I had acne vulgaris, hence I used to use clindamycin phosphate gel, which worked very well, bust as I was out of it, and so was the medical store, he suggested an alternate cream called skinshine which he said works similarly, hence I applied it as usual as I'd apply clindamycin phosphate. But that turned out to be a disaster, I am now suffering from hyper pigmentation with red patches all over the face. Could you please suggest me a cure.
