Hello, You have suffered from the side effects of the prescription medicine for acne given by your treating doctor. Now you are having white spots. The white spots should go away with time. However, you can get clinically examined by a dermatologist and get ultraviolet light treatment in combination with topical medications for quicker response & better treatment. In the meantime, you can take food rich in calcium, vitamin D and vitamin E or supplements to make up any vitamin deficiency that can cause white spots. You can apply a thin layer of low dose corticosteroid cream at bed time (not when outdoors) so that the skin gets blended. But it will take time. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
