Pesky pimples. Who can really cure them.

Hello doctor I am 26 year of married female. I have got rashes like tiny  pesky pimples all over my hands and now that's growing on my forehead and face.,which cause dark spot if not pesky and if pesky by hand again that causes dark spots. I have checked this earlier but they only prescribe me some sunscreen lotion and a face wash but that really doesn't work for me. My face completely has dark spots now and am really worried that's don't look good. I use lacto calamine as my daily moisture only. Please suggest some dark spot removing creme and remedy for these pesky rashes like very small tiny pimples but when u closely see that and give them a stress a kind of white small thing comes out. Please suggest medication and doctor in pune who can really cure them.
