Composition for preventing blue light and repairing blue light damage

Abstract

The invention provides a composition for preventing blue light and repairing blue light damage, including titanium dioxide and a composition for repairing blue light damage. The Blue Light Damage Repair Composition includes Cranberry Extract, Withania Root Extract, Mediterranean Cypress Leaf Extract and Mugwort Leaf Extract. The composition of the present invention can not only resist scattering blue light, reduce the transmittance of blue light, but also repair mitochondrial DNA damage caused by blue light, reduce free radicals generated under blue light irradiation; meanwhile, it can also solve pigmentation and skin aging caused by blue light The problem.

Description

technical field [0001] The invention belongs to the field of cosmetics, and particularly relates to a composition for preventing blue light and repairing blue light damage. Background of the Invention [0002] Blue light is visible light with a wavelength of 400-500nm, which is the shortest wavelength of visible light, also known as High Energy Visible Light (HEVL). Blue light has strong penetrating power and can penetrate the epidermis and dermis of the skin. Floor. Blue light mainly comes from natural light, LED lights, and electronic devices such as mobile phones and computers. Studies have shown that blue light is related to sleep disorders, and can also lead to eye fatigue and even visual impairment. In 2005, Bernard first reported the damage of blue light to the skin, causing mitochondrial DNA damage and generating free radicals, thereby causing skin pigmentation and skin. Ageing.

Problems solved by technology

[0003] Chinese patent application CN109464508A discloses a traditional Chinese medicine composition for repairing damage caused by blue light. The composition is prepared from ramie, peach blossom, white peony root and licorice. Objects cannot block scattered blue light

[0004] Chinese patent application CN109077952A discloses an anti-blue light air cushion CC cream, which contains ultraviolet absorbers, Antarctic ice sea brown algae extract, and Chinese kiwi fruit extract, which can block the scattered blue light and have certain repairing functions, but cannot Reduce the damage of blue light to mitochondria and free radicals, and can not improve the problem of pigmentation

[0005] Chinese patent application CN109394566A discloses a mask essence for repairing blue light damage, but its composition is complex, although it has a repairing effect on the skin after blue light irradiation, it still does not have the effect of blocking blue light

[0006] In the current research, there are few ways to alleviate the damage of blue light to the skin from the two aspects of preventing blue light and repairing blue light. There is no suitable skin care for mitochondrial DNA damage, weakened free radical scavenging ability, pigmentation and skin aging caused by blue light. Taste
