No.6 Deep Sleep Mask Serum 50ml

This is a serum that doesn't dry down, designed to work as both a treatment step and an overnight mask. It contains hyaluronic acid to hold moisture and niacinamide to calm irritation. Use it under your night cream or alone as your final step.

After toner and essence, apply a generous layer to clean skin. You'll feel the difference by morning — skin will be more plump and refreshed than when you started.
