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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAging Care Medicated Toner vs standard Gokujyun Toner:\u003c\/strong\u003e 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.\u003c\/p\u003e\u003cp\u003eKnown in Japan as 肌ラボ 極潤 薬用ハリ化粧水 170mL.\u003c\/p\u003e","brand":"Hada Labo","offers":[{"title":"Default Title","offer_id":47486297080061,"sku":null,"price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/7556\/8893\/files\/hada-labo-gokujyun-medicated-aging-care-lotion-170ml.png?v=1777813559","url":"https:\/\/tokyoshelf.com\/products\/hada-labo-gokujyun-medicated-aging-care-lotion-170ml","provider":"Tokyo Shelf","version":"1.0","type":"link"}
