture glow.

Clinical test results

Clinical testing conducted by the P&K Skin Research Center on adult women aged 30 to 59 demonstrated a 17.8% improvement in skin deep moisturizing power immediately after a single use. Testing also confirmed the maintenance of deep skin moisturization for up to 48 hours across various skin depths.

Usage instructions

For daily care, apply an appropriate amount to the skin after cleansing to deliver immediate moisture to rough and dehydrated skin. For special care, layer the product multiple times before going to bed to use it as a 48-hour sleeping mask for a well-rested and vibrant complexion.
