Blue Light (HEVIS) The Silent Danger from Light

What is blue light?

Blue Light or Blue Light is the official full name as a High Light, the Energy Visible mode (referred to as the HEV or HEVIS Light, ) is a light, high-energy mix in a white light visible to humans. The white light can be divided into 7 colors, violet, blue, green, yellow, red and red, which the blue light is mixed in the indigo and blue with wavelengths between 400-500 nanometers.

The blue light is all around us and can affect our skin unexpectedly. Because it is light that can be found in both sunlight (Like UVA and UVB) from fluorescent lamps. From the phone screen Computer monitor, TV monitor, or from an LED screen Therefore, if anyone thinks sitting in front of a computer Sitting phone In the house or in the office Or use sunscreen on a regular basis, such as general sunscreen that does not protect against HEVIS Light and will be safe from blue light.

Note : In the sun, it consists of about 5% Ultraviolet (UV), which is divided into UVA and UVB, 50% Visible light and 45% Infrared or Infrared.


The effects of UV and HEVIS.

  • Causes free radicals on the skin that stimulate the production of Enzyme, destroying collagen and elastin in the skin, causing skin cells to deteriorate faster than usual Resulting in wrinkles easily Sagging Skin lacking moisture And the skin is older (Photo-aging) followed
  • The study of the research team found that At night, the blue light interferes with the body’s clock circuit, causing the skin to malfunction from what it should be. Then affects the natural regeneration process of the skin Making the skin look finally older Because the blue light is the cause of false perception that it is daytime
  • Stimulate freckles, deep-seated sunblock, dark spots, and dull skin, just like UVA and UVB rays.
  • A 2014 study found that blue light stimulates skin inflammation and leads to dark spots.
