SKIN1004 builds its Madagascar Centella range around centella grown and extracted in Madagascar, and this ampoule is the fermented member of that family. The centella is cultured with lactobacillus before it is blended into the bottle, which is where the Probio half of the name comes from, and the brand lists that fermented filtrate first among the ingredients it highlights.

The liquid is milky rather than clear and sits between a watery essence and a light serum. It sinks in within seconds and finishes silky instead of tacky, so a 95ml bottle is generous enough to use across the whole face twice a day rather than rationing it for flare-ups. The amber glass bottle comes with a dropper, so you can judge the dose rather than guess it.

Niacinamide sits sixth in the list, high enough to matter, and the centella actives follow further down as madecassic acid, asiaticoside and asiatic acid. The lipid side is unusually complete for an ampoule: Ceramide NP, phytosterols, stearic acid and lauric acid all appear, alongside phytosphingosine. Panthenol, betaine, allantoin, sodium hyaluronate and polyglutamic acid cover hydration and comfort.

It suits skin that flushes easily, feels tight after cleansing, or looks flat and tired by the afternoon. The ingredient list carries no fragrance or parfum entry, which makes it an easier choice on days when skin is being fussy about everything else in the routine.
