Claims: what the evidence supports

Brand promiseVerdictEvidence
Reinforced protection in the long-UVA rangeSupportedSupported by published data on the Mexoryl 400 filter and the consistency of the formula, indicating long-UVA protection when the product is used as directed on the label.
Helps limit everyday UVA and UVB exposureSupportedThe SPF50+ category and the photoprotection data support broad-spectrum protection when the product is applied in sufficient quantity and reapplied.
Invisible texture with no white castPartially supportedThis promise depends on the amount applied, skin tone and the context of use; it reflects the cosmetic experience rather than a stable clinical criterion.
Suitable for sensitive skinPartially supportedThe formula may suit some sensitive skin, but tolerance remains individual; stop use if irritation or stinging occurs and seek professional advice if needed.
Water resistancePartially supportedWater resistance should be read against the stated test methods and never removes the need to reapply after swimming, sweating or towelling dry.
Protection around the eye areaPartially supportedThe eye area calls for particular care; freedom from discomfort is not guaranteed for every user.
Prevention of visible sun-related signsPartially supportedDaily photoprotection can help limit visible UV-related damage, but the effect depends on consistency, the amount applied and other exposure.
Protects against all consequences of sun exposureOut of scopeA sunscreen reduces UV exposure but does not cover every risk or pattern of exposure; such wording would be too broad for a cosmetic dossier.
Repairs damaged skinNot demonstratedThe dossier does not support a repair claim; the evidence concerns photoprotection, not the repair of skin that is already damaged.
Guaranteed all-day result after a single applicationNot demonstratedProtection must be renewed as directed on the label; a single application cannot support a stable all-day promise.

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