First, read the English article below.

Have all of your facial supplies ready so you're not scrambling around hot water while the steam escapes. You can easily set up your steam facial in the kitchen (nearest the hot water) or the bathroom. You'll need:  A kettle Water 3 to 7 drops of essential oils A thick clean towel A large basin or bowl Fill the kettle with clean water and bring it to a boil. Pour the boiled water into a heat safe bowl or basin. Add your essential oils to the water. Take care when pouring the water or moving the bowl. If you boil the water in the microwave, make sure to place a wooden spoon, utensil, or chopstick into the water. This prevents the water from super-heating which can cause an explosion. Place the basin on a table so you can sit in a chair and lean over the steaming bowl. With your head over the basin, place the towel so that it's draped over the back of your head and completely over the bowl. This will prevent steam from escaping. Be careful not to lean too close to the hot water. Deeply breathe in the steam for 5 to 10 minutes, or as long as the steam lasts. If you need to, you can re-heat the water to get it steaming again. You can reuse the water until it boils dry, adding more essential oils only if you add more water. Since the steam opens your pores, you'll need to rinse your face with cold water when you've finished the steam facial. Cold water acts as an astringent which closes the pores. To further moisturize your skin, apply lotion as soon as you're done with the facial.
