Description

【Technical field】 [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to an eye cream containing litchi seed extract and a preparation method thereof. 【Background technique】 [0002] The formation of crow's feet is due to the decline of neuroendocrine function, the decrease of protein synthesis rate, the decrease or loss of the activity of fibroblasts in the dermis, the decrease and fracture of collagen fibers, resulting in decreased skin elasticity, increased wrinkles at the corners of the eyes, and sun exposure, dryness, cold, and face washing. Excessively high water temperature, rich expressions, smoking, etc. lead to a decrease in the elasticity of fibrous tissue. [0003] The so-called "dark circles" are actually divided into two colors, one is cyan dark circles, which is due to the retention of venous blood in capillaries; the other is brown dark circles, which are caused by incomplete melanin production and metabol...
