I find that when I smile I look younger. I think there has been some research that indicates people with a "pleasant" dosposition live longer.
Really, I actually don't smile to look younger because smiling can lead to crow's feet and wrinkles. I think part of the reason why I look younger than most people (I'm talking about no wrinkles in my skin) is cause I never smile where people who smile are more likely to get laugh lines.
Other things I do to look younger :
Use retinol cream at night (Green cream) alternated with Mama lotion
Use Skinceuticals CE Ferulic acid with sunscreen on top everyday (either Neutrogena or La Roche Posay)
Use an anti oxidant cream on top of the CE ferulic serum (clinique antioxidant cream)
exercise moderately
eating healthy, well I try but once in a while I do slip and end up eating some bad foods like In N Out burgers or pizza etc
Thats kinda sad.....
Jackie smile!!!!....it takes more muscles to frown than to smile. Smile lines let me know that I've lived a good, healthy, fun life. I also believe that smiling makes you look younger. When you think of young (or at least when I do) you think of laughter and smiling. Plus you have better immunity if you laugh more.
