I had the same problem lately. I went to dermatologist and I was prescribed 3 kinds of drugs (yemiwat, yemikeba & samuna) I used it like for 3 months but no change. I met my sister after more than 18 months and there was amazing change on her face. Here is what she has been using:- Banana peel, turmeric, honey, aloe vera (natural), olive oil, chick pea powder. I started using it like for 2 weeks and there is magical change on my face.
