Follow up to my previous question: Rough red spot on legs 3 weeks after IPL Hair Removal. (photo)

I got my 3rd ipl hair removal almost 3 weeks ago;and developed a red bumpy itchy rash all over my legs that were treated. Now the itchiness has calmed down, but I am left with very rough skin, and full of ugly red spots. Ive been religiously applying aloe vera gel to my legs, but it doesnt seem to help much. im afraid that the red dots will stay there permanently. is there anything i can do to improve this? Is this a normal reaction after ipl hair removal?
