Founded 2000 in London by Rob Calcraft and Antony Buck. 'REN' is Swedish for 'clean' — the brand was built around the founders' search for skincare without synthetic fragrance, sulfates or known irritants, well before clean beauty was a recognised category.
Evercalm became the sensitive-skin hero. Ready Steady Glow Daily AHA Tonic became the second-hero — a daily exfoliant that earned its place against The Ordinary and Pixi at a premium tier.
Acquired by Unilever in 2015, with a global sustainability commitment that includes 100% recyclable packaging. The brand sits in MECCA's clean-skincare tier with stronger active credibility than Farmacy or Youth To The People.
