Ingredients
How to use
Use once or twice a week. 1. Use at night after toning your skin with lotion. Holding the handle in your right hand, remove the mask from the bag and slowly unfold it. (Some of the liquid may drip out, so be careful not to stain your clothes.) 2. Place the mask on your face, with the handle on the right side, aligned with your eyes (eye shape), and make sure it adheres to your forehead, cheeks, around your mouth, and nose. *Make sure the folded inner side is on your skin. 3. Then, while holding the sides of your nose and around your mouth, hold the cheeks and pull each side up toward your temples, overlapping the mask firmly to ensure it adheres properly. *If you apply the wrong side to your skin, the overlapping parts of the mask will not adhere properly. If this happens, reapply. 4. Leave the mask on for 10 minutes, then remove it and massage any remaining liquid into your skin with your palms.

It's comfortable to use and doesn't leave a sticky feeling after peeling, and it leaves your skin feeling toned and white. It feels so good that I keep it on hand and use it frequently.
This mask is a lifesaver when you've been exposed to too much UV rays. During a trip to Hawaii, I was active, visiting the beach, pool, and hiking. Even though I'd taken precautions against UV rays, I still ended up getting a lot of exposure. I checked my skin's condition and used this one night. The sheet is thick and adheres perfectly. It has a front and back, so it's a good idea to read the instructions on the back of the package carefully. The unique procedure involves applying one side first, then the other. It holds your face in place, lifting it up, so after removing it 10 minutes later, your face line feels incredibly refreshed. And best of all, it removes dullness better than any other whitening pack I've ever used. My family even commented on how white it looked, which I was impressed with. It's not recommended for daily use, only once or twice a week. It's expensive, but I plan to repurchase it as a special mask for when I've been exposed to UV rays or on the morning of an important appointment. I also love the scent, which is similar to the gentle serum.
I use it once a week as a special treatment. It makes my skin whiter and softer (lol). It makes my makeup look so much better the next day. However, it's a little pricey.
I bought this as a wedding gift for a friend. I've used Whitelogist before, and I can visibly see that my skin is brighter the next morning!
