Our mission
Freeing individuals from the constraints of suncare
suncare is the new skincare
Substance Of Light® reinvents the codes and practices in terms of skin protection with innovative products that are easy to integrate into your daily beauty routine.
At the source of Substance Of Light® is light , both vital and yet damaging to the skin. While controlled exposure to the sun is necessary for the synthesis of vitamin D, overexposure can accelerate skin aging and increase the risk of skin cancer.
In addition to the often mentioned UVB and UVA, blue light and air pollution are also harmful. Blue light promotes photoaging and pigmentation, while pollution alters the protective functions of the skin.
With Substance Of Light®, daily sun protection becomes an essential gesture to preserve your health , whether you are indoors or outdoors. However, few people think about reapplying their sunscreen during the day. The fault lies in unsuitable galenics, uninviting textures and formats that are too bulky.
It is to meet this need for high protection, practicality and sensoriality that Substance Of Light® was born.
Founder of Substance Of Light®
Clara Nentille
The story of Substance Of Light® finds its roots in the personal experience of Clara Nentille, founder of the brand. Faced with the devastating effects of skin cancer during her father's multiple operations, Clara witnessed the limits of traditional sun protection.
Drawing on her background in investment banking and her passion for innovation, she founded the brand in 2021 with a clear vision: to create high- performance, sensory and safe solar products.
With unwavering determination and the help of a team of experts, Clara devoted more than two years to developing the patented TRUE FILTER™ formula , tested and reworked dozens of times to achieve uncompromising excellence.
Substance Of Light® embodies Clara's commitment to skin health, providing uncompromising protection for all.
