Beauty Tips For Body Care
I always see everyone tanning with no abandonment, rarely using sunscreen unless they will be in the sun for hours and yet many people eat healthy diets and live lifestyles that will make them "look younger". Also women that are more conscience of aging never bring up the fake the sun is one of the main reason our skin age yet they buy all sorts of moisturizers. Are people just ill informed or they rather be beach bunnies and choose to ignore the facts, or is it that they know and they just don't care and want to enjoy life?
