Description

Anti-photoaging skin care composition and preparation method and application thereof
Technical Field
The invention relates to the technical field of cosmetics, in particular to an anti-photoaging skin care composition, a preparation method and application thereof.
Background
Aging, also known as aging, is a process by which organisms lose and deteriorate from constituent substances, tissue structures to physiological functions over time or age, and gradually tend to die, and is a complex and irreversible natural phenomenon. Skin aging is a direct manifestation of body aging, and is mainly characterized by wrinkling, dry skin, atrophy, loss of elasticity and the like. The skin is gradually aged along with time and seriously influences the life quality of people under the influence of external environmental factors such as endogenous aging of the organism, ultraviolet rays, environmental pollution and the like.
Ultraviolet rays are divided into three wave bands, wherein short wave ultraviolet UVC is absorbed by the atmosphere and cannot reach the ground, and part of medium wave ultraviolet UVB and almost all long wave ultraviolet UVA can penetrate the atmosphere to reach the ground. UVB energy is strong, the penetrating power is weak, and the UVB energy mainly damages epidermal cells, damages skin barrier and inhibits immunity, thereby causing erythema and pigmentation. UVA energy is weaker, but penetration is stronger, and can reach dermis to damage collagen, elastic fiber and proteoglycan of dermis. Skin photoaging is the result of UVB co-acting with UVA. Photoaging is mainly manifested by skin sagging, roughness, increased wrinkles, irregular pigmentation, vasodilation, hypoparagonism, and abnormal proliferation of the epidermis in the exposed areas. From the analysis of microstructure and biological indexes, the content of Collagen, collagen fibers and elastic fibers is remarkably reduced after ultraviolet irradiation, wherein the Collagen IV is the main protein of the junction of the dermis (DEJ region), and the skin wrinkles are generated due to the reduction of the related effect of the dermis after the content of the Collagen IV is reduced. The elastic fiber is composed of microfibril and elastin, has elasticity but poor toughness, and the elastic fiber and the collagen fiber are mutually crosslinked, so that the elasticity and toughness of the skin are maintained. Therefore, the synthesis of the Collagen IV and elastic fiber is promoted, and the anti-photoaging effect can be achieved, so that the anti-aging effect is achieved.
In order to resist skin photoaging, not only are more and more effective ingredients sought and developed, but also how to apply the effective ingredients to cosmetics needs to be studied, so that the skin health state of the public is truly improved.

As can be seen from table 8, the NC group had significantly lower elastic fiber content than the BC group, indicating that the test stimulation conditions were effective. Compared with the NC group, the elastic fiber content of the PC group is obviously increased, which proves that the positive control of the test is effective. The elastic fiber contents of examples 1 to 6 and comparative example 1 were significantly increased, and the elastic fiber contents of comparative examples 2 to 5 were not significantly changed, as compared with NC groups. Examples 1-5 are compared with comparative examples 1-4, which demonstrate that sodium hyaluronate-ferulic acid grafts significantly promote the formation of elastic fibers, and that sodium hyaluronate-ferulic acid grafts have synergistic effects with one or both of viola diffusa extract and calendula extract, and that one or both of viola diffusa extract and calendula extract alone does not have the effect of promoting the formation of elastic fibers. Example 6 comparative example 5 demonstrates that cosmetics containing the photoaging-resistant composition have a remarkable effect of promoting the generation of elastic fibers. The anti-photoaging composition and the cosmetic containing the same can achieve effective photoaging resistance by promoting the synthesis of elastic fibers.

( And (3) injection: # represents p <0.01 compared to the blank; * Represents p <0.01 compared to negative control; * Represents 0.01< p <0.05 compared to the negative control. )
As can be seen from table 9, the Collagen IV in NC group was significantly reduced compared to BC group, indicating that the stimulation conditions of this test were effective. The Collagen IV in the PC group increased significantly compared to the NC group, indicating that the positive control of this test was valid. The Collagen IV of examples 1-6, comparative example 1 were significantly elevated compared to NC groups, and the Collagen IV of comparative examples 2-5 were not significantly altered. Examples 1-5 are compared with comparative examples 1-4, demonstrating that sodium hyaluronate-ferulic acid grafts significantly promote the production of Collagen IV, and that sodium hyaluronate-ferulic acid grafts synergistically act with one or both of viola diffusa extract and calendula extract, and that one or both of viola diffusa extract and calendula extract alone does not promote the production of Collagen IV.
