Ingredients
How to use
ABC-G Repair Serum Before use, apply a small amount (about the size of a 10-yen coin) of this product to the inside of your arm and allow it to dry naturally to check for any adverse reactions. After preparing your skin with lotion, apply it to your entire face. It can also be used on areas where aging is a concern, such as the corners of the eyes, under the eyes, and on the neck. If you have sensitive skin, start with a small amount and gradually allow your skin to get used to retinol*. Once your skin is accustomed to it, use approximately two pumps. It can also be used in the morning, but be sure to use sunscreen. *Retinyl palmitate
