I double cleanse only at night because sunscreen/makeup can be difficult to remove. It is the agitation of the molecules in the cleanser on your face which removes the sunscreen/makeup. So spending a minute gently rubbing the cleanser will clean your face which could make a single cleanse effective. It also depends what type of cleansers you use.
So you basically do it on demand if I got it right. If the first cleanse get's it off, no reason to worry further
I don’t ☺️
