I was prescribed Tretinoin 0.5% daily or maybe twice a day by my dermatologist to treat stretch marks that were beginning to form in areas showed in the picture. I experienced a bad rash and my skin kept flaking for a many, many months. New skin would form but it would be super thin. Doc covered up it as fungal infection. Anyway, now 2 years later I'm stuck with these patches. I would like to know my options and how much improvement I can expect from the treatments. South asian-- brown skin
