Sorry I was in a hurry when posting the question. I had a request to spray tan a client who has a cold sore and didnt know what to do. So I bluffed it and luckily it was almost gone, so I sprayed as per norm. However, whats the correct proceedure for cold sores? Presumable if they are 'running' its a no no. Does barrier cream irritate them maybe? Any info greatly appreciated. Cheers, Mick.
