Can I crush the pimples? Remove a mole is dangerous? Psoriasis is contagious? How many questions do in dermatology, because I know that it is trivial, you can have the most beautiful in the physical world, but one side is always sound the best presentation. Chocolate, no chocolate, soap, but as a more neutral or alkaline soap. Light skin, dark, sunscreens. How curious, often fueled by common places that have nothing to science. I found an interesting video, where Dr. Riccarda Serri, a specialist in dermatology at the University of Milan answered in a video interview with Corriere Health, on all these issues, making a clean sweep of all that information is not true.
