Not long ago, a female patient was seen in the dermatology department. This patient usually has the habit of applying facial masks frequently. She used the same mask continuously for two years. But in the end, her skin became more and more sensitive, and when she visited the doctor, her whole face became red and itchy, and the slightest sun exposure, or emotional excitement, would aggravate her condition. This patient was typically suffering from hormone dependent dermatitis because of the glucocorticoid mask. However, what is worrying is that in the past few years, the number of patients with hormone-dependent dermatitis has been increasing not only in Guangdong but also nationwide. Because hormones have the effect of constricting blood vessels, and the skin color is related to the hemoglobin of blood vessels, the skin will become white after the blood vessels are constricted; secondly, hormones have the effect of water and sodium retention in the body, that is, the water content of the skin will increase and it will become watery. So, after applying the mask, you feel comfortable with your skin, it looks shiny and beautiful, but in fact it is something harmful. It only takes about two weeks for hormone dependent dermatitis to develop, but treating it is a long and tricky process. The science of choosing a safe mask Compared to skin care products that cost hundreds or even thousands of dollars, sheet masks are not only affordable, but also very effective in cleaning and moisturizing, and are popular with consumers. In the e-commerce, micro business and other platforms, the types of masks, brands are a variety, and sales are amazing, in addition to the basic moisturizing mask, there are many claims with quick whitening, hydration, skin rejuvenation and other effects of the mask, so that consumers are blurred. In the face of too many problems with skin care products and cosmetics, as a dermatologist, I hope to teach you how to scientifically identify and choose a safe mask from a professional perspective. A, test the heavy metal content Find a new dime, with the upright side of the coin, scratching back and forth on the mask, if there is no change, you can initially indicate that does not contain lead and mercury, if it becomes black that contains lead and mercury, the darker the color, the higher the amount of lead and mercury! Second, test whether it contains hormones After stopping use is worse than not using. And even allergies and redness, we must consider whether hormones are at work! Third, test whether it contains preservatives If you buy a product, after opening it emits a very strong fragrance, or even, there is an abnormal fragrance, then you should be careful, such products add preservatives, fragrance, alcohol is too high, if you continue to use it will produce dermatitis, acne and other phenomena. Fourth, the official website of scientific inquiries, identification It is understood that China’s cosmetics for the implementation of registration and filing of the two management system, product registration and filing information by the State Food and Drug Administration website unified announcement for public inquiries. To identify whether a cosmetic product is reliable, consumers may want to keep an eye on it and spend two or three minutes on the website of the State Food and Drug Administration (http://www.sfda.gov.cn), enter the trademark, product name or production unit, approval number, etc., as indicated on the product package in the “Cosmetics” navigation bar, In the “Cosmetics” navigation bar, enter the trademark, product name or manufacturing unit, approval number, etc., and “check against the product at hand, and the result will be clear at a glance. “If the information found is consistent with the registration information on the website, then the product should be relatively safe and reliable; if not, the first do not buy and use, the second recommended directly to the local food and drug regulatory authorities to report, complaints, the reporting phone number is 12331.” V. Choose lead-free mercury-free hormone-free safety In the case of various additives that make the quality of the mask worrying, biological skin care products with higher safety and effectiveness have become an unstoppable trend. The biological skin care product that we are talking about today is the peptide mask. Compared with ordinary masks, peptide masks represent the safety and effectiveness of masks. It is hypoallergenic and highly safe, allowing the active ingredients to reach deep into the skin for functional skin repair and regeneration. Why peptide mask is called the real safe mask nowadays? 1.High activity: it can regulate various physiological activities and biochemical reactions. Different active peptides play different roles in the skin, according to the skin biochemical mechanism reasonable collocation, can effectively activate cells to remove free radicals, reduce wrinkles, repair damage, reduce oxidation and lighten pigmentation; regulate skin immunity, reduce collagen loss and promote cell regeneration. 2.Safety: peptide is homologous with the organism, which ensures its excellent compatibility as facial anti-wrinkle and anti-aging. 3.Quality control: each applied active peptide is a single substance, compared with plant extract, its quality is easy to control, the purity can reach more than 99%, with the characteristics of high stability, moderate action and obvious effect.
