What is an Overnight Mask in K-Beauty?
An overnight mask, also known as a sleeping pack in K-beauty, is a deeply hydrating and reparative treatment designed to be applied as the final step of your evening skincare routine. Unlike rinse-off masks, overnight masks work while you sleep—capitalising on the skin’s natural nighttime regeneration process to deliver targeted ingredients for enhanced results by morning.

How It Works – The Science Behind It
Your skin enters repair mode while you sleep, with increased cell regeneration and moisture loss. Medicube’s Overnight Mask contains a high concentration of low molecular weight hyaluronic acid, which penetrates deeply to deliver hydration at multiple skin levels. The inclusion of peptides and niacinamide works to improve skin tone and elasticity, while Centella Asiatica extract soothes inflammation and strengthens the skin barrier.
