Your beauty sleep in a bottle: Numbuzin No.6 Serum
Imagine waking up every morning with plump, radiant and deeply moisturized skin. The Numbuzin No. 6 Deep Sleep Mask Serum makes this dream come true! This innovative night serum acts like an intensive moisturizing mask while you sleep. It revitalizes tired, thirsty skin, replenishes moisture stores and forms a protective barrier so you start the day with a refreshed and rested complexion.
The power of ingredients: glacier water meets hyaluronic acid
The formula is a true moisturizing cocktail that nourishes and repairs your skin from the inside out overnight.
- Icelandic glacier water (63%): Instead of regular water, this serum uses pure, mineral-rich glacier water. It provides instant, cool refreshment and pure moisture.
- 5-species hyaluronic acid complex: Different molecule sizes of hyaluronic acid penetrate into different layers of the skin. The result: intensive, long-lasting hydration from the surface to the depths.
- Niacinamide: While you sleep, this miracle ingredient works to strengthen your skin barrier, even out skin tone and brighten skin.
- Panthenol (provitamin B5): Soothes the skin, relieves redness and supports the skin's own regeneration process overnight.
How to integrate the serum into your routine
- Apply the serum as the last step of your evening skincare routine.
- Take an appropriate amount and gently spread it over your face.
- Pat the product in gently and let it work its magic overnight.
Pro tip: On particularly dry days or when your skin needs an extra dose of care, you can also apply the serum on top of your normal night cream. This will effectively lock in all the moisture and active ingredients.
Complete your routine with Numbuzin
Incorporate the Deep Sleep Mask Serum into a comprehensive Numbuzin routine to optimally nourish your skin.
- Step 1 (Toner): numbuzin No.4 Pore zero peeled egg toner pad - Start your routine with these pads to gently exfoliate the skin and make it receptive for subsequent care.
- Step 2 (Treatment): Numbuzin No.3 Skin Serum (Skin Softening) - Apply this serum before the sleeping mask to work on the skin's texture and ensure ultimately smooth skin.
Still have questions? We have the answers
Does this serum replace my night cream?
For oily to normal skin types, this serum can absolutely suffice as your sole night cream. If you have very dry skin, you can either use it instead of your cream or apply it on top for an extra moisturizing boost.
Is the serum suitable for sensitive skin?
Yes, the formula is rich in soothing ingredients such as panthenol and hyaluronic acid and free from many common irritants. It is designed to strengthen the skin barrier, making it ideal for sensitive skin.

"Ich habe das Numbuzin No.6 Deep Sleep Mask Serum in meine Abendroutine integriert, indem ich einfach ein paar Tropfen auf mein gereinigtes Gesicht aufgetragen habe. Besonders aufgefallen ist mir die leichte, wässrige Textur, die schnell einzieht und keinen klebrigen Film hinterlässt. Nach ein paar Anwendungen habe ich bemerkt, dass meine Haut deutlich frischer aussieht und sich gut mit Feuchtigkeit versorgt anfühlt, was mir ein angenehmes Gefühl gibt. Ich würde das Serum auf jeden Fall weiterempfehlen, vor allem für diejenigen, die eine einfache und effektive Lösung für eine müde Haut suchen."
