Facial sauna is my all the time must have. I have problems with my skin, so need regular and deep cleaning. I deep cleaning facila sauna is good instrument.
so, idea is like that - you put water (or green tee, as I did today with some drops of eucaliptic oil or other oil you or with out it.) On the picture container with water is brown because of green tee (it is boiling there for about 15 minutes). On the bottom of conctuction you put plastic top and switch botton to "2". Water began to boil and steam came out, you put your fac into it and sit like that for about 15 minutes (till the liquid container is empty), if it is too hot for you it is possible to cnahge it to "1". After 15 minutes your pores will be opneed and all of blacheds and impurities will came out. After sauna I clean my face mechanically and than use Himalaya Neem mask. It is famous indian brans, that is popular because of all natural ingridients that they use in process of producing their products.
I got my facial sauna at local supermarket for about 10 euro. It is very cheap and affordable. Hope my tip will help you to get some ideas about facial cleaning.
