I'm nearing three months on spiro and my skin is doing awesome! I had two cysts on my chin but they went away in two days. It was amazing! I don't have whiteheads which is an amazing improvement, as my face used to be flooded with them. Also, my clogged pores have greatly reduced, which some still are home to my forehead area. Oh well, spiro is amazing and has been treating me wonderfully. It's the best thing I've ever tried for my terrible acne.
