The effects

Since I’ve only used it for two weeks, I haven’t noticed any improvements in skin tightening. However, I’m happy to report that it does brighten my skin and Mr. G’s, LOL. I gave him some of the serum and his face looks brighter each day. Apart from brightening, my skin feels soft and smooth without having a greasy or sticky finish.
