Hada Labo Gokujyun Premium Hyaluronic Acid Lotion Toner

Hada Labo Gokujyun Premium Hyaluronic Acid Lotion 170ml is an intensive hydrating toner for very dry, mature, or persistently dehydrated skin that does not respond adequately to the standard Gokujyun formula. Where the standard toner uses 4 types of hyaluronic acid, this Premium version uses 8 — including fermented Hyaluronic Acid and the smallest-molecular Nano Hyaluronic Acid — plus Sacran, an algae-derived ingredient that holds 5 times more moisture than standard HA and forms a sustained hydration film on the skin surface.

• 8 types of Hyaluronic Acid including fermented HA and Nano HA — penetrates deeper and retains longer than standard formulas
• Sacran (Suizenji Nori Algae) — rare Japanese botanical that forms a moisture-sealing film on the skin surface
• Hydroxyethyl Urea — softens the outer skin layer to improve absorption of subsequent products
• Noticeably thicker, more viscous texture than the standard Gokujyun toner
• Fragrance-free, alcohol-free, colorant-free — suitable for sensitive and eczema-prone skin
• 170ml — full-size; a small amount goes further than the standard version due to concentration

How it works: The 8-HA system targets different skin layers simultaneously: large-molecule HA forms a surface film, mid-size HA works in the outer stratum corneum, and Nano HA penetrates further. Fermented HA mimics the skin's own moisture-binding process. Sacran then seals all that hydration in from the surface, creating a compounding effect that lasts into the next day.

Premium vs standard Gokujyun: The standard Gokujyun toner (blue label) is appropriate for normal to mildly dry skin. This Premium (gold label) is for skin that feels tight, rough, or flaky despite using the standard version, or for mature skin in its 40s and beyond where natural moisture-retention declines.

Known in Japan as 肌ラボ 極潤プレミアム ヒアルロン液 170ml.
