Description

Technical Field

[0001] The present invention relates to the technical field of compositions, and in particular to an anti-aging composition and application thereof. Background Art

[0002] With the continuous advancement of science and technology, the scope of electronic devices has become increasingly wide, and people's frequency of use has greatly increased, and these electronic products have increased the burden on the eyes; but due to the inappropriate use of eyes by many people, the burden on the human eye has increased, and the scope of myopia has also expanded year by year.

[0003] At a time when people are paying more and more attention to their own health, protecting their eyes has become a social pursuit. In order to relieve dry eyes and restore their eyesight, people often use eye drops or eye drops, but most of these eye drops or eye drops contain various preservatives, hormones, antibiotics, anti-inflammatory and other components. These components will not cause damage to the eyes when used in small amounts, but long-term use may cause eye discomfort. At the same time, most of the eye drops currently available on the market have relatively single functions and are difficult to meet people's needs.

[0004] In view of this, the present invention is proposed. Summary of the invention
