Can blue light cause skin damage?

There is scientific evidence that visible light, especially that of the blue-violet spectrum (wavelengths between 400 -500 nm), emitted by the sun, electronic device screens and some LED lamps, can cause spots, solar erythema and premature skin aging. It is important to mention that scientific studies on the effects of blue light on the skin are still very scarce, compared to those that already exist on ultraviolet light or even on infrared light.

It is known that blue light contributes to increased production of free radicals that damage DNA and accelerate the degradation of extracellular matrix components, such as collagen, adding to the fact that blue light potentiates the harmful effects of ultraviolet and infrared radiation.

How can we protect ourselves from blue light?

We want to make it clear that a sunscreen may not protect against blue light, if it does, it will be mentioned on the package. Therefore, it is essential to use antioxidant products as a complement to daily sunscreen, as they will act in synergy to protect the skin from the harmful effects of the various types of radiation that can affect our skin.

These antioxidants can be used orally, as Polypodium leucotomos supplements, or used topically, as serums with Vitamin C, Vitamin E, or Ferulic Acid.

Antioxidant serums should be applied in the morning before your moisturizer, followed by sunscreen. Here are some Inouïe suggestions for antioxidant serums:

1 Oskia Renaissance Brightlight Serum (serum with Vitamin C, E and Glutathione)

2 Pestle & Mortar Vitamin C 2 Phase Serum (serum with 3 types of vitamin C, for a total of 16%)

3 Skintegra Superba C (serum with Vitamin C and E and ferulic acid)

4 Alpha-H Vitamin E (serum with Vitamin E)
