Thanks everyone for your suggestions. Some of them are too expensive for my budget though. I will try the salt water therapy and give Iodine a rest for now. Also I am under a bit of stress now since I have my exams and in a month I am going to Spain for an internship and don't want more pimples.
Will start again with Iodine in September.
Thanks again :)
P.S I am using some vitamin e oil for the scars, you think it might be useful?(just started started and can't tell the difference)
