The active ingredients in Ginseng extract, ginsenosides, exist not only in the roots, but also in the stems and leaves of ginseng. Therefore, ginseng extracts extracted from ginseng stems, leaves or roots have skin care effects, and they are widely used in the cosmetics industry. They have long been added to cosmetics as antioxidants, skin conditioners and scalp conditioners. Ginseng extract is found in major skin care brands.
Ginseng extract powder
Ginseng is a traditional precious Chinese medicinal material in my country, and it has always been a research hotspot in the field of medicine at home and abroad. At the same time, ginseng is also a rare beauty product. “Compendium of Materia Medica” once recorded that ginseng can stay in the face and get rid of old age, and it is the elixir of keeping youth in the face.
Ginseng (Panax ginseng C.A Meyer) has been used as a medicinal plant for more than 4,000 years and has been regarded as a superior nutritional tonic since ancient times. Ginsenosides are the main active components of ginseng. Most of the research on ginsenosides at home and abroad focuses on ginseng roots; however, many research reports in recent years have shown that the content of ginsenosides in ginseng stems and leaves is higher than that in roots, and the leaves contain a large amount of ginsenosides. ginsenoside Rb3 (about 55.72%), while the root contains more ginsenosides Rb1 and Rc. In addition, Rb3 was only detected in leaves.
Ginseng is known as the medicine of “immortality” in medical treatment and health care. In cosmetics, it can promote smooth and soft skin. It has a good effect on the prevention and treatment of facial acne, acne scars and brown spots. It can prevent hair loss, white hair and improve the The suppleness and brittleness of the hair are improved, and the tensile strength and ductility of the hair are improved.
Anti-aging, anti-ultraviolet, reduce wrinkles, maintain skin moisture, rejuvenate, prevent hair loss, white hair, balance skin metabolism, prevent dandruff, prevent chapped, moisturizing skin.
Research on the effect of ginseng on skin whitening
Ginseng contains ginsenosides, essential oils, ginseng acid, vitamins, etc., which can promote skin metabolism and delay aging. The mechanism of action is to inhibit melanocytes from producing melanin and reduce melanin particles.
The experimental animal rats were used as a control substance with vitamin C, and the smeared parts were used to make tablets to observe the inhibition rate of tyrosinase. The study showed that the observation parts of ginsenosides had the effect of inhibiting tyrosinase, which further verified that ginsenosides have whitening properties. effect.
Research on anti-wrinkle effect of ginseng
The mechanism by which ginseng can delay skin aging and keep skin elastic is that total ginseng saponins can scavenge oxygen free radicals that damage cells and can act as antioxidants to a certain extent, thereby inhibiting cell apoptosis. Ultraviolet radiation can induce apoptosis of cells in vivo, and the causes of apoptosis include programmed death, gene mutation, and immunosuppression. Ginsenosides play an important role in protecting skin cells against ultraviolet radiation and inhibiting malignant transformation.
Research on the effect of ginseng on hair care and hair care
Hair growth requires many trace elements and vitamins, the lack of these substances will lead to dry and split hair. Ginseng contains a variety of vitamins and trace elements such as zinc, iron and copper, and ginseng extract is added to shampoo to make trace elements and vitamins effective. It penetrates into the hair roots, nourishes the scalp and hair strands, and promotes hair growth.
Ginseng polysaccharide helps organisms to effectively resist the radiation damage caused by radiation. Adding ginseng polysaccharide to shampoo can reduce the scalp’s exposure to ultraviolet rays in the hot sun in daily life, thereby preventing hair loss and other hair problems caused by the hot sun.
Ginseng extract can also scavenge excess free radicals and has antioxidant effects. Combined with its effect of promoting the synthesis of type I collagen, it can achieve a better anti-aging effect. In addition, the study found that in the UVB-induced fibroblast photoaging model, ginseng extract can simultaneously regulate MAPKs and NF-kB signaling pathways, inhibit the abnormal secretion of MMP-1 and MMP-13, and achieve anti-photoaging effect.
Promote collagen synthesis
Ginseng extract can significantly increase the production of type I collagen in human skin fibroblasts without cytotoxicity. Compared with the control group, ginseng extract was able to increase collagen synthesis by 55.1% at a concentration of 100 µg/mL. This study further evaluated the effect of major chemical constituents in ginseng extract on type I collagen synthesis. The results showed that Rb3 (100 µM) could significantly increase the production of type I collagen (160.2% increase) compared with the untreated control group; however, Rb2 had a weaker effect on the promotion of collagen synthesis in human dermal fibroblasts. Therefore, the experimental results prove that ginsenoside Rb3 is involved in the promoting effect of ginseng extract on collagen synthesis of human dermal fibroblasts.
