hi, It's up to you about using salt water but - I made my own solution using filterd water and natrual sea salt/rocks crystals.
I would wash my face then I would put on a light mouistriser let it absorb in to my skin and then splash the self made salt water on my face/neck afterwards....
but after a few days it made me break out, and the spots were really big and painfull to
some people say salt can clear there acne but it didnt work for me
although when I go swimming aboroad salt water can clear you're skin a treat.
I bought one of then red n blue face lamps last week for £200 of a uk website, I think it maybe working but it's early days yet and you have to put you're face closer to it then they say for it to be effective....In another week or so I will put a post on to say how effective it really is.
