Summer Fridays is a creator-founded skincare brand launched in 2018 by Marianna Hewitt and Lauren Ireland. The brand is celebrated for its minimalist aesthetic, transparent ingredients, and focus on clean, effective skincare essentials. Their debut product — the Jet Lag Mask — became a viral success, selling out repeatedly and cementing Summer Fridays as a leader in the modern clean-beauty movement. The brand has since expanded into a full range of skincare and body products available at Sephora, Mecca, and Cult Beauty. Summer Fridays is self-funded and privately owned, operating as a hybrid of influencer-led storytelling and traditional luxury skincare innovation.
