FATION Glucose Hydro Active Serum

Ingredient analysis and how the ad lines read

Read on 2026-09-06

What is this product?

FATION's Glucose Hydro Active Serum is a pure water-holding layer for dehydrated skin, with no oil anywhere in its 62 ingredients, so it needs a cream over it or the water it pulls in just evaporates. The moisture-recovery pitch is well matched to the formula: ectoine, urea, trehalose, glyceryl glucoside and eighteen free amino acids, plus six hyaluronate forms. The brand cites three human-use tests for it (한국피부과학연구원, 22 subjects, spring 2026), all measured against FATION's own hyaluronic acid serum rather than against untreated skin. Two things to know before buying: the glucose the line is named after sits twenty-eighth with no amount given, and menthoxypropanediol at twentieth is a cooling agent that can sting cracked or over-exfoliated skin.

What makes it different?

Most hydrating serums are glycerin and hyaluronic acid with a story attached. This one is built as a natural moisturizing factor replacement instead, running eighteen free amino acids plus urea, ectoine, trehalose and glyceryl glucoside through the middle of the list, and it carries dimethyl sulfone sixth and malachite extract seventh, neither of which is common in the category. It is also completely oil free, which suits oily and congested skin and makes it useless as a standalone moisturizer. The second differentiator is evidence: the brand's launch release footnotes three human-use tests with an institution, a date window and a subject count, which is rare at this tier, and every one of them is scored against FATION's own hyaluronic acid serum rather than against a vehicle or an untreated site. Amounts and pH stay undisclosed, and no brand-controlled product page for this size was retrieved.
