I used a homeopathic medicine 'thuja' after that i have so many pimple one after one, because of these pimples i have spots on my skin like atrophic?

Consult homeopath: Thuja is a good homeopathic medicine for a variety of skin problems including acne. It can help our bodies detox and skin eruptions can be a way we detoxify. Over time these spots may heal, but this may also be a sign Thuja has acted as well as it can and now it is time for a different remedy to help these spots to heal. I advise you consult with a good homeopath, and, fortunately, India has many!
