After the fall, the weather is dry and the number of babies with eczema doubles. When it comes to eczema, discussions on the use of vegetable oils have also increased dramatically. “Can vegetable oil be used on children?” Everyone is concerned about this issue. There are many mothers who call for the skin care effects of vegetable oils. They believe that the all-natural formula of vegetable oils can effectively care for children’s severe eczema and is a high-quality alternative to hormones; But at the same time, some popular science articles call for caution in using vegetable oils in skin care, because improper use can cause inflammation. ThenShould we use vegetable oil for skin care? Are there any risks in using vegetable oil? Is there a better alternative? This is the most comprehensive question and answer. I hope all your questions can be answered. (This article is a long article, it is recommended to read it for 10 minutes, you can also pull it directly to the end of the article to focus on it) 1. Vegetable oil skin care can cause inflammation, is it true? “Vegetable oil” is a category. Different vegetable oils have different effects, and each vegetable oil produces different effects. As a moisturizer, booster, emollient or skin conditioner, vegetable oils are widely used in most skin care products. Normally, the vegetable oils used are safe and effective ingredients. There are hundreds of pure vegetable oils in common use, and there are dozens of derived components from a single vegetable oil. Take jojoba oil as an example. In the ingredients of regular skin care products, natural plant squeezed jojoba oil without any processing is written: jojoba (SIMMONDSIA CHINENSIS) seed oil, while jojoba is used After oil is used as a raw material for other processing, there are as many as 43 common derivatives in this category. So, there are thousands of skin care ingredients extracted from plants. Remove the vegetable oils, and the entire skin care industry is almost gone. Therefore, it is meaningless to discuss whether vegetable oils can cause inflammation. What we should know more about is: what are the common vegetable oils (the category is determined), how to use it (the usage is correct), in which scenario (the scenario is determined), and what effect it has (the effect is determined). Categories, usage, and scenarios are the premise for discussing efficacy. Without the previous confirmation, it is difficult to talk about professionalism. Where did the saying that “vegetable oils may cause skin inflammation” come from? Start with the wrong choice of category, usage, and scene. In recent years, due to its excellent skin care efficacy and nutritional value, olive oil has been touted as a skin care star in the vegetable oil industry. Olive oil comes from the fruit of the olive tree. The main components include oleic acid, a small amount of other fatty acids, such as linoleic acid and palmitic acid. More than 200 different chemical substances have been found in olive oil, including sterols, carotenoids, triols and phenolic compounds. ※Research on mice shows that topical olive oil can improve bedsores. Its active ingredients can reduce oxidative damage through anti-inflammatory and promote dermal reconstruction. ※ In the rat experiment, compared with silver sulfadiazine and saline (control) group, olive oil treatment is more efficient in promoting the contraction and healing of full-thickness burn wounds. ※ Studies have also shown that it is better to use with other essential oils, such as sea buckthorn oil and olive oil, which have a positive effect on th Phenibut on sale e skin. In a randomized controlled trial for burns, a mixture of olive oil and sea buckthorn oil proved to be an effective ingredient for treating burns, preventing infection, and accelerating tissue repair. ※ In addition, in a mouse study with UVB radiation, the researchers also found that the application of extra virgin olive oil to the skin delayed the onset of onset, and reduced the incidence of skin cancer, while Correspondingly, the formation of 8-hydroxy-2-deoxy (8-OHdG) positive cells (a biomarker of oxidative stress and cancer) is reduced. ※Research also shows that the phenolic aldehyde of olive oil has a protective effect on DNA oxidation of menopausal women and can disrupt the G1 cell cycle of colon adenocarcinoma cells and promyelocytic leukemia cells. Hydrophilic phenols are the most abundant antioxidants in olive oil. The antioxidant properties of phenolic components in olive oil are higher than vitamin E. These phenolic compounds and their antioxidant activity are added to the regular diet to show anti-inflammatory ability. In the special field of the establishment of skin barrier function, this seemingly excellent olive oil has actually received some controversial research