Hydrating and brightening sheet masks [SEP] I've been using sheet masks for years and these masks have a lovely texture. There are generous amounts of serum and the mask stays moist for over 20 minutes.<br /><br />Overall, these are a great complement to the other skincare products and sheet masks that I use regularly.  I have sensitive combination skin and this did not cause any redness, sensitivity or irritation.<br /><br />If this was helpful to you, please indicate it below.
