Rice paper pack good for whitening effect

Have you heard of Rice Paper Pack?

I'm making a face mask with real edible rice paper haha.

It is said to be good for whitening, reducing swelling, and moisturizing.

1. Cut the rice paper to fit your face.
2. Soak in water, then place it on your face.
3. Remove it after about 5 minutes.

That's so simple haha
