Renouvellance

Managing exposomial photo-stress
for a healthier glow

The holistic insight

Addressing the combined effect of UV rays and pollution

The exposome refers to all the environmental exposure experienced over a lifetime that affects your health. Stressors are often interdependent. For example, recent scientific research has shown that UV rays and pollution have an aggravating effect on each other.

 

This phenomenon is referred to as exposomial photostress. Adopting a holistic approach, we have developed a new active derived from the adaptogens of a red microalga, Porphyridium cruentum.

The bio-Inspired Solution

Leveraging an ultra-efficient photo-synthetic microalgae

To adapt to extreme environments, Porphyridium cruentum implements unique metabolic pathways ; its Phycoerythrin pigment captures green light and enables photosynthesis up to 1m under the water surface, its Exo-Polysaccharides (EPS) protect it from dehydration and environmental stresses.

Using our bio-mimetic cultivation process, we are able to deliver naturally these two bioactives in a unique ingredient, integrating multiple benefits against exposomial photostress ».

The Pathways

Extensive cell protection against photo-stress

In-vitro assays have demonstrated the powerful protective ability of Renouvellance against the damages induced by UV rays (protection from sunburn cells, antioxidant protection, anti-inflammatory action). To take this further, we also explored the protective benefits against the combined effects of UV rays and pollution.

Renouvellance reduces by 88*% the formation of Sunburn Cells (p<0,05)
