Actually both....in the morning to remove all the stuff tha builds up at night and at night to remove the stuff that builds up during the day! Too much washing will dry out your skin, use a good soap and moisturizer!
Is it better to wash my face morning or night or both?
Both. Because at night it's good to get all the sweat and stuff off, and then in the morning to clean out your pores, it also helps wake you up. /)
Yes it is very beneficial for face.
Both
I think both day and night
I'm going to answer your question, yah! If I had to chose only one I'd say night time, because your face gets dirtier throughout the day than while you're sleeping. It also makes a difference, because if you wash your face before going to bed, then your pillow will be cleaner. Maybe I'm just biased though, because that's what I do. :)
I wash my face at night but both I would say.
