Job description

Join L'Oréal: As the #1 beauty company in the world with 40+ brands - CeraVe, Kiehl's, Maybelline, Prada Beauty, and Redken, to name a few - we embrace diversity, sustainability, innovation, and well-being to help you shape the future of beauty.
The L'Oréal USA Summer Internship Program is a paid, 11-week experience. You won't just observe - you'll be fully integrated into a brand marketing team, own real day-to-day responsibilities, and lead your own individual strategic project that you'll pitch directly to senior leadership. Past interns have seen their ideas move from a deck into real-world execution - that's the kind of ownership you'll get here.
Applications reviewed on a rolling basis, August 14 - September 30, 2026. We welcome students of all backgrounds, including race, ethnicity, gender expression, LGBTQ+ status, military status, and disability status, to apply.
Who You Are
  • Ambitious students currently enrolled in a 4-year college or university who are expected to graduate between December 2027- July 2028

    • Minimum 3.5 GPA
    • Willing to relocate to one of our U.S. internship hubs: New York, NY

Areas of Digital You Could Work In
Depending on your brand and team placement, you may gain hands-on exposure to:
  • E-Commerce Strategy - optimizing the digital shelf across Amazon, TikTok Shop, Sephora.com, and DTC sites
  • Performance Marketing & Media - planning and analyzing paid social, search, and programmatic campaigns
  • Social Media & Community Management - managing brand presence and engagement across TikTok, Instagram, and emerging platforms
  • Influencer & Creator Partnerships - sourcing and activating creators to drive authentic digital reach
  • Marketing Analytics & MarTech - using tools like GA4, Salesforce, and internal dashboards to measure digital campaign performance and ROI
  • CRM & Personalization - supporting email, loyalty, and personalized consumer journeys
  • Content & Digital Creative - producing short-form video and digital-first creative assets
  • SEO & Digital Discovery - improving how consumers find brands and products online

(Note: if you're more interested in traditional brand marketing, check out our Marketing Summer Internship track instead.)
What You'll Do
  • Own day-to-day digital or e-commerce responsibilities - from consumer insights to campaign execution - on one of our 40+ brands
  • Lead your own strategic project from insight to recommendation, presented directly to senior leaders
  • Collaborate cross-functionally with Digital, Supply Chain, Finance, R&I, and Sales to see how each function shapes a brand's business
  • Build real business acumen by working alongside brand managers in the beauty industry
  • Sharpen your presentation, analytics, leadership, and strategic thinking skills - skills that carry into any career
  • Placement on a marketing team within one of L'Oréal's four divisions: Consumer Products, Luxury Products, Dermatological Beauty, or Professional Products

The Program:
  • This is a paid internship opportunity. Housing assistance is provided on an individual basis based on eligibility per our L'Oréal Relocation Policy.
