A few weeks ago, with an air duster (basically a can of compressed air with a long, thin nozzle).
What facial care products do you use, if any (e.g., moisturiser, BB cream)?

It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air –
There's the rub, the task.
