This product is not sold in Japan. Domestic suggested retail price (imported): ¥8800 Available for immediate purchase. Purchased in March 2025 from an online pharmacy overseas. I bought two and used one. I usually use stronger retinol skincare products, so I found this one to be too mild, and am selling the second one. Although it is unused, there is some slight damage to the box that occurred during transit. La Roche-Posay's "Retinol B3 Serum" is a serum for the face and neck with a light texture that is easily absorbed into the skin. The combination of retinol and vitamin B3 helps to reduce the appearance of fine lines caused by dryness. It improves skin texture and tone, increases hydration, and leads to a plump and supple skin impression. This product is for retinol beginners who want to minimize retinol damage.
