I am lady, 46 yrs old, diagnosed with drug allergy. Now rashes all over my body are dry but marks still there. My derma prescribed be Depiwhite body milk, after using Ellocom, lipobase cream and cetaphil. He said Depiwhite only for now and Vitamin A 50,000 iu ...and Vitamin C 1g. Marks he said will be gone, but will take time. Any idea how long will the marks be gone and Depiwhite will help me get rid of the marks?
