EQQUALBERRY Original serum: fruit-water percentage and clinical imagery are separate claims

Read the 40% acerola-water statement, declared niacinamide amount and illustrative result images without turning them into a pure-vitamin-C or verified-patient claim.

An editorial reading of public records. No clinician sign-off, patient outcome study, firsthand product test or examination of a supplied medicine is claimed.

EQQUALBERRY’s Vitamin Illuminating Serum Original places a forty-percent acerola claim beside brightening language and result imagery. The ingredient attached to the number is acerola fruit water. Keeping that full description matters: shortening it to forty percent vitamin C would create a different and unsupported statement about the finished serum.

The official Original 30 mL listing and refund policy were checked on October 14, 2026. The standalone serum was marked sold out, while nearby bundles had their own prices. This review examines the declaration, study reference and purchase conditions. It does not include an authenticated bottle, independent image verification or a test of the formula on skin.

Follow the record

The percentage must retain the name of its material

The ingredient list declares acerola fruit water at 400,000 ppm. That corresponds to forty percent on the same measurement basis; it is not a specification of forty percent isolated vitamin C. A fruit’s association with a nutrient does not establish the nutrient’s concentration in a prepared ingredient or the whole cosmetic. Source 1

The formula separately names 3-O-ethyl ascorbic acid at 10 ppm. Those entries should remain distinct. Our active-name comparison applies the same principle to other ingredients: record the material actually named before comparing numbers. Otherwise, a mathematically precise conversion can still describe the wrong substance.

Some amounts are supplied and others remain unknown

Niacinamide appears at 40,000 ppm, equivalent to four percent. Arbutin, tranexamic acid and numerous other ingredients are also listed, but their presence does not establish an exact amount unless the declaration supplies one. The highlighted ingredient panel should not be treated as a complete quantitative formula. Source 1

The product-label questions help organize a request for missing information without inventing it from promotional emphasis. A formula can contain several familiar brightening ingredients while leaving the contribution of each one unresolved. We did not measure ingredient levels or appraise a study that isolates the effect of every constituent in the marketed serum.

A study identifier does not authenticate every image

The page cites Intertek Testing Services Korea, a study identifier and dates in 2024 in connection with its tone-improvement language. It also labels the before-and-after images as illustrative. That distinction prevents the pictures from being treated as independently verified photographs of the cited participants or as this publication’s evidence of their outcomes. Source 1

We did not inspect a complete report resolving participant selection, controls, imaging conditions and outcome calculations. The testimonial discussion explains why an accessible visual summary can still leave causal questions unanswered. The existence of a study reference is useful, but it does not license inventing the details needed to evaluate its result.

The seller’s routine advice is not an individual assessment

The FAQ presents morning and evening use and broad compatibility with other ingredients. Those statements describe the manufacturer’s general positioning. They do not establish how the full serum will interact with an individual’s prescriptions, known sensitivities or recent procedures. We did not test any combination or observe a wear result. Source 1

AAD guidance on introducing new skincare supports trying products carefully and noticing irritation. It cannot confirm that a broad compatibility statement applies to every reader. A current full label is also more relevant to a particular sensitivity than the vitamin-centered product name alone. Keep personal treatment questions with a qualified professional who knows the actual situation. Source 3

The sold-out record should not borrow a bundle price

The checked standalone Original page identified 30 mL and displayed sold out. Separate offers nearby combined the serum with a cream, toner or larger routine. Those bundles represent different quantities and products; their prices cannot be reported as the verified price or availability of the single bottle. Source 1

The price-wording guide encourages a comparison of what is actually being purchased. A larger basket can increase spending and add several unfamiliar formulas at once. We did not establish a restock date, verify a selected bundle’s stock or complete an order, so this record does not promise when a reader could receive the serum.

Return categories depend on the reason and product condition

The policy allows change-of-mind requests within thirty days of receipt for unused items with original packaging and proof of purchase. It specifies FedEx for return shipments and states that return-shipping costs are deducted from the refund. This is a conditional unused-return process rather than an unrestricted satisfaction trial for an opened bottle. Source 2

Wrong, damaged or defective goods follow a separate evidence process, while irritation and safety concerns are escalated to the company for review. The latter may require the product name, lot information and details of the issue. We did not submit a claim, so the policy cannot be used here to promise approval, a response time or the outcome of a specific case.

Keep the exact Original record available for a later purchase

The product family contains several related names and bundles. A future listing may differ in availability, package or formula, so retain the current Original name and declaration when comparing sources. Another member of the range does not supply missing concentration, price or clinical information for this serum merely because its branding matches.

The new entry in our claim directory isolates the fruit-water percentage question. The broader review leaves three boundaries intact: a fruit ingredient is not pure vitamin C, illustrative images are not verified patient records, and a bundle is not a standalone bottle. Those distinctions make the evidence easier to use without turning this publication into a product-testing laboratory.
