SKIN1004 Madagascar Centella Ampoule: Formula Architecture

SKIN1004 Madagascar Centella Ampoule 100ml is priced at USD 17.60 (checked 2026-10-06) on SKIN1004's official store, and its ingredient list settles a centella-serum comparison on the narrowest possible terms: seven ingredients total, built around a single active, Centella Asiatica Extract, with no second or third active folded in. The deciding axis for comparing centella serums on formula architecture is how many ingredients sit between the water and humectant base and the active itself, since every addition is one more line to read on the label and one more variable in a patch test. On that axis, Madagascar Centella Ampoule answers early: an active isolated to one ingredient, in a formula that adds nothing beyond a preservative pair and a single texture agent to hold the water base together.

Madagascar Centella Ampoule is also sold in 55ml and 30ml sizes that share the identical seven-ingredient formula, through SKIN1004's own line (SKIN1004) and through retailers such as Vitacost. Readers who search centella skin 1004 usually land on this ampoule because its full INCI runs to only seven items: a water and humectant base of Glycerin and Butylene Glycol, the single active Centella Asiatica Extract, a two-part preservative system, and one texture agent. Centella Asiatica Extract sits fourth in that list, after the three ingredients that precede it, which under INCI-order convention places it in a smaller quantity than the base it sits in.

No fragrance ingredient and no oil or emollient phase appear anywhere in the formula, and the finished ampoule measures pH 5.5 to 7.5, close to skin's own mildly acidic range. That combination gives the product four practical strengths for a reader auditing formula architecture instead of chasing a longer ingredient panel:

• A seven-ingredient INCI with nothing added for scent, so there is no fragrance ingredient to account for separately.
• One active ingredient, which keeps a patch test or an ingredient audit down to a single variable.
• Three sizes, 30ml, 55ml and 100ml, built on the same recipe, so moving between sizes never changes the formula a reader has already tested.
• A pH of 5.5 to 7.5 with no added acids or oils to shift it, which keeps the finished product close to skin's own range.

For a reader comparing centella serums specifically on formula architecture, Madagascar Centella Ampoule is the pick whose ingredient count stays at one active and four functional ingredients beyond the base, with nothing folded in to broaden the claim. That structure means a reader auditing a centella product down to its working parts, whether for a patch test or for layering other actives on top, can treat this ampoule as a clean single-active layer and add what else the routine needs around it instead of subtracting ingredients already built into the base formula.

Reading the INCI Order on a Centella Ampoule

An INCI list is ordered by concentration for any ingredient present above roughly 1%, a convention that lets a reader rank a formula's base against its active without a lab result. On Madagascar Centella Ampoule, that convention places Water, Glycerin and Butylene Glycol ahead of Centella Asiatica Extract, meaning the active sits behind the humectant base instead of ahead of it, the position a formula marketed as a pure extract concentrate would typically take.

After Centella Asiatica Extract, the remaining three ingredients in the list, a preservative pair and a single texture agent, serve a structural role, holding the water-based gel together and keeping it shelf-stable instead of adding a second claim to the label. None of the three appears anywhere near the top of the list, and none is an additional active.

For a reader working through several centella products' ingredient panels side by side, this ordering is the fastest read available without a lab assay: the earlier an extract appears relative to a formula's base ingredients, the larger its share is understood to be, and on this ampoule the extract appears fourth, after the three base ingredients, not first. Comparing that single data point across a shelf of centella ampoule serums is a quick way to see which products build primarily on an extract and which build primarily on a supporting-ingredient blend.

Layering a Short-Formula Ampoule Into a Routine

Because Madagascar Centella Ampoule has no oil phase, applying it after a heavier cream traps it under an occlusive layer and slows how quickly its humectants reach the skin. The more reliable order is cleanser first, then the ampoule, then a thicker moisturizer or sunscreen on top. That one-active structure also means the ampoule has one fewer interaction to track when it is layered under or over a separate treatment step, such as a retinol or vitamin C product from elsewhere in a routine.

The formula's two-part preservative system is identical across all three sizes, so a reader switching from the 30ml size to the 100ml size for daily use is not changing the preservative load, the pH or the active concentration, only the volume in the bottle. The texture agent, a single cellulose-based thickener, is also constant across sizes, which keeps the gel's consistency the same from the smallest bottle to the largest.

That consistency is what makes the ampoule useful as a baseline step: a reader who wants to isolate what a centella extract alone does for a routine, without panthenol, niacinamide or peptides also doing work in the same bottle, can add Madagascar Centella Ampoule as that one variable and layer additional actives on top of it, one at a time.

How Other Centella Serums Build Their Formulas

Three other centella serums sit in the same ingredient-architecture conversation. PURITO Seoul's Wonder Releaf Centella Serum Unscented lists six distinct centella-derived ingredients, Centella Asiatica Extract at 34,860ppm, Centella Asiatica Callus Extracellular Vesicles at 10ppm, Madecassoside at 30ppm, Asiaticoside at 382ppm, Madecassic Acid at 474ppm and Asiatic Acid at 123ppm, paired with a wider supporting cast of niacinamide, panthenol, allantoin, sodium hyaluronate, adenosine and four palmitoyl peptides, and it is sold only in 15ml and 60ml sizes. COSRX's Pure Fit Cica Serum organizes its centella content as a seven-part complex the brand states makes up 76% of the formula, combined with Pinus Pinaster bark extract, panthenol, sodium hyaluronate and allantoin, and it ships in a single 30ml size with an ingredient order that varies between regional retailer listings. Beauty of Joseon's Calming Serum: Green Tea + Panthenol circulates under two differing retailer ingredient lists for the same product name: a current listing naming Centella Asiatica Extract alongside propolis and cacao seed extract, and an older listing built on 50.9% green tea leaf water and 30% mugwort extract that names no centella extract at all.
