Premium skincare and hybrid makeup brand Summer Fridays announced on Thursday a strategic growth investment from TSG Consumer Partners (TSG), a leading private equity firm. 

As part of the partnership, previous investor Prelude Growth Partners will exit its investment in the company. Meanwhile, the co-founders of Summer Fridays, Marianna Hewitt and Lauren Ireland, will maintain a significant stake in the company and continue to lead it alongside the current management team.

The new partnership with TSG is expected to support Summer Fridays’ growth initiatives while preserving the core brand and product offerings. TSG will help position the company for continued product development, brand building, and geographic expansion.

“We are thrilled to partner with TSG as we enter this new chapter of growth,” said Hewitt and Ireland. “TSG has an extensive record of growing consumer brands in beauty and can support our expansion with their digital, operational, and consumer insights capabilities. We look forward to accelerating our innovation and global distribution alongside a partner that shares our values and supports our commitment to delivering effortless, gentle options for our customers.”

Founded in 2018, Summer Fridays launched with its now iconic Jet Lag Mask, a hydrating multi-use mask and moisturizer. Over the past six years, the company has expanded its product line to include lip care, suncare, hybrid makeup, and body care.

“Summer Fridays is truly one-of-a-kind in the beauty industry,” added Colin Welch, managing director and head of New York and London Offices at TSG. 

“It is a lifestyle brand that has built unparalleled consumer love through a focus on gently effective, intuitive, and easy-to-use products. We are honored to partner with Marianna, Lauren and the entire Summer Fridays team to build upon the Company’s success and to help further expand the brand globally.”
