Problems solved by technology

[0006] 1. It does not reflect the safety of the sunscreen itself: Among the sunscreens approved by the governments of various countries, many sunscreens have been found to have photoinstability in the application research, and the photolysis products are likely to cause skin phototoxicity, and this Aspects cannot be fully evaluated through SPF and PA values
[0007] 2. Cannot fully reflect the internal damage of ultraviolet rays to the skin: no matter what kind of sunscreen and combination of sunscreens are used, it is difficult to avoid one-sided blocking of ultraviolet rays in a certain area. Although it has certain effects in preventing sunburn and redness, but Harmful UV rays cannot be completely blocked from entering the skin, and unblocked UV rays can still cause chronic damage to skin cells
[0008] 3. The long-term damage of ultraviolet rays to skin cells, especially DNA, cannot be evaluated by SPF and PA
[0009] Due to the limitations of sunscreen evaluation methods, sunscreen products on the market generally have limitations in sunscreen function

The invention further relates to the preparation method of the composition. The composition disclosed by the invention is prepared based on the principle of the harm of ultraviolet rays to human bodies, has the characteristics of light stability and broad spectrum sunscreen, can improve ultraviolet ray immunity of skin, and can prevent the ultraviolet rays from hurting the human bodies more comprehensively.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular, the invention relates to a sunscreen composition and a preparation method thereof. Background technique [0002] The earth on which human beings live, due to the protection of the atmospheric ozone layer, blocks 99% of the ultraviolet radiation in the sun, so that all creatures on the earth are protected from strong ultraviolet rays. However, with the development of industrial civilization, the ozone layer has been greatly damaged, which has greatly increased the ultraviolet rays irradiated on the earth's surface and posed a serious threat to human health. The research and reports that ultraviolet rays cause premature skin aging and even skin cancer have long been commonplace in western developed countries, and have been widely known and accepted by ordinary people. Some people think that yellow people are not as prone to sunburn as western white people, but Japanese research reports show...
