Modern lifestyles often involve late nights and irregular sleep patterns, which reduces the skin’s ability to repair itself at night. Sleeping masks are skincare products that work specifically during the night. So, what exactly are the functions of sleeping masks? Are they truly effective? Are they suitable for everyone? They differ significantly in terms of usage, focus on efficacy, and product texture. They are not interchangeable, but rather skincare steps designed for different needs.

Deep hydration at night
Sleeping masks actively capture and store moisture, continuously delivering it to the stratum corneum, and even attracting moisture from the environment to the skin, thus maintaining the hydration of the stratum corneum for an extended period.
Other auxiliary repair ingredients:
- Squalane: A lipid very similar to human sebum, with excellent skin compatibility, it softens the stratum corneum and replenishes the skin’s lipid barrier.
- Panthenol (Vitamin B5): Provides powerful hydration, promotes epithelial cell repair, and soothes irritation.
- Ectoin, Bisabolol, Centella Asiatica Extract, etc.: Possess strong anti-inflammatory and soothing effects, relieving inflammatory reactions caused by a damaged skin barrier.
- Natural moisturizing factors: Such as urea and lactic acid, help keratinocytes maintain moisture.
