Product Info

The hydration of a sheet mask in a serum: Icelandic glacier water and five types of hyaluronic acid for skin that wakes up plump, soft and glowing.

Numbuzin's No.6 line is dedicated to hydration, and this serum is designed to give you the moisture boost of a sheet mask without the sheet. It replaces purified water with 63% Icelandic glacier water and layers in five types of hyaluronic acid, niacinamide and panthenol. The watery texture absorbs quickly and leaves a non-sticky, dewy finish — perfect as a night-time final step or on days when skin feels tight.

✨ Why You'll Love It

  • 63% Icelandic Glacier Water – A mineral-rich base in place of purified water
  • 5 Types of Hyaluronic Acid – Hydrate at different levels for plump, bouncy-looking skin
  • Niacinamide – Helps brighten and even out a dull complexion
  • Panthenol & Dipotassium Glycyrrhizate – Soothe and comfort dry, tight skin
  • Sheet-Mask Hydration – A watery, non-sticky serum that delivers mask-level moisture every day

Ideal for dry, dehydrated or dull skin that needs a deep drink of moisture overnight.

💚 Clean & Conscious Beauty

  • Suitable for: All skin types, especially dry, dull and dehydrated skin

How to Use: After toner, apply a generous amount to the face and pat gently until absorbed. Use as a final hydrating step at night, or morning and evening under moisturiser when skin feels dry.
