[Kiehl's Cream UFC] After cleansing in the morning and evening and toning with lotion and serum, take a pearl-sized amount (about 8mm) and place five dots on your forehead, both cheeks, nose, and chin. Gently spread the cream over your entire face to reduce friction on the skin while delivering moisture* to the entire face. After applying to the entire face, press with your hands to deliver the cream deep into the skin*. For areas of concern that are dry, apply a second layer for thorough hydration. * Retains the stratum corneum. [Kiehl's DS RTN Renewing Serum] For daily care, after toning with lotion, apply 2-3 pumps to the entire face, then moisturize with a cream or other product. It can also be used on the delicate skin under the eyes, around the eyes, and on the neck. However, avoid the particularly delicate skin on the upper eyelids and lips, and be careful not to get it in your eyes. It can also be used on the neck and décolleté; use approximately 1 pump. For customers experiencing retinol* for the first time: Start with a small amount every other day to allow your skin to comfortably adjust to retinol*. Then, use once a day while observing your skin's condition. If you experience irritation, we recommend using it after a cream. Please read the instructions and precautions carefully before use. * Retinol (skin conditioning ingredient) ※We recommend refraining from using this product if you are pregnant or breastfeeding, or if your skin is particularly sensitive, such as immediately after waxing or laser treatment.
