You want to make sure that your hands are clean and dry before you massage your eyelids, otherwise you could risk irritating your eyes or causing pimples (styes) to form. You can also use a clean washcloth soaked in very warm water. Just be sure that the water isn’t so hot that it burns your skin. This will help unclog pores and deep clean your eyelids and lash line.

TL;DR in Vietnamese:
Rửa và lau khô tay. Chườm ấm mí mắt.
