Hi i'm sreevidya 27 year old female. I was using steroidal cream on face for years. But I stopped it before 1 month. And my face is getting dull and small red bumps (like rashes) are appearing in face with itching. I have seen in a you tube channel to use homeopathic medicine berberis aquifolium mother tincture and calendula officinalis mother tincture in face for this problem. I am using it and face is getting better. But once I go to sunlight even with sunscreen small pimples are coming and face is suddenly getting dark. So can I use china officinalis 30 ch internally for reducing melanin? Another combination of medicine for fairness I read was sulphur 6ch, bovista 6ch, sepia 6ch, kalim brom6ch, natrum brom 6ch. Mixed in equal proportion and having it 6 drops 3 times a day internally. Is it safe to have this medicine internally? Does it interact with any medicine? Any side effects? Which one is better to use internally for this issue?
