Product
Overview

numbuzin No.6 Deep Sleep Mask Serum (50ml) is an innovative hybrid
product from numbuzin’s No.6 Sleep line — a product category that combines
the concentrated active delivery of a serum with the occlusive,
overnight-sealing function of a sleeping mask for a uniquely comprehensive
overnight treatment that works more intensively than either a standalone
serum or standalone sleeping mask could achieve individually. The Deep Sleep
Mask Serum is designed to be used as the final nighttime routine step,
applied after all toners, serums, and moisturisers, where it seals the entire
accumulated routine underneath a breathable protective layer that maintains
the underlying products in sustained skin contact throughout the full sleep
period.

The concept of “deep sleep” skincare is grounded in
well-established circadian skin biology: the skin’s cellular repair and
regeneration activity peaks during the deep sleep phases of the sleep cycle
(approximately between midnight and 4am), driven by the peak of growth
hormone secretion and melatonin-mediated antioxidant activity during sleep.
During this window, the skin’s ability to absorb and utilise active
ingredients is maximised — cell turnover is accelerated, collagen synthesis
is at its daily peak, and inflammatory responses are modulated downward. By
positioning itself as the final “deep sleep” treatment step,
numbuzin’s Mask Serum ensures that its actives and moisture-sealing effect
are working in concert with the skin’s own peak repair activity for the
deepest possible overnight treatment. The serum-level active concentration
within the mask means that the product contributes meaningful active
ingredients beyond simply sealing underlying products, making it a genuine
overnight treatment rather than a purely occlusive layer.

Key Benefits

Hybrid mask-serum combines concentrated serum actives with
sleeping mask’s moisture-sealing occlusive function.
Works synergistically with the skin’s peak nocturnal repair
activity during deep sleep for maximum overnight efficacy.
Seals entire underlying routine in sustained skin contact
throughout the sleep period for amplified routine efficacy.
Serum-level active concentration ensures meaningful ingredient
delivery beyond a purely occlusive mask layer.
Wake up to visibly more hydrated, plumped, and renewed skin after
consistent overnight deep sleep mask treatment.

Key Ingredients

Overnight Repair Complex: a blend of skin renewal actives
(peptides, antioxidants, or regeneration actives — check packaging for
specifics) that deliver targeted treatment during the overnight period.
Moisture Sealing Actives: film-forming agents, occlusives, and humectants
that create the sleeping mask seal for sustained overnight skin contact. Skin
Renewal Actives: ingredients supporting the skin’s own nocturnal regeneration
processes during the deep sleep window.

Who It’s For

Ideal for all skin types wanting an intensive overnight treatment
that goes beyond a basic sleeping mask by combining serum-level active
delivery with moisture sealing for a comprehensively effective deep sleep
skincare step. Particularly suited to those who want to maximise their
nighttime routine efficacy with an advanced final-step product. Use 3-5 times
weekly for intensive treatment or nightly as a continuous overnight treatment
step.
