PRODUCTS

Where is Oguma from?

We originated from Japan, discovered by Dr. Oguma from Shinbashi, Tokyo. Deciding to apply his discovery in the field of skincare, we relocated to Taiwan where it serves as our headquarters. Our products are all manufactured and produced in Taiwan.

I have sensitive skin, is it safe to use Oguma products?

Sensitive skin is often a result of poor hydration and nutrition in the skin. Our products are designed specifically to counter this problem, treating your skin with rich nutrients and moisture. However, do note that even though our products contain all natural ingredients, it does not guarantee to be 100% safe. If you find your skin having an allergic reaction or feel any discomfort, cease using the product immediately.

Are your products all natural?

Yes, all our products contain only natural ingredients. Some contain ingredients from the sea, like Brittany salt and our famous Ion Complex Elite for instance. While others contain extracts from plants and in some cases, hyaluronic acid.

What is the difference between Mitsuion and AllDay Spa?

Mitsuion and AllDay Spa are virtually identical in terms of contents and functions served. The difference is the AllDay Spa comes with a small bottle of Hyaluronic Acid, a natural ingredient found in our own skin cells.

It is used by our skin to maintain moisture levels and when applied in the AllDay Spa, it helps your skin retain as much moisture as possible so your skin feels and appears hydrated, plump and healthy.