evaluations in recent years: with olive oil in promoting and reducing skin Contrary to the positive effects in cancer development, topical application has shown to have an adverse effect on stratum corneum integrity and skin barrier function. What we call the skin barrier, mainly occurs in the stratum corneum (Stratum Corneum). The structure of the stratum corneum is like a brick wall, in which keratinocytes are surrounded by an intercellular lipid layer, like a “mortar” to maintain the integrity of the stratum corneum and barriers to skin permeability. The skin barrier function mainly depends on the integrity of the stratum corneum. Dermatitis can cause reduced stratum corneum hydration and increased transdermal water loss (TEWL). So, in clinical practice, the measurement of TEWL is used as an important indicator of skin barrier function. There is evidence that after external use of olive oil for a period of time, the TEWL index increases, showing signs of inflammation. Although skin barrier repair is an important event, olive oil may stimulate dermal remodeling by regulating early stages, such as inflammation. At present, the academic community generally recognizes that the small components in olive oil still have the function of effective anti-inflammatory activity. The above content is translated into adult words: when the amount of olive oil is moderate, it has a positive effect on anti-oxidation, anti-inflammatory, promoting the absorption of other effective substances, wound healing and even skin cancer. . But in terms of skin barrier construction, it is not the most ideal choice. But there is no need to completely block it. In fact, vegetable oil is like this. You must choose a good scene when you choose from so many types of vegetable oil. As a responsible R&D person, scene limitation comes first. What is your purpose? Whether it is anti-acne or moisturizing, anti-aging or calming, wound repair or anti-inflammation, the treatment plan in different scenarios may be slightly different or even completely different. It doesn’t matter if olive oil is not suitable for the establishment of the skin barrier, there are still a lot of vegetable oils suitable for the establishment of the skin barrier, and those are the real problems of research value. 2. I always use olive oil or tea s Phenibut on sale eed oil at home, but I haven’t found anything wrong! How can this be explained? If you do not have professional guidance and have never received relevant learning, we suggest that you “use caution” with your own edible vegetable oil for skin care products. In general, the oil extraction methods, production processes, transportation plans, and delivery methods will all have an impact on the quality of vegetable oils. If it is edible oil, we will position it as edible; and skin care products also have their own strict procedures and specifications. And if it is oil from an unknown source, there may be excessive bacterial colonies and pre-oxidation during the pressing process, and the quality and effectiveness cannot be verified. Of course, if you have professional guidance or you are a professional, using vegetable oil in the right situation will have amazing results. So if your use gives you a good experience, congratulations, maybe you just used the right method. In the use of vegetable oils, the profession of certified aroma therapist is more comprehensive in vegetable oils or essential oils You can ask them about related issues. In addition, the topic of adding olive oil as an ingredient to make skin care products is not in the scope of our discussion today. A skin care product with a mature formula system should consider ingredients, process, proportion, skin feel, stability, raw material level, etc. Only in terms of ingredients, most vegetable oil ingredients added in low amounts can be positively affirmed. 3. Is vegetable oil really beneficial to the skin barrier building? Are there any arguments for evidence-based medicine? Vegetable oils have been used for beauty and medical purposes for a long time. Most vegetable oils can protect the skin barrier to keep the skin hydrated and reduce transdermal water loss. In addition, topical skin care oil has high bioavailability and has a local effect on the skin without causing systemic effects on the whole body. Research on vegetable oils has shown that sweet almond, jojoba, soybean oil and avocado oil, when applied topically, contribute to stratum corneum hydration. (Hydration ability of the stratum corneum is the ability of cells to regulate the ingress and egress of substances, and is a more important indicator of the integrity of the skin’s barrier in addition to “transdermal water loss”) Phenolic compounds and tocopherols (vitamin E) in vegetable oils show Antioxidant effects can regulate physiological