I used it once, but it didn't suit me, so I'm selling it. Kiehl's Night Mask Retail price: 7,480 yen. Tightens skin! Skincare while you sleep. It tightens the skin from the moment it's applied, providing moisture while leading to smooth skin with firmness and elasticity. Contains naturally derived hibiscus extract *1 and ginger leaf extract *2. It's a smooth, velvety cream mask. As a reward for yourself, deliver plenty of moisture as the final step of your daily skincare routine, and support tightening care. Recommended for use up to 5 times a week. In the evening, after preparing your skin with toner and serum, in the final step of your skincare routine, apply an appropriate amount to the entire face, avoiding the eye area, with a thickness that doesn't allow the skin color to show through, and blend it in with an upward massage. Do not rinse, and go to bed as is. In the morning, rinse with lukewarm water. Recommended for use about 5 times a week.
