What is blue light ?

We know blue light emitted by artificial sources with LED or compact fluorescent lamps (CFL) such as computer screens, smartphones, etc. But did you know blue light is mainly emitted by the sun?
The luminous intensity of the sun can be 1000 times greater than that of screens and you would have to spend 64 full days in front of your digital tablet for an exposure equivalent to one hour in the sun.

It is therefore necessary to protect your skin against blue light emitted from the sun.

Understanding blue light and its effects

« Violet blue » light is the band of the visible spectrum containing the most energy, hence its name HEV (High Energy Visible Light), which is harmful to the skin: it accelerates skin aging, and it is necessary to protect ourselves from it.

25% of skin damages are caused by blue light*. Its radiation accelerates skin ageing every day and promotes the appearance of wrinkles and blemishes.

It is therefore reasonable to assume that in the long term, and especially as ageing erodes the skin’s natural defence mechanisms, exposure of the skin to high-energy light can have a harmful effect that promotes ageing and even cancer mechanisms. Moreover, blue light acts on the pigmentation gene and stimulates the activity of melanocytes. It therefore accelerates certain skin conditions linked to the functioning of melanin such as pregnancy mask or hyperpigmentation. Blue light therefore has potentially even more harmful effects than UVA, especially on darker skin.

With visible high-energy blue light, a new enemy of the skin has been discovered, perhaps even more harmful than UVA and UVB. These damaging waves penetrate even deeper into the skin, even into the hypodermis. With its intense energy - which gives it its name - blue light attacks the skin. Blue Light can be harmful for the skin within an hour of exposure to the sun². Other studies have also shown that this blue-violet light leads to the formation of toxic reactive oxygen species that affect all the constituents of the skin.

The 1st ultra-wide spectrum organic solar filter*

Short UVB UVA
Long UVA
Blue light up to 450nm

Our best prevention against skin photoaging

Resulting from Pierre Fabre medical research and revealed in 2020 via the launch Intense Protect 50+, TriAsorB™ has extended the foundations of photoprotection by offering an ultra-broad spectrum sun protection against UVB - short UVA - long UVA, and beyond UV, up to 450 nm, against blue light, which has been proven to accelerate skin ageing.

Integrated into the patented Eau Thermale Avène filtering system, TriAsorB™ enhances the skin's level of protection against blue light related photoaging and thus offers ultra-broad sun protection and helps prevent deep, visible skin damage.

Eau Thermale Avène's innovation against blue light: the new TriAsorb™ sun filter

To fight the effects of blue light on the skin, Eau Thermale Avène Laboratories have developed a revolutionary new technology: the TriAsorb filter, inspired by the natural photoprotective power of melanin.

How does it work in practice?

Melanin, which is a function of each individual's phototype, is responsible for naturally providing the skin with the right photoprotection. It protects against the acute effects of the sun's rays on a daily basis - like sunburn - but also against the long-term effects, like photoageing and skin cancers. It also protects against blue high-energy visible light. Inspired by this unique function, TriAsorB™ provides the skin with very broad and effective photoprotection and reflects the harmful part of the solar spectrum, which includes UVB, short UVA, long UVA, but also blue high energy visible light.

A safe formula

The new TriAsorB™ filter is an organic molecule that has been spread through the formula. The technique used to add the filter guarantees its safety. Thanks to TriAsorB™, we have achieved the feat of reducing the proportion of filters in the new Intense Protect 50+3 by about 10% while maintaining high quality protection.

Four years of work and 30 toxicology studies were carried out to prove the filter’s safety. The ultra safe TriAsorB™ filter stays on the surface of the skin, whether skin is healthy or thirsty.

3 Tests show evidence that the filter protects cellular DNA from damage due to UV stress.4

Respect for the environment

Eau Thermale Avène Laboratories continues with its environmentally responsible approach and commitment to limit the impact of sun filters on the oceans. The new TriAsorB™ filter has passed numerous tests under experimental conditions which proved that it was non-toxic on 3 key species of marine biodiversity: one coral species, one phytoplankton species and one zooplankton species.
