Reaction to IPL on Legs

Hi, I have had a course of IPL on my bikini and underarm area with good results, one of the treatments left me with some red blotchiness for a day or two, but subsequent treatments were fine.

On monday I started a course on my legs and forearms. Monday night my lower legs and feet and knees were covered in swollen red blotches (forearms were fine).

I have been putting an antiseptic/antibiotic cream on it a few times a day and keeping them uncovered until thismorning when I had to put socks/trousers etc on to go to work. At the moment my legs feel sore and itchy, I have taken an anti histamine and paracetamol and have my trousers rolled up at my desk to let the air at my legs (I look rediculous haha!).

My main problem is that I have my brothers wedding next weekend where I will be wearing a dress just over my knees, and litterally have 7 adys left to clear these marks up before I get my spraytan etc done.

Is there any tips advice out there for easing this redness and hopefully clearing up the ugliness within a week!?
