UVMune 400, our Biggest Sun Filtering Technology in 30 Years

Are you sure that your skin is well protected against sun damage? Ultra-long ultraviolet-A (UVA) radiation, which can pass through cloud cover and glass, is one of the chief causes of skin aging and combines with other UVA and UVB rays to contribute to the development of skin cancer. L’Oréal Research & Innovation proudly presents UVMune 400, our first filtering technology to protect skin effectively against ultra-long UVA. Read on to learn how the experts at L’Oréal Research innovated to provide active protection for your skin and tackle a major public health issue.

L'Oréal Research unveils UVMune 400

Depending on the time of day, the season, altitude, and the weather, your skin is more or less exposed to solar radiation and especially to long UVA.These rays reach your skin all year round. Today, L’Oréal is launching UVMune 400, our first filtering technology to protect skin effectively against ultra-long UVA. A new generation of filters has recently been introduced with Mexoryl 400. The Group is now making its biggest breakthrough in solar innovation in 30 years, having succeeded in potentiating the performance and quality of this filter in a unique technology, UVMune 400.

Harnessing Scientific expertise for skin health

Drawing on more than 85 years of experience in sun protection and its unique scientific knowledge of skin, L’Oréal Research has spent decades developing a range of patented filters. In 1982, the Group launched Mexoryl SX, a filter that provides effective protection against short UVA. In 1985, L’Oréal came out with Parsol 1789, the first photostabilization patent, which made it possible to filter long UVA rays up to 360 nm. Then in 1989, it released Mexoryl XL, a filter capable of absorbing UVB and short UVA, while also making other filters more effective.

Ten years of research went into designing Mexoryl 400, making UVMune 400 our first filtering technology to provide effective protection against the 30% of solar UV radiation that was not properly filtered until now, namely ultra-long UVA rays between 380 and 400 nm.

UVMune 400 thus helps preventing the skin from the effects of ultra-long UVA on the skin, which include:

• Oxidative stress ;
• Pigmentation ;
• Modification of genes involved in skin cancer ;
• Immune response disruption ;
• Damage caused by photopollution ;
• Photoaging signs such as wrinkles, loss of skin elasticity, and spots.

This discovery represents L’Oréal’s biggest advance in sun innovation for 30 years and addresses a major public health question, namely how to protect against the deep damage caused by ultra-long UVA rays.
