Claims: what the evidence supports

Brand promiseVerdictEvidence
Provides 10% niacinamide in a short water-based formula with zinc PCASupported, within a narrow frameThe official The Ordinary page and INCI Decoder cross-check the Niacinamide 10% + Zinc 1% positioning and a water-based formula centred on niacinamide and zinc PCA; this supports the formula reading, not clinical superiority of the SKU.
Can support a cosmetic routine targeting the look of shine, pores and uneven visible textureSupported, within a narrow frameOpened niacinamide publications describe possible cosmetic effects on barrier, visible redness, yellowing/hyperpigmentation and texture; extrapolation to this product remains cautious and depends on individual tolerance.
Fits best as a supporting serum rather than a standalone blemish solutionSupported, within a narrow frameThe opened sources do not document a finished-product The Ordinary trial against acne. The safest reading is a cosmetic routine support, with discontinuation if irritation occurs.
Demonstrably reduces the appearance of inflammatory acneNot demonstratedNone of the retained open sources demonstrates that this SKU corrects inflammatory acne. CosmeticFountain therefore classifies this promise as not demonstrated.
Suitable for every sensitive skin from the first applicationPartially supportedThe formula is simple and fragrance-free, but 10% niacinamide may sting for some people; tolerance should be checked gradually.

What the evidence does not show. The evidence does not allow the promise to be extended beyond the measured criteria.

Formulation

An INCI reading and the coherence of the formula with the headline promise. Ingredients can support the plausibility of a formula; they are no substitute for evidence on the finished product.

INCI — key actives and filters

  • Niacinamide
  • Zinc PCA

Safety and precautions

Le dossier soutient surtout une logique ingrédient-formule. Les preuves ouvertes concernent la niacinamide topique et le contexte cosméceutique; elles ne démontrent pas que ce SKU améliore l’aspect d’une poussée inflammatoire ou remplace un avis qualifié.

Pregnancy or breastfeeding: seek professional or pharmacy advice before use, particularly with a device or a potentially irritating active.

Take care if: damaged skin, persistent irritation, photosensitivity, ongoing dermatological care.

Usage advice

Follow the product label. Pair when relevant with simple barrier care and suitable sun protection.
