Diet (sugar, dairy, wheat), exercise, sleep, hydration, sunblock, genetics...it all plays a part. Develop good "life" habits and you will see the results in the mirror.
Start slow with small steps. For instance, make a point to drink one more glass of water daily. Sleep one half-hour longer. Drink three less coffees a week. Eat dessert only on weekends.
And last but not least...smile. On the Souli Skinspa Facebook page, a lot of folks were commenting on how beautiful a client of mine looked. Her response? "It was the SMILE that made the difference." Such a great reminder!
