I have been using homeopathic medicine for my skin issues for the last four weeks and have been getting good results. I apply the berberis aquifolium mother tincture twice daily and also take it internally. Can i wear a sunscreen after applying this mother tincture ?Also I wanted to ask about the homeopathic ointment SBL Berberis Aquifolium Gel. Can i apply this gel and then a sunscreen over it befor i step out in the sun? Or should i only apply the sunscreen before going out in the sun? Plz reply.
