Hi there, I'm here to ask about the problematic pimples which frequently stay on my face and has caused many brown spots over. These pimples sometimes get vanished but often they be back, mostly when my face's skin is exposed to my pillow while at night. Only if for one day I keep my face's skin touched to my pillow it causes me pimples on those portion whichever has been exposed to. Problem lie since I was 12. I'm currently having some homeopathic medicinal treatment with Echinacea Angustifolia but I wonder that yet there are no good results. Some of 'em are red and some are yellowish white filled with puss. Hope your consultation will be useful. Thank-you
