How warm does the water have to be to open facial pores?

This is something ive allways thought about,I allways thought it had to be quite hot to open but someone said it doesn%26#039;t have to be hot at all.





And how cold does the water have to be to close them?|||pretty warm. i wouldnt suggest water tho. boil some hot water and put it in a bowl and then hold your head over the bowl and let the steam rise up and caress your face. put a towel over your head to hole the steam in. cold water to closse the pores|||as hot and as cold as you can handle...|||It has to be really warm.... Like pretty hot.|||i actually use hot water. Wet a towel with hot water and then stick it on your face|||its easier to get acne in warm
