I have been using this product for years, and I am 66 years old. I put it on in the morning and it lasts all day, although I do reapply after a few hours when I'm at the beach. My dermatologist told me that whatever I use on my face, to use on my chest also. When I told her that I use Eucerin SPF 30 Daily Protection, she said that that is a good product. I also use it on my neck and ears and on top of my hands. Most people don't know that Eucerin makes a Daily Protection sunscreen. But OH YES they do and it is fantastic! At first it has a shine on your face after applying, but absorbs in after a little while.
