What secret to the beautiful glowing skin of people in Vietnam?  

I believe it's a healthy diet and exercise. I can see most people in Vietnam being very healthy. At least the majority of people I met from Vietnam, they all seem to be very healthy. They don't understand America's poor dietary habits. 

I wouldn't doubt they have some creams and eat certain healthy foods that help make the skin glow. I certainly wish I had health like that. 

I think it is not the skin but the heart as well and the food which makes them beaut

maybe it's because of the environment and the food the affects the most.

healthy life and environment thats all.

why would we tell you our secret if you know it you will become pretty like us ;).

applying facemask using facewash twice a day and taking stream two or three times in a week. the major factor is the environment

maybe it is natural

I think this is because of the healthy weather, and the people born with that quality. When I was an essay writer, I searched a lot about them. And most of the result stated that this is because of the existing weather of Vietnam.
