About a year ago, I was diagnosed with seborrheic dermatitis which also caused an autoimmune disease for a few days. And a week later, I lost a bit of pigmentation in the middle of my unibrow area. My concern is that...Will the skin ever repigment on its own? Does sweating from exercise prevent it from healing? I've found a laser centre that uses Microdermarbrasion for the treatment. Will it work for me?
