For essential oils, what people hear most is "pure natural substances extracted from plants". A "pure natural" makes most people less wary when using it. Indeed, essential oil, an "elf" extracted from nature, is of little use to urban white-collar workers with high work pressure, whether it is bathing, massage or aromatherapy. It can not only improve women's skin health, but also enhance women's vitality and adjust women's physical and mental balance. However, although essential oil is good, it cannot be used at will. Essential oils are different from ordinary cosmetics, but as toxic as Chinese herbal medicines. Therefore, although the efficacy of essential oil is magical, it must be used cautiously and scientifically. Due to the high concentration of essential oil, excessive use will lead to the skin surface can not be metabolized, leading to skin burns and blackening. Many beauticians admit that customers often encounter such a situation: after buying a single formula of essential oil, they think it is better to use more, so they drop a few more drops when washing their faces, resulting in a small red pimple on their faces. Ms. Wu, an urban white-collar worker, accidentally knocked over a bottle of chamomile essential oil on her mobile phone a week ago. After a few days of rubbing, the buttons of the mobile phone became rough and the hinge part of the flip was corroded. It can be seen that while we want the beauty of essential oil, we should also pay attention to its hidden dangers. Turn it off at 1 and buy it. When buying aromatic essential oil in the store, be sure to ask about the ingredients, usage and taboos. Ordinary essential oil products should be put in dark vials, and the bottle mouth should be designed as drops. Many so-called "essential oils" sold in the market are added with mineral oil and essence, which can only be put in an aromatherapy furnace for incense. Only pure aromatic essential oils extracted from plants can be used for beauty care. 2. Be sure to go to a regular shopping mall or a monopoly chain beauty salon to buy. Pay attention to whether the label of essential oil indicates the scientific name, origin, purity, registered trademark and production date of the plant. It is best to buy the essential oil you need under the guidance of professionals. Be sure to read the instructions carefully and don't mix or mix essential oils without authorization. It's the first time to buy aromatherapy essential oil. I'm afraid it's difficult to tell the truth from the false. The grades and grades of essential oils vary greatly, and the prices of essential oils extracted from different varieties, different producing areas and different refining methods vary greatly. This is like buying tea, which is divided into many grades. The price of the same variety of tea may be different, and some tea may even be sky-high Many times it depends on personal taste and consumption values, and you can buy it when you are satisfied with it. 4. Go to several stores for comprehensive comparison, and don't buy some synthetic essential oils cheaply. Not only does it have no beauty and health care function, but it may also be harmful to the body. Before buying, ask whether the essential oil is single or compound. It is recommended to use compound essential oil, and then consult the instructions to understand its safety. To make good use of aromatic essential oil for skin care, you must first mix and dilute it with plant base oil or cream to avoid burns and irritation of allergic skin. But don't dilute aromatic essential oil with mineral oil (such as baby oil), because the molecular weight of mineral oil is too large, which will hinder skin absorption and make the curative effect disappear. If the skin has a history of allergy, when using aromatic essential oil containing phenol, the dilution ratio should be reduced (that is, reducing essential oil components and increasing base oil or cream) and the dosage should be paid attention to. Before use, a small part of skin test will be conducted, and it is usually 12 hours before we know whether it is suitable. Generally speaking, people with sensitive skin should be tested for sensitivity when using essential oils such as lemon, mint and tea tree. When using aromatic essential oil, don't touch sensitive mucous membranes, such as genitals, mouth, nostrils and eyes. If you accidentally touch it, there may be burning discomfort. Immediately dip cotton balls or makeup remover cotton into appropriate plant base oils (such as sweet almond oil and grape seed oil) and knead them repeatedly to dilute the uncomfortable parts. Individual aromatic essential oils (such as citrus) will react with ultraviolet rays and produce melanin on the skin, so it should be avoided to use on the face or sunbathe on exposed skin during the day. However, not all citrus essential oils contain photosensitive properties, and they can be used during the day: lime (distilled extraction), sweet orange, red orange, orange and grapefruit. Avoid daytime use: lime (extracted by squeezing), bergamot and bitter orange. After 36 hours of inoculation, only aromatic essential oils can be used. When pregnant, avoid using essential oils that are easy to cause miscarriage, such as taro, cypress, jasmine, chamomile and so on. Children's consumption is 1/4 or half that of adults. Please don't overdo it. Essential oils should be stored in dark glass bottles, sealed, protected from light and high temperature, and kept out of the reach of children. The following people should be careful with essential oil massage: menstrual women and pregnant women within three months of pregnancy, hypertensive patients, tumor patients, people with epilepsy history, people with skin allergies, etc.
