well we have come a very very long way in technology for cleansing the skin and for taking care of our skin. so i have a feeling that if your grandmother used the products available today her skin would look even more young and more beautiful than it did in your eyes. we love our grandmas so they always look beautiful to us. but the newer cleansers are able to get the makeup off our skin without removing our natural oils and sometimes they can even add moisturizers into our skin before we even rinse off. so using the newer products will help your skin look younger and better and will help the products you put on afterwards penetrate more evenly which will be good for your skin as well.
my mom and my grandma had beautiful skin and washed their face with bar soap. why do i need a regimen to clean my face?
