fvrts Su Boon Jo Serum

What is this product?

fvrts's Su Boon Jo Serum backs its headline claim exactly, which is rare: it advertises 8 types of multi-weight hyaluronic acid and the label carries precisely eight HA forms, from hydrolyzed grades up to a crosspolymer. Niacinamide sits 7th of 38 ingredients and ceramide NP is in there too, so the hydration and barrier story is real as far as it goes. Two things to weigh: a fragrance entry is printed 24th, and this is not the light serum the category implies, because olive oil at 14 and shea butter at 20 give it an oil phase that oily and congestion-prone skin may not want.

What makes it different?

The eight hyaluronic acid forms are the selling point and they survive checking, which cannot be said of most counted-ingredient claims. What the count does not tell you is strength, since none of the eight carries an amount and all of them sit in the last third of the list. The more useful distinction is texture: unlike most hyaluronic acid serums, which are water and humectant only, this one carries olive oil, shea butter, a lecithin and two silicones, so it behaves like a light emulsion and suits dry skin better than oily skin. Ceramide NP is present for barrier work, though cholesterol, the partner lipid that ceramide is usually paired with, is not in the formula at all. Anyone avoiding fragrance should skip it, since a fragrance entry is printed 24th and its composition is not disclosed.

Did the ad claims hold up?

We checked 3 lines this product advertises against the ingredient list and public documents. One of them holds up. The rest are only partly right or have nothing behind them.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
