No.6 Deep Sleep Mask Serum 50ml

Sleep through the night while your skin does all the heavy lifting with this serum-mask hybrid.

Why You'll Love It

• It's basically a serum that doesn't dry down — perfect for our humid Singapore nights without feeling sticky
• Wake up to plumper, more refreshed skin (no more dull, dehydrated mornings)
• Works as both a treatment step AND an overnight mask, so it earns its place in your routine
• Numbuzin's renewal line is all about gentle, consistent results — not shock-your-skin intensity

Key Ingredients

• Hyaluronic Acid — locks in moisture and keeps your skin plump through the night
• Niacinamide — calms irritation and strengthens your skin barrier (essential in Singapore's heat and humidity)

How to Use

After toner and essence, apply a generous layer to clean skin. Use as a treatment serum under your night cream, or skip the cream and let this be your overnight mask. You'll feel the difference by morning.

Step 2 in the Treat phase — this is where the real restoration happens.
