Olay Regenerist is a must have for people 30 and older.  I first took the challenge and tried it on one side of my face for 10 days.  I absolutely noticed a difference.  I use it every night.  I have a defining line on my jaw bone, since i started using regenerist it has reduced the line so much you can hardly see it.  I also have crows feet around my eyes.  Needless to say my crows feet are barely visible.  I would say it has taken 10 years of my looks.  I ran out of it for about 2 weeks and I have to say the lines started coming  back.  So this is something you have to continue to use. ...
