This is a leave-in sleeping mask focusing on intensive night repair. It utilizes the golden period of skin self-repair at night to continuously deliver nutrients and moisture to the skin, achieving the skincare effect of "better skin after a night's sleep". The formula adopts a highly moisturizing hyaluronic acid compound system, paired with squalane and ceramides to form a water-locking protective film on the skin surface, continuously hydrating all night and improving dryness, roughness and fine lines. At the same time, bifida ferment lysate, vitamin E and peptides are added to repair daytime light damage and oxidative damage, improve dullness, yellowing and fatigue caused by staying up late, leaving the skin bright and plump the next morning. The product has an elastic sorbet texture, hydrating and refreshing after spreading, non-greasy and does not stick to pillows. No rinsing required, apply a thin layer as the last step of evening skincare before going to bed. Fragrance-free gentle formula, suitable for most skin types. Especially suitable for people with busy work and little skincare time, as well as intensive night care for tired and dry skin from staying up late.
