Drying times may vary depending on individual skin conditions. Even if the product does not become transparent quickly, rest assured that moisture and nutrients are being delivered to your skin during use. Since it’s an overnight product, is it okay to wear it while sleeping? Can be used as a sleeping mask. We recommend wearing it for about 3-4 hours. Please be sure to follow the usage instructions carefully. How many times a week is it appropriate to use? Moisturizing is an essential part of any skincare routine. For healthy and radiant skin, we recommend using the mask 3-4 times a week. However, it is also perfectly fine to use it daily, depending on your skin's need.
