Clé de Peau Beauté Sérum Concentré Éclaircissant n Whitening Serum Purchased in a Tokyo store in September 2025. Used two pumps, morning and night, for several days. Retail price: ¥18,700 (40ml) Remaining amount: Approximately 70-80% (see image 4) * Even if new, the bottle is not filled to the brim. Considering that one bottle typically lasts for 1.5 months, I estimate 70-80%. This is just my subjective assessment, so please use it as a reference. As this is a used item, please refrain from purchasing if you have any concerns. No box. Will be wrapped in bubble wrap and packaged for shipping.
