Sulwhasoo Overnight Vitalizing Mask 120ml

Apply as your last nighttime step and leave on overnight.

Sleeping masks are useful because skin loses water overnight and spends several hours without daytime environmental interruptions. A leave-on mask can create a more sustained moisture environment than a rinse-off treatment, helping soften rough texture and reduce the tight, fatigued feel that often shows up by morning. Products in this category typically rely on humectants to draw in water and emollients to reduce moisture loss while you sleep. That combination helps the skin surface feel smoother and look more rested when you wake up. Because the formula is positioned around visible vitality, its main role is not aggressive resurfacing but overnight replenishment and comfort support. This kind of mask can also make the complexion appear fresher simply by improving hydration balance, which affects both texture and light reflection. In practical use, an overnight mask is best for people who want an easy final step that supports softness, suppleness, and a more revitalized morning appearance.
