How to use
1. After washing your face, take an amount about the size of a 1-yen coin (0.6 mL) into the palm of your hand. 2. Apply an appropriate amount to your forehead, both cheeks, and chin, and use your entire fingers to massage it into your entire face in a circular motion, lifting the skin as you go. 3. Take a small amount again on your fingertips and apply it to dry areas such as around your eyes, mouth, and chin, and gently massage it in. *If you feel your skin is not moisturized enough, use this product after applying your usual toner. *If you are concerned about sunburn, we recommend using your usual sunscreen after using Skin Tune-Up Serum.
