How to use
Before use, apply a thin layer of this product (about the size of a 10 yen coin) to the inside of your arm, let it dry naturally, and check for any abnormalities. After toning your skin with lotion, etc., apply it to your entire face. You can also use it on the corners of your eyes, under your eyes, and around your neck, where signs of aging are a concern. If you have sensitive skin, start with a small amount and gradually allow your skin to get used to the retinol*. Once your skin has gotten used to it, use two pumps as a guide. You can also use it in the morning, but be sure to use sunscreen. *Retinol palmitate
