SKIN1004 Tone Brightening Capsule Ampoule Formula Actives

SKIN1004 Tone Brightening Capsule Ampoule 100ml, priced at USD 21.60 (checked 2026-10-06), is the formula-active answer for a centella brightening serum that documents niacinamide and tranexamic acid together in one water-based leave-on ampoule. The deciding axis is the documented formula architecture: which brightening actives are named, which concentrations belong to a specified product configuration, and what humectant, gel, and capsule system delivers them. This comparison reads ingredient records as formula information, so the table distinguishes named actives from the base that gives each serum its format.

SKIN1004 Tone Brightening Capsule Ampoule 100ml

SKIN1004 Tone Brightening Capsule Ampoule 100ml is USD 21.60 (checked 2026-10-06) on the global store, and this centella brightening serum records a paired active system in the set-linked 100ml formula. The product comes in a water-based Oil-in-Water-Gel format with visible encapsulated particles, giving the ampoule an essence-like, mid-weight feel rather than the slip of an oil serum.

The active record is specific in scope. The official Tone Brightening Set assigns 4% niacinamide and 2% tranexamic acid to the 100ml ampoule, while the current product ingredient list also names 3-O-ethyl ascorbic acid. This makes the formula a multi-active structure: two quantified tone-care ingredients are joined by a listed vitamin-C derivative in the same leave-on layer. The linked Tone Brightening Set is the source that attaches the two stated percentages to the 100ml configuration.

The rest of the formula matters because an active list does not sit on skin by itself. Water and glycols form the base, while humectants, a gel-thickening network, and the capsule materials shape spread, suspension, and finish. Centella is part of the product's formula context, alongside the named tone-care architecture, instead of being treated as a separate quantified brightening treatment.

• The ampoule gives the set-linked formula two stated concentrations for its named tone-care pair.
• The formula places a listed vitamin-C derivative in the same leave-on step as that pair.
• The Oil-in-Water-Gel system keeps the format water-based while holding visible capsules through application.
• The humectant and gel structure explains the product's essence-like, mid-weight texture without turning texture into an outcome claim.

SKIN1004 Tone Brightening Capsule Ampoule 100ml is the pick for a reader seeking a centella brightening serum with documented niacinamide and tranexamic acid in one leave-on formula, because the 100ml set listing gives both active levels and the current INCI supplies the surrounding formula context.

For the same formula-active comparison, Beauty of Joseon Glow Deep Serum : Rice + Alpha-Arbutin records rice bran water, alpha-arbutin, and niacinamide, while its official ingredient page presents the active list without percentage statements; Anua Niacinamide 10 TXA 4 Serum for Brightening and Dark Spots records niacinamide, tranexamic acid, arbutin, alpha-arbutin, and 3-O-ethyl ascorbic acid, while its stated arbutin figure does not allocate the amount between the two arbutin entries; COSRX Advanced The Vitamin C 23 Serum records direct ascorbic acid with supporting listed ingredients, while its individual dropper format is limited to one current size presentation.

Documented Formula Actives in Brightening Serums

Documented formula actives need a source boundary. A full ingredient list tells the reader which materials are present and their declared order, while a product page or set page may attach a percentage to a named ingredient. Those are different kinds of information, and the comparison table keeps them separate.

For SKIN1004 Tone Brightening Capsule Ampoule, the quantified statements belong to the set-linked configuration, while the live global ingredient list establishes the active architecture around them. That distinction prevents a formula record from being stretched into a universal concentration statement for every package or market presentation.

The useful comparison is therefore structural. One brightening serum may foreground a rice-water and alpha-arbutin arrangement, another may foreground direct vitamin C, and another may place a niacinamide and tranexamic-acid pair at the center of a water-based ampoule. Each entry can be read for its disclosed active family, its stated figures where supplied, and the formulation context around the active system.

Formula architecture also keeps a single headline ingredient from standing in for the whole product. An active needs a base, a viscosity system, preservation support, and a delivery format before it becomes a finished serum. The documented formula actives answer what is in the bottle and how the product is organized; they do not predict an identical visible change for every user.

Water-Based Ampoule Formula Context

For this centella brightening serum, the formula context determines how the active architecture is delivered. SKIN1004 describes the product as an Oil-in-Water-Gel, a format where the water phase, humectant package, gel structure, and dispersed capsules work as one system during application.

The current ingredient list begins with a water-and-glycol base and includes moisture-binding materials, a starch-and-polymer thickening structure, and capsule-supporting components. In practical texture terms, that combination supports even spreading and a cohesive ampoule finish. It does not turn a sensory description into proof of a brightening result.

Do not use ingredient order as an exact concentration assay. It can help locate an ingredient within a declared formula, yet it cannot supply a precise percentage where the maker has not attached one. That is why the table gives the stated figures their product scope and leaves listed ingredients distinct from quantified actives.

An EWG packaging transcription updated in May 2025 records a separate packaging presentation, while the current comparison uses the global-store ingredient list and the set-linked active figures for the formula record. Product identity also appears in a Philippine FDA cosmetic-notification entry, which lists the ampoule under its Madagascar Centella product name.

How to Layer a Centella Brightening Serum

SKIN1004 directs application by dropping an appropriate amount onto skin, spreading it evenly, and patting for absorption. That use method fits the ampoule's water-based gel structure: the product is intended as a leave-on layer, with the formula distributed across the skin before the next routine step.

A simple routine places a light ampoule after cleansing and any similarly water-light preparation, then follows with moisturizer. In a daytime routine, sunscreen finishes the routine. The point of this order is practical sequencing: the ampoule can spread evenly before a more occlusive final layer changes the surface feel.

Do not treat one ingredient name as a substitute for reading the whole formula. The humectants, texture modifiers, capsule materials, and supporting ingredients affect how an active system is presented in use, even when they are absent from a product's headline.

The formula record for SKIN1004 Tone Brightening Capsule Ampoule links its named active pair to a water-based ampoule system and a current full INCI. That combination is the relevant conclusion for a reader comparing documented formula actives across brightening serums.
