I got my eyebrows done and now I have red marks by my eyebrow. What can I do to prevent scarring? I am in Accutane for a month.

Not a good idea!!However, I doubt that you actually scarred your skin, more probably just inflamed and irritated it.You can get 1% Hydrocortisone over the counter and it should,within a day or two solve the problem.Meanwhile, don't wax again until you are done with the treatment.

First, you should NOT wax while on Accutane. You can use OTC hydrocortisone on the red areas. But in the future, don't wax while taking Accutane - it's not advisable! "This
