Our mission

Elevating photoprotection to the highest level of expectation, combining scientific performance, sensoriality, and safety against all light sources.

The Genesis

At a very young age, Clara was confronted with the consequences of skin cancer through her father's multiple operations. This foundational experience revealed to her the importance of daily protection and the limitations of traditional sunscreens, which do not protect against the entire harmful light spectrum.

Development

With a background in investment banking and a passion for innovation, Clara founded the brand in 2021 with a clear vision: to design photoprotection products that are at once highly effective, sensorial, and safe.

With unwavering determination and the support of a team of experts, she dedicated nearly three years to developing the urban protective mist (patent pending). Enriched with the TRUE FILTER™ complex, the mist was tested and optimized dozens of times to achieve excellence, without compromise.

Confirmation

Clara launched the urban protective mist for the first time in 2023, and this innovation won numerous awards:

  • Nominated in the “Brands & Retail” category at the Cosmetic360 Awards 2023
  • Awarded in the “Solar Facial Care” category at the 8th INDIES DAYS 2023
  • Winner of “The Beautytank” skincare category at MakeUp in Paris 2024
  • Winner of the “Eure-et-Loir Business Trophy 2024” in the “HOPE” category
  • Awarded the H. Pierantoni Innovation Prize 2025
  • Awarded the “Graine d’Achiever” Prize at the CEW France Achiever Awards 2025 ceremony

    Also winners of Réseau Entreprendre, Réseau Initiative Jeune Entreprise Innovante, and BPI France French Tech
The launch

Substance Of Light® officially launches in 2024. Its first product, the urban protective mist, a patented innovation unprecedented on the market, embodies Clara's commitment to skin health: comprehensive, effective, sensory, and uncompromising protection, designed for all skin types.

The TV segment

Early 2025, Clara will present her project on the set of the show "Qui Veut Être Mon Associé?" on M6, highlighting her mission.

The expansion

True to its mission of making daily photoprotection simple and effective, Substance Of Light® is launching its protective moisturizing fluid: an innovative beauty step that combines high-performance hydration with the most complete light spectrum protection available on the market.
