Hi just after a little advice, I am starting self employed this week and after reading threads about patch testing RefetoCil I seen that you were to patch test every time, I have just received delivery of my new refetoCil tint and it says on the packaging "patch test is advisable" dose this mean I can patch test the first time and then every 6 months?
Any advice would be great thanks for reading
