Thoa cồn isopropyl.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
Rubbing alcohol (a.k.a. isopropyl alcohol) is probably the most effective product for removing permanent marker from skin.  Dip a cotton ball in the rubbing alcohol and then hold it on the skin for a few seconds. Once you’ve done this, wipe and repeat until the mark is gone – do not rub, as this can irritate the skin. Rubbing alcohol is available at the pharmacy/drugstore -- look for a 90% solution or higher.
