I have some pretty bad acne on my forehead...is there any way I can lose it by my date in 3 days' time?

Stress can cause acne, but (and it doesn't always fade away with age) some people just have it. Either way, I would recommend using Nutregena cleansing pads. It is a small, round plastic container, and you can get it at Target, Meijer, Walmart...for about $6-7. It can make a difference for me in a day or two if I get a break-out. I would also suggest getting an on-the-spot acne cream to apply to all your problem areas.
