To share 300 Aquaphor products within a college campus, I'd use social media strategically. First, I'd run a giveaway contest on popular platforms like Instagram and Twitter, encouraging students to follow, like, and share posts for a chance to win a product. I'd also collaborate with influential campus figures to review and endorse the products. Next, I'd create engaging content, including skincare tips and testimonials, to share on the college's official social media accounts. Additionally, I'd set up sampling stations at campus events, ensuring students can try the products firsthand. Lastly, I'd use Instagram Stories and Facebook Events to promote any on-campus product launch events, generating buzz and curiosity.
