Hada Labo Gokujyun Medicated Aging Care Lotion 170ml

Hada Labo Gokujyun Aging Care Medicated Lotion 170ml is a quasi-drug certified toner for mature and dry skin showing early signs of dryness-related aging: fine lines, loss of firmness, and rough texture that worsens with seasonal dryness. It combines Niacinamide — a medicinal active with clinical evidence for improving skin elasticity and reducing the appearance of wrinkles caused by dryness — with multiple types of Hyaluronic Acid for deep hydration.

• Niacinamide — quasi-drug certified active for improving skin elasticity and reducing dryness-related fine lines
• Multiple types of Hyaluronic Acid — deep multi-layer hydration to plump the skin and reduce the visibility of dehydration lines
• Fragrance-free, alcohol-free, colorant-free — formulated for mature and sensitive skin
• 170ml full-size — standard pharmacy size
• Suitable as a morning and evening toner step for skin in its 30s, 40s, and beyond

How it works: Niacinamide (Vitamin B3) at medicinal concentration improves the skin's ceramide synthesis — increasing the skin barrier's ability to retain moisture. This addresses the structural cause of dryness-related aging rather than only adding surface hydration. The HA system then builds additional moisture density on top of the improved barrier.

Aging Care Medicated Toner vs standard Gokujyun Toner: The standard Gokujyun toner hydrates without anti-aging actives — appropriate for younger skin focused on moisture maintenance. This Aging Care version adds Niacinamide as a medicinal active targeting skin firmness and wrinkle appearance — appropriate for skin that has started showing dryness-related lines or where hydration alone is no longer sufficient.

Known in Japan as 肌ラボ 極潤 薬用ハリ化粧水 170mL.
