Hi, I can understand your concern foracne marks and spots. If I were your dermatologist then I would have suggested you to use azelaic acid cream or Kojic acid cream or glycolic acid cream or licorice extract or arbutine creams at night time in guidance of dermatologist. The most important part is to use a sunscreen regularly in open environment and on exposure to sun. Take a proper guidance and follow up with a good dermatologist so that all the problem can be dealt best for future time. Protect yourself form direct sunlight. Take care
