Key Ingredients

SLEEP-TOX™(スリープトックス)
Blend of Evening Primrose, Hawthorn, and Lily extracts. Balances skin hydration during sleep and reduces oxidative stress.
ヒアルロン酸(低分子)
Low-molecular HA with excellent stratum corneum penetration. Deep hydration preventing dryness until morning.

How It Works

During sleep, TEWL increases with stratum corneum hydration lowest at 2-4 AM. The gel texture forms a moisture-retaining film that physically suppresses TEWL. Low-MW HA penetrates to maintain hydration. SLEEP-TOX™ antioxidants reduce oxidative stress accumulated during sleep, supporting normal cell turnover. Ionized minerals from mineral water draw moisture into the stratum corneum via osmotic pressure.

How to Use

As final step of nighttime skincare, apply a thin even layer over entire face (no thick application needed). Sleep overnight and rinse off in morning. Recommended 2-3 times per week (daily use also acceptable).

Expected Results

Immediate next-morning plumping and glow. Regular use over 2-4 weeks stabilizes skin hydration, improving dryness-related dullness and fine lines. Better makeup application.

Precautions

Oily/acne-prone skin: limit to 1-2x weekly. If pillow transfer is a concern, let dry 10 minutes before sleeping. If pilling occurs, ensure previous skincare has fully absorbed before applying.
