      "Reduced prominent pores"

      I had prominent pores, as I have oily skin. It has reduced the appearance of pores and reduced oiliness on skin as well.

      Have been using it for 3 weeks consistently in the morning and pores have vanished, skin oiliness has reduced. It takes time to work the magic, but it definitely works. Must try.!!!
