IHADA Medicated Moist Emulsion 135ml is the sealing emulsion step for the IHADA medicated sensitive-skin routine — applying a second dose of Allantoin and Dipotassium Glycyrrhizate in a lightweight milky emulsion that locks in the toner's moisture and extends the medicated actives' contact time with the sensitised skin surface. Used after the IHADA Medicated Moist Lotion as the second step in the quasi-drug duo.
How it works: The emulsion applies Ultra-Pure Petrolatum as a final barrier layer over the toner — petrolatum is clinically validated as one of the most effective barrier-occlusive ingredients for atopic and sensitive skin (it is a key component of numerous dermatologist-recommended barrier creams). In IHADA's ultra-pure refined form, it provides the same occlusive benefit without the impurities in standard petrolatum that can cause sensitivity in already-reactive skin.
IHADA toner + emulsion as a pair — is both necessary? For skin with atopic or recurring sensitivity, yes — the medicated actives deliver more cumulative benefit at two sequential steps than at one step alone, and the emulsion's petrolatum seal is necessary to maintain the barrier through a full day or night. For milder sensitivity where the toner alone provides sufficient stability, the emulsion can be used every other day as a maintenance step.
Known in Japan as イハダ 薬用うるおいエマルジョン 135mL.
