Olvara published an article in the Olvara Journal examining fragrance rejection and skin chemistry.

Olvara is a personal fragrance intelligence platform built around a simple idea: fragrance should be understood through the person wearing it, not only through ingredients, notes or popularity. Olvara learns from individual taste, fragrance experience and real-world feedback to help people understand which fragrances are likely to suit them, explore their collection, discover new possibilities and make more confident fragrance choices. The platform brings together fragrance knowledge, personalization and artificial intelligence while keeping human preference at the centre. Features including Scan, Passport, Cabinet and Layer are designed to make fragrance discovery increasingly personal as Olvara learns. Olvara was founded by René and Bouchra, combining technology, product development, commercial experience and fragrance expertise.
