Description

Technical Field

[0001] The invention relates to the technical field of skin anti-aging and repairing, and in particular to a skin repairing and anti-aging cream and a preparation method thereof. Background Art

[0002] Skin aging is mainly manifested in two aspects: first, the skin gradually loses its elasticity and forms wrinkles; second, various spots such as chloasma and age spots gradually appear on the skin surface. According to the free radical theory of aging, free radical damage to the skin is an important factor in the process of skin aging. The free radicals produced in the body react with fatty acids to generate substances such as malondialdehyde, which react with proteins on the cell membrane to form lipofuscin, which is deposited on the skin and becomes various spots. Free radicals can also cause the collagen fibers in the epidermis to lose elasticity due to cross-linking, denaturation and brittleness of elastic fibers. When the skin lacks moisture, it is easy to cause the elastic fibers to break and form wrinkles. Therefore, free radicals have a great damaging effect on the skin. If effective measures can be taken to reduce the generation of free radicals in the skin, remove the free radicals that have been generated, and maintain skin moisture, aging can be effectively slowed down and the deposited pigments can be diluted, thereby achieving skin repair.

[0003] Hyaluronic acid is an important skin moisturizer, but existing studies have shown that the effects of using hyaluronic acid for skin anti-aging and repair are not ideal.

[0004] Therefore, providing a highly effective skin anti-aging and repair product is a current research hotspot. Summary of the invention
