Lipstick can greatly improve women's complexion and also increase various body functions and standards. Many people often have high requirements for lipstick. Even if they buy expensive lipstick, they find that frequent application of lipstick can easily make their skin darker. This makes people very worried about whether it will cause excessive melanin and deteriorate the quality of the skin. Whether frequent application of lipstick will cause the skin to darken is something that needs to be carefully understood. Will your lips become darker if you wear lipstick every day? Let me tell you here: Generally not! Because lipsticks from regular merchants have strict quality and hygiene standards, the pigments they contain are also within a safe range and will not cause your lips to darken or peel. The reason your lips darken may be similar to the reason your nipples and private parts darken, which is due to the influence of estrogen. Secondary sexual characteristics such as plump breasts, fair skin, and rosy lips are mainly supported by estrogen. When a woman's endocrine system is disordered, it is easy for her lips to become dark. In addition, the darkening of the areola and private parts is a sign of sexual maturity, as estrogen stimulation causes pigmentation in these areas. Although lipstick will not cause lips to darken, it does not mean that lipstick is harmful to lips, because no one can predict the harm of inferior lipstick. Although lipstick will not cause lips to darken, it does not mean that lipstick is harmful to lips. 4 major hazards of long-term use of lipstick 1. Prone to allergies. Pigments, mineral oils, antioxidants, metals and other substances in lipstick can easily become allergenic ingredients. 2. Using lipstick is more likely to absorb dust and bacteria because the lanolin in lipstick has strong adsorption properties. When people drink water or eat, the harmful substances on the lipstick will be brought into the mouth, which will affect their health. 3. Lipstick disease is prone to occur, resulting in dryness, inflammation, peeling, and slight pain. Among women who use lipstick, about 10% have developed lipstick disease. 4. Heavy metals in lipstick. Studies have found that almost all women's lipsticks contain trace amounts of toxic metals, including a high level of aluminum, which is harmful to the nervous system. In addition, heavy metals such as cadmium, cobalt, titanium, manganese, chromium, copper and nickel were also found. Therefore, the harm of lipstick still exists. Do three things to reduce the harm caused by lipstick: 1. Avoid buying products without any quality assurance, quality certification or warranty. When choosing, make sure to check the shelf life, manufacturer, production address, product ingredients, etc. 2. Pay attention to the storage of lipstick and avoid mixing it with others. 3. Lipstick is also a kind of makeup. Be sure to remove it before going to bed and use special makeup remover oil. Here I would like to remind all ladies: no matter how old you are, your lips will always be tender. Because the skin on our lips is not skin to be precise, but mucous membrane. Its physiological structure is different from that of the skin and is only 1/3 of the thickness of the skin. At the same time, there are no hair follicles, sweat glands and sebaceous glands on the surface of the lips, so they lack the nourishment of sebum, and the water loss rate is 3-4 times that of the skin, making them prone to dryness and cracking in autumn and winter. In addition, I would like to remind all ladies that lips need more sun protection. When choosing lipstick, remember to choose one with SPF or PA index. |
