IHADA Medicated Moist Lotion Very Moist 180ml is a quasi-drug toner for sensitive and atopic dry skin that repeatedly breaks out or becomes rough despite regular moisturising — using Allantoin and Dipotassium Glycyrrhizate as medicated actives that treat the inflammatory root of sensitivity-related dryness, not just the surface symptom. IHADA is Shiseido's pharmaceutical skincare brand for atopic and allergy-prone skin, formulated to the same low-irritation standards as the IHADA UV range.
How it works: Recurring skin roughness in sensitive and atopic skin is caused by a perpetual dryness-inflammation cycle: dryness allows external irritants to penetrate and trigger inflammation; inflammation further disrupts the barrier; the disrupted barrier allows more dryness. Allantoin breaks this cycle by promoting cellular repair from within — not just moisturising the surface but prompting the skin cells themselves to produce more barrier-supporting proteins, gradually stabilising the skin cycle.
IHADA vs Curel for sensitive skin toners: Both are quasi-drug certified for sensitive skin. Curel uses Ceramide Functioning Ingredient to support barrier repair. IHADA uses Allantoin + Dipotassium Glycyrrhizate to address inflammation + cell renewal + barrier in combination. For skin whose sensitivity manifests primarily as dryness and roughness, both are appropriate. For skin with recurring inflammatory reactions (redness, stinging, breakouts from skincare), IHADA's anti-inflammatory focus is more targeted.
Known in Japan as イハダ 薬用うるおいローション(とてもしっとり)180mL.
