The consumer market continues to upgrade, and skin care products are constantly redefining themselves. Oral beauty products have become a trend in the global beauty market, and consumers have begun to realize the rise of the "inside to outside" beauty market.
Oral beauty, as a new way between ordinary skin care and professional medical beauty, conforms to the traditional concept of domestic consumers raising internally and externally, so that consumers can experience beauty skin care by "eating". From collagen, astaxanthin, enzymes to probiotics, bird's nest and other raw materials, more and more consumers are paying for such products, especially the young consumers of 90 and 95. In addition to the functional materials just mentioned, what other natural functional raw materials that exert inner beauty?
The hydrangea extract is safe for consumption. The data of acute toxicology studies in rats show that oral hot water extraction of hydrangea leaves does not produce toxicity. In traditional applications in South Korea, China, and Japan, the leaves of hydrangea are used as teas and medicines. Products made from hydrangea roots have been marketed in the United States, mainly to support urinary health.
Recently, a randomized, double-blind, placebo-controlled trial conducted in South Korea showed that oral hot water extract of hydrangea leaves (WHS) can improve wrinkles, hydration, skin elasticity and skin texture. The study has been published in the Journal of Nutrition. Compared with placebo, 300 mg per day and 600 mg of hydrangea extract per day for 12 weeks can significantly improve skin wrinkles, skin moisture and skin texture .
In this study, the researchers recruited 151 subjects and randomly divided them into three groups: 300 mg WHS daily, 600 mg WHS daily, or placebo for 12 weeks. Skin measurements were performed after weeks 4, 8, and 12, respectively. Research data show that in terms of facial wrinkles, the participants in the hydrangea group had significantly reduced crow's feet around the eyes after taking them for 8 and 12 weeks compared with the placebo group.
The improvement of skin wrinkles after WHS intake is consistent with previous studies. Early research focused on analyzing the potential benefits of hydrangea leaf extracts on human cells and hair health in hairless mice (Han et al., Nutrients 2019, 11(3), 533). Oral administration of WHS in UVB-irradiated mice can down-regulate the expression of MMPs (MMP-1 and MMP-3), thereby increasing the collagen content in the skin and reducing the formation of wrinkles.
In addition, compared with the placebo group, the experimental group's skin hydration was statistically improved after 12 weeks. Compared with placebo, the 600 mg daily dose can significantly improve the overall elasticity, net elasticity and elastic recovery to total deformation ratio.
Luo Shen Kui, also known as Roselle, is known as "Plant Ruby" for its bright red color and excellent nutritional value. It is rich in protein, anthocyanins, organic acids, VC, various amino acids, a large number of natural pigments and a variety of beneficial minerals. At the same time, it has the effects of clearing away heat and relieving heat, beauty, light spots, and hangover. Folk health care people often eat it in the form of flower tea, fruit wine, soup, preserved fruit, etc., to strengthen the body.
A study conducted in Taiwan, China, found that drinking brewed Luo Shen Kui (Hibiscus sabdariffa L.) daily may improve skin moisture while reducing wrinkles. Previous studies have shown that drinking home-grown Luo Shenkui can provide multiple benefits, such as regulating blood pressure and improving sleep quality. Based on existing research, Dr. Wang's team at Sun Yat-sen Medical University conducted a human body study to assess the effects of brewing rose hips on skin health.
The study lasted 5 months and included 60 subjects aged 25 to 85 years from hospitals and communities. The study found that drinking 200ml of brewed rose hip drink daily can increase the skin's ability to retain water and reduce wrinkles. This may be due to the role played by a series of phytochemicals contained in Roselle sunflower.
Indian Gina Tree Extract
The heartwood, leaves and flowers of the Indian Gina tree are believed to have medicinal effects, including anti-diabetic, anti-oxidant and antibacterial effects. Indians often drink water in cups made of Indian Gina trees, which are said to have anti-aging effects.
