I had to stop using this product ten days after I commenced.  I started to have an unfavourable reaction to it,  including small then larger acne breakouts around my nose and cheeks, where I have not had any before.  I also got a rash around my mouth!  I stopped using this product a few days ago and already my skin is improving.  I didn't see any brightening effects either.  It may work for others.....Not a good product for me.
