isoi Sebum Care Essence Lotion

What is this product?

isoi Sebum Care Essence Lotion is a 70 ml lotion for oily and combination skin, declared in Korea as a non functional cosmetic, meaning it claims no regulated brightening, wrinkle or UV endpoint. The sebum mechanism is silica at position 10 of 34, an oil absorbing mineral, carried in a light vehicle whose third ingredient is ethanol. The brand discloses the ethanol openly in its FAQ, explains that it is there for a cool light feel in summer, and names which sibling products omit it. A brand coined botanical complex is printed with its five constituents, all of which appear in the list. No concentration is disclosed for any ingredient and no INCI list is published. Of two footnoted headline claims, one resolves to a named clinical institution with an exact two day window but no subject count or result, and the other, satisfaction of 100 percent, has no printed substantiation anywhere. The page claims suitability for all skin including sensitive while the formula carries ethanol, two essential oils and limonene, and the brand's own FAQ routes sensitive skin elsewhere.

What makes it different?

A sebum lotion whose oil control rests on silica rather than an acid, which discloses its added ethanol and the reason for it in its own FAQ, prints the full composition of its named botanical complex, and whose FAQ routes dry and sensitive skin to other products even though the marketing copy above claims all skin types.
