Redness, pain and itching after picosure?

I have my lazer surfacing at Hongkong 2,5 months agoby suing picosure.. .I posted a question regarding how to improve the situation that my skin is red and hurt and itching. the redness is sometime very serious and come and go. I called my Dr at hongkong. she looked at my pictures and saying it's result from too dry of my skin. May I ask what kind of hyperating product or serum you suggest in USA? my dr is not familar with USA product. I am very desperated now. thanks
