Tyra Banks swears by vaseline. She says this is her ultimate beauty secret (yeah right) also I remember their being talk that Marilyn Monroe put vaseline on her face to make her skin look dewey so people might use it for this reason
I used to put Palmer's cocoa butter on my face as a teen. for awhile I used to have a lot of blackheads on my nose and never knew why..I discovered that the cream was too thick and was clogging my pores. After I stopped using it the blackheads on my nose went away
