For daily skincare, after toning with lotion, apply 2-3 pumps to the entire face, then follow with cream or lotion. Nighttime use is recommended. Avoid use on the upper eyelids and lips, where the skin is particularly thin. Be careful not to get it in your eyes. Use one pump on the neck and décolleté. Always use sunscreen when using in the morning. *Do not use while pregnant or nursing. *Do not use if your skin is particularly sensitive or immediately after laser or wax treatment. [For customers experiencing retinol*1 for the first time] - Start with a small amount every two days to allow your skin to become accustomed to retinol*1. Then, use once a day while monitoring your skin's condition. If you are concerned about irritation, we recommend using it after cream. *1 Retinol (skin conditioning ingredient)
