I was casually watching a fairly long ad while waiting for the real promgramme that I was taping and saw something that interested me, so I went back to check the ad later and realized what that was. In the before and after pictures, there looks to me to be no real difference at all between the people depicted – apart from one thing. In the after shots, they’re smiling widely and the lighting appears to be better. So that’s the trick to self-improvement? Smile widely and make sure you’re in the light.
