Dans Ma Peau : When sun meets skin
In a survey carried out by Yougov in 2019, only 2 out of 5 people said they protected themselves when out in the sun. Yet it is a danger that goes beyond a case of sunburn. As damage to skin by the sun’s rays is wide-ranging in nature, a sun-block needs to protect people against both UVA and UVB rays. UVBs carry more energy and affect the surface of the skin, causing sunburn in the short term and skins cancers, including melanomas, in the longer term. The UVAs have less energy but penetrate deeper, to the sub-cutaneous layers, causing the premature ageing of the skin and contributing to the increased incidence of skin cancer. And 95% of the sun’s rays are UVAs!
Innovate, for better protection
In 1935, Eugène Schueller, our Group’s founder, was already aware of the importance of being protected from the sun. He developed the iconic Ambre Solaire at a time when the first paid holidays for employees were being introduced. His product was a world first. A high-quality sun filter, with an odor that was easily recognizable and a pleasant feel to the touch… the same criteria that guide our Research and Innovation teams today. “The challenge is to encourage consumers to protect themselves, whatever their situation in life, by applying products that are pleasant to use,” explains Nathalie Jager-Lezer, International Director of Photoprotection Innovation at L’Oréal Research & Innovation.
When it comes to the sun, research never stops. Our aim is to keep improving sun protection, on the one hand by discovering and patenting new filters, and on the other by refining the formulation or presentation of our products. Whether in mist or spray form, the objective is to ensure an even, lasting and pleasant distribution of the product on the skin to provide optimal protection.
Recreating sun rays and reconstructing the skin: Innovations that help our skin
To support our innovation programs for sun protection, we have equipped ourselves with leading-edge technologies that add to our expertise.
To understand and to test our products, our Research & Innovation teams are particularly working with solar simulators. These are able to recreate the sun’s effects and its UV emissions in very precise locations on the planet, according to the time of day or period of the year. Such technology enables us to develop and market products that are equally effective in France as they would be in countries like Sweden, Chile or Senegal.
