A New Era for Photoprotection

Pierre Fabre Laboratories’ First Sun Filter | TriAsorB™

The 1980s were a turning point for sun protection with the discovery of the role of UVB rays as a cause of sunburns, the immediate and visible consequence of the harm caused by photo-radiation. Later, in the 1990s, the scientific community demonstrated the dangers of a new type: UVA rays. These rays can penetrate more deeply into the skin and cause greater damage: less visible and identified over the longer term, they are responsible for photo-aging of the skin and skin cancers.

High-energy visible blue light

More recently, new scientific findings have demonstrated the harmful impact of high-energy visible (HEV) blue light on skin cells1-4: it damages cellular components via oxidation mechanisms that lead to skin aging and the development of skin cancers. Located beyond UV rays, high-energy visible blue light penetrates even deeper into the skin than UVA rays: it reaches the hypodermis. It also contains a high quantity of energy, hence its name - high-energy visible blue light – and has been  proven to cause damage to skin cells through sun exposure1-4.

The sun vs. monitors and screens

The blue light from computer monitors and screens cannot be compared to the intensity of the blue light from the sun. This is evidenced by the fact that one can look at a screen for hours, but never directly at the sun. The sun’s light intensity can be up to 1,000 times greater than that of screens5, and one would have to spend close to three months on a phone to have the same exposure as one hour in the sun. Another difference: outside, the skin is exposed directly to the sun while the eye is mainly exposed to radiation diffused by air particles and reflected by surfaces.

By focusing on high-energy visible blue light,
Pierre Fabre Laboratories have taken a major leap forward in photoprotection:



An innovation from 20 years of research


A sun filter inspired by the natural photoprotective properties of melanin...
Melanin naturally provides photoprotection suited to the skin. It provides daily protection from the acute effects of sun rays – sunburns – and also long-term effects – photoaging and skin cancers. Melanin also protects from high-energy visible blue light. Inspired by this unique quality, TriAsorB™ offers the skin ultra-broad and effective photoprotection.

...absorbs and reflects harmful rays

TriAsorB™ is the first organic filter with the unique ability to absorb and reflect the harmful parts of the solar spectrum, which include UVB rays, short UVA rays, long UVA rays and high-energy visible blue light.

...safely protects the skin and respects the environment

The new TriAsorB™ filter is in line with Pierre Fabre Dermo-Cosmétique’s Conscious Care initiative – an effective, reasoned and ethical approach which consists of formulating active ingredients that are respectful of the skin and the environment. TriAsorB™ stays on the surface of the skin, whether it is healthy or damaged6. Tests have proven that it protects DNA from the harm caused by UV stress7 and high-energy visible blue light8.
TriAsorB™ filter has undergone many tests that have proven that it is respectful of marine biodiversity9.


Intense Protect 50+

Suitable for the most sun-sensitive skin11

Intense Protect 50+ is suitable for all skin types, including the most sun-sensitive skin: babies as of 6 months*, children, pregnant women, very light phototypes that lack natural melanin, damaged skin, post-tattoo or skin suffering from the effects of cancer treatments, thanks to its high protection and tolerance properties.

For all types of exposure,
even under extreme conditions

Intense Protect 50+ is suitable for all types of exposure and also the most extreme and demanding conditions for sun protection: high altitudes, high seas, dry climates, humid tropical heat, and nautical sports.
