I opened the product, but I found another one that suits me better before using it, so I am listing it without ever using it. It is completely unused. This is a serum containing 0.1% Hydroxypinacolone Retinoate, which refines skin texture and provides firmness. - Brand: VT - Product Name: CICA RETI-A ESSENCE 0.1 - Volume: 30mL - Ingredients: Hydroxypinacolone Retinoate 0.1% Thank you for viewing.
