Cosmetics refer to all products which are intended to be rubbed on the external parts of the body. Cosmetics are comprised of a blend of various chemical substances derived either from natural resources or synthesized ones. Many cosmetic products are categorized under cosmetics including creams, lotions, ointments, moisturizers, sunscreens, lipsticks and foundations among others. Cosmetics manufacturers are required by law to provide warning labels on their cosmetic products regarding the potential hazards of long-term use. These warning labels are mandatory and a legal requirement for any cosmetic product that is sold across state lines or country borders.
Cosmetics can be categorized into three main categories: emulsions, gels and liquids. Emulsions are composed of two or more ingredients which are applied in an emulsion (liquid) such as oils, bases, waxes and creams. Gels are comprised of two or more ingredients which are applied topically to the skin. Moisturizers and eye shadows in addition to the foundation are examples of creams https://beecost.vn/sua-rua-mat-innisfree.html.
Cosmetics should not contain dangerous chemicals as some of these ingredients may cause allergic reactions. The Environmental Protection Agency (EPA) recommends that cosmetics are evaluated for both the concentration of toxic ingredients and the manufacturing method by using standardized computer screening methods. The substances included in cosmetics such as fragrance oils are referred to as “permanent ingredients”. These chemicals cannot be broken down in the digestive system, so they are present in the fat cells of the body. Some of these ingredients have been banned in some parts of Europe including the UK and US but are legal in other parts of the world.
Before purchasing a cosmetic product it is important to be aware of the ingredients contained in each package. The cosmetologists and cosmetic manufacturers of cosmetics often require a physician’s prescription in order to sell cosmetic products that contain prescription medications. A physician’s prescription allows a doctor to administer appropriate dosage of a cosmetic ingredient. Cosmetics that are overused or that contain high concentrations of a preservative, such as parabens, may cause adverse reactions that may include dizziness, chest pain, headaches, dry skin, or rash. In addition, products that contain alcohol should never be used by pregnant women who have breast cancer or prostate cancer.
An interesting fact about some of the ingredients found in cosmetics and beauty products is that many preservatives are derived from natural sources, such as plant extracts and oils. While synthetic preservatives like Bismuth Oxychloride are commonly used in cosmetics, it is important to read the ingredient label on any cosmetics product you plan to use. Unfortunately, it is difficult to know whether or not a preservative has been added with a “natural” label.
Many cosmetic companies claim that their products are free of harmful chemicals and that all of the ingredients in their cosmetics are natural. But, experts agree that the key word in the phrase “natural” is no longer clear. Dermatologists advise consumers to read the label on cosmetics product to ensure that the ingredient is not simply listed as a “natural” compound. They add that while compounds like Bismuth Oxychloride may be naturally occurring, they may still be hazardous.
