Do I have to paint my face, or can I wear a mask?

Yes, contact lenses are designed to correct nearsighted and longsighted people. They can be worn as needed such as during college hours.

You should do both. Washing your face first gets rid of the excess dirt and oil, making the mask more effective. Washing your face afterwards gets rid of any residue...

Yes, it is okay, as long as you follow all the directions correctly. Instead of two weeks, throw it out after one week.

It's best to throw it out after use. Since they are made with natural ingredients, bacteria can easily form and make it go bad quickly.

No. If you put the mug in the dishwasher, there is a high probability the paint will come off.

You can use acrylic but you will not get the best results. The acrylic paint will harden the shirt and likely come off in the wash.

Once a week or so should be good. Don't do it too frequently. Oily skin can be treated with masks more frequently, about two to three times a week. Yogurt...

It'll only become darker with each coat. My suggestion would be to use the opposite of red (green) to counter and make it brown or dark.
