Description

NUMBUZIN No.6 Deep Sleep Mask Serum gives your skin a drink of moisture while you sleep. This lightweight overnight mask feels like a soft hug for tired skin. Made with glacial water and five types of hyaluronic acid, it helps skin stay hydrated for up to 48 hours. The gentle formula brightens, soothes, and firms without feeling heavy or sticky. Perfect for all skin types that need a boost of moisture and glow, this mask works its magic overnight so you wake up to soft, happy skin. It's the simple way to help your skin look its best while you rest.

A Drink of Moisture While You Sleep

When your skin feels dry, tight, or looks a bit dull, it's asking for help. NUMBUZIN No.6 Deep Sleep Mask Serum steps in as your skin's best friend at night. With 63% glacial water rich in good minerals, this mask serum gives deep moisture that lasts. Think of it as a tall glass of water for thirsty skin.

The magic happens while you sleep. Just smooth a layer on as the last step in your night routine. The light, non-sticky feel sinks right in without mess on your pillow. By morning, skin feels soft, looks bright, and feels happy. It's that simple – sleep and let the mask do the work.

Kind Ingredients That Love Your Skin

We believe skincare should be gentle and good for you. That's why this mask serum brings together ingredients that truly help:

  • Glacial water: Packed with minerals that wake up tired skin
  • Five types of hyaluronic acid: Pulls moisture deep into skin where it's needed most
  • Niacinamide: Helps even out skin tone and brighten
  • Panthenol: Calms and soothes any redness
  • Turmeric root extract: Helps skin look clear and fresh
  • Adenosine: Helps skin feel firm and smooth

Free from parabens and artificial colors, this formula works with your skin, not against it. The light, natural scent comes from plant extracts – no fake fragrances here.

For Every Skin Story

Dry skin drinks it up. Oily skin (that's still thirsty) loves how light it feels. Even sensitive skin can find comfort here. This mask works for all skin types and all ages – from your 20s onward.

It's best in dry months when heating or air conditioning pulls moisture from your skin. But truth be told, it works year-round for anyone wanting more glow and less dryness. The mask helps with common concerns like:

  • Dry, tight feeling skin
  • Morning dullness
  • Uneven tone
  • Fine lines from dryness
  • Rough texture

How to Make It Part of Your Night

Using this mask serum is as easy as can be. After washing your face and using any toners or serums you love:

  • Pump 2-3 drops onto your fingertips
  • Gently press into your skin, don't rub hard
  • Cover your whole face with a thin layer
  • For extra dry spots, add a tiny bit more
  • Let it sink in for a moment before your head hits the pillow

No need to wash off in the morning – just wake up and go on with your day. Use it every night for best results, or a few times a week when your skin needs extra love.

Wake Up to Happy Skin

The first morning after using NUMBUZIN No.6, you'll notice skin feels softer right away. Many people say their skin feels about 17% more hydrated after just one night. But the real magic builds over time.

With regular use, you'll see:

  • Skin that stays moist all day
  • A natural glow that comes from within
  • Smoother, more even texture
  • Less visible fine lines from dryness
  • A calm, happy look to your skin

This mask doesn't make big promises it can't keep. Instead, it gives real results you can see and feel – the kind that make you smile when you look in the mirror each morning.

Give your skin the gentle care it deserves tonight. Add NUMBUZIN No.6 Deep Sleep Mask Serum to your evening routine and wake up to the soft, glowing skin you love. Your skin will thank you with every morning smile!

How to Use

After cleansing and toning, dispense 2-3 pumps of the serum onto your fingertips. Gently apply evenly over your face as the final step of your evening skincare routine. Pat or tap lightly to enhance absorption. For optimal hydration, you may apply a second layer if desired. Use daily overnight for best results in deep hydration and skin rejuvenation.

Store in a cool, dry place away from direct sunlight. Keep the cap tightly closed to preserve product integrity. With regular use, a 50ml bottle typically lasts about 1 to 1.5 months, depending on application amount. Suitable for adult skin from early 20s onward, especially beneficial for dehydrated, dull, or aging skin. Incorporate into your routine after cleansing and toning, before moisturizer or sleeping mask, and avoid heavy occlusive products that could hinder absorption. Ideal for use in cooler or dry seasons but versatile enough for year-round hydration needs.

  • Skin that feels dry or dehydrated by evening
  • Anyone wanting a light, non-sticky night serum
  • Those who like a sleep-mask step without a heavy cream
  • Skin that looks dull and could use a dewy, plump finish
Worried the slip meant it was oil-based

Initially the texture was slightly weird. I thought it was oil based because it felt so slippery but it’s not and it settles down onto my skin nightly leaving it plump and bouncy to the touch. … No breakout, no purging, no irritation. Just nice, everything just nice about this serum.

Hyaluronic-acid serums can feel slippery from humectants rather than oil — that initial slip doesn't mean a formula is oil-based.

Wake to skin that feels rested and dewy.
