I have been using Cor - The Silver Soap for a week now and here are my thoughts.
It has a really nice fruity scent (contains pomegranate). The instructions say not to leave the soap uncovered due to the fact that it can melt if it comes in contact with moisture. I covered it up in clingfilm and put it in a little dish in the bathroom. I have also found that the soap will last a lot longer than the week to ten days suggested - I think it will last at least 3-4 weeks making it great value.
Day 1: I followed the instructions given (see here) and applied the foam to my face (morning and night). It's a rich cream, a bit like a cream cleanser. I left the foam on for 1-2 minutes and removed with a hot cloth. My skin looked a bit red and felt a bit tight (both normal reactions).
Day 2: Still some tightness and redness after use but skin felt really smooth.
Day 3: As above, still some tightness after use.
Day 4: Skin looks brighter, few spots I had on my chin have cleared up.
Day 5: Complexion looking fresher.
Day 6: Pore size looking smaller and skin looks fresh and clean - no oily sheen in T-zone.
Day 7: I'm sold! Skin looks bright and fresh, t-zone oil regulated, smaller pores, less wrinkles around eye area and skin feels rejuvenated.
I'll let you know when I finally finish the soap but I think it's definitely worth a tenner!
