Blue light skin care ingredients from Rahn

It is well understood that UV-B and UV-A radiation can damage DNA and proteins, leading to accelerated skin ageing.

More and more attention is being paid to the contribution visible light makes to skin ageing.

The most deleterious fraction of visible light is so-called "high energy visible light" (HEV) or blue light, flanking the UV spectrum.

Although most blue light is contained in daylight, typical artificial emitters of blue light are lamps and the screens of laptops, tablets and smart phones.

The irradiation of skin with blue light increases the reactive oxygen species (ROS) load of the cells, resulting in oxidative stress with subsequent damage:

Cells lose its capability to cope with other all-day impacts that drive premature skin ageing, which is associated with symptoms like hyperpigmentation, wrinkle formation and loss of elasticity and firmness. Adequate protection against the consequences of blue light irradiation of skin is therefore essential for a healthy, youthful complexion and it should be part of any modern skin care product.

RAHN has tested a selection of three RAHN-Cosmetic Actives for its blue light protection index and recommends:

  • CELLIGENT UV / HEV protection for DNA, cell and stem cell and rapid regeneration of UV-damaged skin.
  • MYRAMAZE Cell membrane safety guard and blue light protection for stressed, fragile skin.
  • PROTEOLEA Cellular recycling manager plus anti-blue light formula for a 6-year skin rejuvenation effect in just 4 weeks.
