The skin is the largest organ of the human body, which prevents damage from the external environment, such as ultraviolet rays, pathogenic bacteria, and external force damage. The skin also has the functions of preventing moisture loss and keeping warm. The skin is divided into epidermis, dermis and subcutaneous tissue from the outside to the inside.

The skin is rich in extracellular matrix (ECM) such as collagen and hyaluronic acid (commonly known as hyaluronic acid), which gives the skin elasticity, moisture retention, surface luster, and structure to support the skin. However, with age and the influence of the external environment, the ability of skin cells to secrete extracellular matrix decreases. At the same time, these extracellular matrix are degraded by collagenase and hyaluronidase (Hyaluronidase, HYAL), resulting in collagen and Hyaluronic acid is lost, the skin barrier is damaged and the structure is loose, resulting in wrinkles, depressions, sagging, thinning, dryness, reduced water retention, fragility and irritation, and other skin aging phenomena.

In recent years, people have paid more and more attention to skin care issues. There are many types of products, and some skin care products contain synthetic chemical substances. These ingredients may irritate the skin and even cause damage to health after long-term use. In addition, there are some oral or smeared collagen and hyaluronic acid products. However, oral supplementation of collagen or hyaluronic acid will be used by the body after being broken down and absorbed by the digestive tract, and will not be completely stored in the skin. Its effect Limited; the collagen or hyaluronic acid applied to the skin is difficult to be absorbed by the skin due to its too large molecular weight, and it is not easy to stay on the skin.

Next, specific embodiments of the present invention will be described, but the present invention is not particularly limited to these embodiments.

Example 1 Preparation method of Gac oil of the present invention

The Gac oil of the present invention is prepared by squeezing the arils of the Momordica cochinchinensis Spreng. Firstly, the fresh cockleshell fruit is cut open, the cockleshell fruit seeds are taken out, and the aril is peeled off; then, it is dried at 60°C for 24 to 48 hours; and roasted in a roasting pan at 80°C for 10 minutes. Finally, an industrial-grade screw extruder is used to squeeze out the oil, and the supernatant is centrifuged to obtain the Momordica charantia oil used in the preparation of the skin-improving composition of the present invention.

Example 2 The Gac oil of the present invention enhances the effect of keratinocytes in the skin to synthesize Type I procollagen

The following Examples 2 to 4 used HaCaT cells, a cell line of keratinocytes in the epidermal layer of human skin, for analysis.

It is known that collagen is the protein with the highest content in the human body. In skin tissues, both the epidermal layer and the dermis layer contain a large amount of collagen, which is an important component of the extracellular matrix. It is produced and secreted by skin cells. Between cells. Collagen can maintain skin elasticity and has a high affinity with water molecules, so it has a good moisturizing function. Collagen accounts for about 70% to 80% of the dry weight of human skin, which can support the overall structure of the dermis and make the skin plump without wrinkles. Among them, Type I collagen (Type I collagen) accounts for the majority of human skin tissues, about 85%~90%; followed by Type III collagen (Type III collagen), about 10%-15%.

The collagen in the skin will decrease with age, bad habits or the influence of the external environment, resulting in a decrease in biosynthesis and an increase in decomposition, resulting in a gradual loss of collagen, resulting in the disintegration of the skin structure and the decrease in thickness, which ultimately leads to the formation of wrinkles , It loses the elasticity of the skin, so it is very important to supplement and restore the collagen content in the skin, which is very important for skin health, reducing wrinkles, anti-UV damage and anti-aging.

The type 1 collagen is derived from the synthesis of type 1 procollagen by cells. Therefore, the present invention is to detect the effect of cochineal fruit oil on the synthesis of type 1 procollagen by skin keratinocytes.

The experimental results of the effect of the cochinchinensis oil of the present invention in enhancing the synthesis of type 1 procollagen in human skin keratinocytes are shown in Fig. 1. The blank control group without cochinchinensis oil treatment, the human skin keratinocytes The concentration of type I procollagen in human skin is less than 10ng/mL; the experimental group treated with a 0.01μg/mL cochinchinensis oil, the concentration of type I procollagen in human skin keratinocytes is also less than 10ng/mL; In the experimental group treated with cochinchinensis oil at a concentration of 0.1μg/mL and 1μg/mL, the concentration of type I procollagen in human skin keratinocytes was about 10-20ng/mL; at a concentration of 10μg/mL In the experimental group treated with Momordica charantia oil, the concentration of type I procollagen in human skin keratinocytes was about 30-40ng/mL; the experimental group treated with Momordica charantia oil at a concentration of 50μg/mL, human skin keratin The concentration of type I procollagen in the producing cells is at least 40ng/mL; and the experimental group treated with a concentration of 100μg/mL of Momordica charantia oil, the concentration of type I procollagen in the human skin keratinocytes is at least 10ng/mL .

Therefore, human skin keratinocytes treated with cochinchinensis oil at a concentration of 0.1~100μg/mL have the effect of stimulating the synthesis of type 1 procollagen, compared with the blank control group not treated with cochinchinensis oil. Especially at a concentration of 50μg/mL cochinchinensis fruit oil, the effect of promoting synthesis is better.
