Amorepacific Publishes Paper on Clinical Evaluation Method for Blue Light Blocking

[Asia Economy Reporter Yujin Cho] Amorepacific announced on the 27th that a paper from its Technology Research Institute's Anti-Pollution Research Center, covering studies on confirming the skin hazards of blue light, developing clinical devices, and verifying the efficacy of blockers, was published in the SCI-level international journal, the Journal of Cosmetic Dermatology.

Blue light is a blue wavelength light existing between 380 and 500 nm (nanometers). It has the shortest wavelength and strongest energy among visible light, and prolonged exposure is known to cause sleep disturbances and vision damage.

Although it also adversely affects the skin, such as pigmentation, decreased elasticity, and moisture loss, there has been no clinical research specifically verifying the harmful effects of daily blue light exposure on the skin.

Jongri Cho, lead researcher at Amorepacific Technology Research Institute's Anti-Pollution Research Center, identified the harmful blue light wavelengths for the skin and developed a device capable of performing clinical evaluations of blue light blockers at those wavelengths.

The newly developed device by Amorepacific replicates the blue light wavelength range frequently exposed to modern people due to artificial lighting such as smartphones and TVs. It also precisely controls the intensity and duration of light, facilitating clinical evaluations of skin damage that may occur from blue light in daily life.

Through experiments using this clinical device, Amorepacific Technology Research Institute revealed that blue light at a wavelength of 456 nm causes skin pigmentation. Based on this, they tested whether the blue light blockers developed and released by Amorepacific can actually prevent skin pigmentation, and proved the product's blue light blocking effect through measurements such as changes in melanin index.

Since 2017, Amorepacific Technology Research Institute has been studying the skin hazards of blue light. Notably, the research achievements on the world's first developed clinical evaluation method for blue light blocking were also presented at the International Federation of Societies of Cosmetic Chemists (IFSCC) held in Munich, Germany, in 2018.

Based on these research results, Amorepacific Technology Research Institute's Anti-Pollution Research Center has verified and applied blue light blocking and damage mitigation effects in several products, including Sulwhasoo Sangbaek Cream, Hera Sun Mate Excellence, IOPE UV Shield Sun Anti-Pollution, Laneige Radian-C Cream, and Laneige Neo Cushion.
