Key Ingredients
FAQ
What makes this different from regular moisturizers?
It's medicated (quasi-drug status in Japan) with allantoin and dipotassium glycyrrhizate as anti-inflammatory actives. The formula is built around high-purity petrolatum technology that forms a protective film over the skin barrier without feeling greasy. It's designed for people with eczema-prone, reactive, or severely sensitive skin who can't tolerate most skincare products.
When do I use this in my routine?
After your toner and serum, before any heavier creams or occlusives. The emulsion format (乳液) is thinner than a cream but thicker than a serum. In the Japanese skincare system, emulsion comes after your watery layers (toner, essence) and provides a light moisturizing and protective layer. If you have very dry skin, you can layer a cream on top. If you have oily or combination skin, this might be your final step.
Can I use this if I have acne?
Yes, if your acne is related to irritation or a damaged barrier. IHADA is formulated for sensitive, reactive skin and is fragrance-free and hypoallergenic. The anti-inflammatory actives can help calm redness and irritation. However, if your acne is primarily hormonal or bacterial, you'll need targeted acne treatments in addition to this. IHADA won't treat acne, but it won't make it worse either.