The key ingredient in the Indian Gina tree is Pterostilbene, which is chemically similar to resveratrol and has strong biological activity in the human body. Studies have shown that the raw material effectively controls blood sugar levels by inducing pancreatic cells to release insulin, which means that there are fewer factors that promote AGEs.
Pterostilbene is also a super antioxidant, enhancing the activity of various antioxidant enzymes in the skin and improving the skin's ability to defend against free radicals. It can not only reduce the oxidative damage induced by external sun exposure, but also inhibit the process of free radical-induced cell oxidation in the body. In recent years, it has become a raw material for foreign skin care products to focus on research. Clarins, Yousana, iSDG, POLA and other brands have launched The product of the raw material.
Plant ingredients can inhibit melanin synthase tyrosinase, which makes it a key raw material in product formulations, the main purpose is to lighten skin tone, such as turmeric extract (curcumin). Sabine’s SabiWhite product is tetrahydrocurcumin. This active substance can effectively inhibit tyrosinase, which is enough to slow down the production of melanin. It is more effective than kojic acid, licorice root extract and vitamin C as natural decolorizing agents. A randomized, double-blind, placebo-controlled study involving 50 subjects found that 0.25% of curcumin cream ingredients are a safe and effective alternative to the standard 4% hydroquinone cream. For local discoloration.
In addition, the water-soluble curcumin PURCUMIN® turmeric developed by Henan Zhongda, a domestic professional curcumin supplier, has the best advantages in light resistance, heat resistance, solubility, color stability and maximum bioavailability. It can be applied to tablet, oral liquid, functional beverage and other dosage forms, catering to the plant-based trend of many oral beauty products and functional food beverages on the market.
Konjac is a plant rich in glucose ceramide, which is a precursor of ceramide (Skin-Cera contains standardized 10% glucose ceramide). Clinical research has also proved the effect of the raw material on skin care, which is suitable for a variety of product dosage forms, including tablets, jelly, powder, lotion, ointment, cream and food and beverage.
Ceramide is the main lipid component of the outer layer or stratum corneum of the skin. It plays a key role in maintaining the skin barrier and structure and keeping the skin moist and soft. At the same time, ceramide beauty products have also become a popular and effective market segment in the nutrition and cosmetics market.
Over time, aging and environmental stress can significantly deplete the production and content of skin ceramides, especially in the outer layer of the skin, which can lead to dry, rough skin. By increasing the content of ceramide, consumers can see reduced skin moisture, fine lines and improved appearance of wrinkles, whether for external or internal application.
Market interest in plant-derived ceramides continues to grow, and Vidya herbs has launched a konjac-derived ceramide ingredient for this purpose. This ingredient is called Skin-Cera and has a US patent, including ingredients and methods of use (US Patent No. US10004679) .
For centuries, practitioners of Ayurvedic medicine in China and India have turned their attention to andrographis paniculata in South and Southeast Asia, emphasizing its antibacterial, antifungal, and even adaptogenic effects. Now, the market's focus has been on its most significant and unique anti-aging effects, and there is evidence to suggest the clinical mechanism of andrographis paniculata.
In one study, the topical application of this extract could increase the proliferation of epidermal stem cells and promote the production of type 1 collagen in normal human fibroblasts. The researchers found that eight weeks of treatment improved skin hydration, dermal density, wrinkles and sagging, andrographis paniculata may be an anti-aging agent. At present, Andrographis paniculata extract appears more in skin care products in the form of compounding with other raw materials. The main functions are moisturizing, antibacterial and anti-inflammatory.
More and more research evidence shows that the efficacy of traditional plant ingredients has made plant ingredients more and more popular in the internal beauty market. In addition to the plant ingredients mentioned above, collagen, hyaluronic acid, probiotics, and vegetable oils are all natural beauty ingredients that are common in life. We will wait and see whether these plant ingredients mentioned in the article will shine in the US market in 2020.