processes such as skin barrier stability, inflammation, and water loss. When applied topically to hairless mice, dl-α-tocopheryl-6 sodium-phosphate, a water-soluble vitamin E derivative (dl-α-tocopherol), enhances Ceramide synthesis and gene expression of differentiation markers (glutaminase 1, angle 10, involucrin and loricrin). Phospholipids are another component of vegetable oils, mainly fused with the outer lipid layer of the stratum corneum, and can be used as a permeability enhancer for other effective substances. In the study of a mouse specific dermatitis model supplemented with dietary phospholipids, phospholipids regulate the covalent bond ω-hydroxy nerves in the epidermis to strengthen the skin barrier, display anti-inflammatory effects, and reduce thymus Activates the gene expression of chemokine (TARC) and thymotropin (TSLP). Even if it does not penetrate deeper epidermis, the occlusive effect of topical application of vegetable oils can reduce water loss in the stratum corneum and regulate the proliferation of Phenibut Manufacturers keratinocytes. Vegetable oils extracted from plants should be strictly divided into essential oils and fixed oils. This article focuses on the fixed oil, which is characterized by non-volatile at room temperature. Although there are different ways to obtain vegetable oils, cold-pressed vegetable oils have more comprehensive nutritional properties than refined vegetable oils. This is because the cold pressing procedure does not involve heat and chemical treatment, and will not change its composition and therapeutic effect. Fixed vegetable oil components include triglycerides, free fatty acids, tocopherols, sterols, alcohols, phospholipids, waxes, squalene compounds, etc. When these different compounds are topically applied to the skin, they have different positive effects on the skin barrier, inflammation state, antioxidant response and proliferation. The potential benefits of topical application of vegetable oils are diverse. Physiological response is the result of the interaction between biologically active substances and the pathophysiological environment of the skin. The effect of topical application of vegetable oil on skin pathology. 4. Since vegetable oil is so useful, there are massive evidence-based research reports. Why is it not recommended by mainstream hospitals or doctors? Actually, “skin care” and “hospital treatment” have their own advantages and characteristics from their focus to the method of use. For example, in the field of skin care products, the use of hormones is strictly prohibited. We use natural substances and biological moisturizing ingredients to condition the skin and maintain the skin barrier. But from the perspective of western medicine pathology, the use of hormones for eczema skin is a very conventional and effective treatment. Imagine that when you hold a baby with eczema, you come to the doctor and ask, “Can I use vegetable oil for skin care?” Most doctors’ expressions should be dumbfounded. The doctor can’t give you definite advice, because he can’t be sure what kind of vegetable oil you used in which way. For general doctors, he also knows very little about vegetable oil, let alone ask him to give specific advice. In fact, the whole range of vegetable oil disciplines is more extensive. From home care, skin care products to medical supplies, research is still in progress. This kind of problem is beyond the scope that doctors can advise. So we can learn more about the skills of home care and skin care here, and less trouble for doctors. Hahahaha~In addition, the key to daily care for eczema is moisturizing, so the most basic moisturizer recommended by hospital doctors is the most basic moisturizer. However, if such basic moisturizers are analyzed in the entire skin care field, there will be a lot of better quality, more sophisticated ingredients, more comprehensive functions of infant skin care products. Therefore, skin care product brand evaluation is not the scope of this article. Mark the key, mark the key, mark the key! ? As a category, vegetable oil has a positive effect on the establishment of skin barrier, anti-oxidation, anti-inflammatory, sun protection, wound repair, etc.;? Individual oils, such as olives Oil, camellia oil, and pure oil application will have adverse effects on the skin barrier building; you can choose oils that are more conducive to the skin barrier building such as jojoba oil for children or people with eczema;? Edible Oil is not recommended to be used in skin care without professional ability or guidance;? Plant skin care is a skill suitable for self-care and home care, and it also has high research value. Learn to understand such skills. It can help everyone deal with the daily situation of themselves, their children and their families more calmly.
