System Verdict
This is a decent cosmetic eye cream with good concealing optics, but the “filling” claim is mostly marketing. The efficacy score is driven by a solid base of glycerin, butylene glycol, sodium hyaluronate, dimethicone, and film-formers that can temporarily smooth and blur the under-eye area; caffeine may modestly help puffiness. The peptide and botanical complex are present, but the formula does not show a strongly treatment-level active system or any clear evidence of a high, transformative concentration, so the result is better as a short-term appearance enhancer than a true corrective eye treatment.
