I would post that I am giving away Aquaphor products to "introduce them more to my campus" on my social medias. Anyone that I contacts me I will share what the pros are of the Aquaphor brand are and how much your skin is cared for when using it. Then give them a product to keep and make sure they share with their friends. I would also go to greek events that my sorority is having and try to see if anyone is interested in learning more or wants to try products. Basically, interacting in ways that can have a snowball effect drawing more people in with every interaction.
