Recently, reporters have found that there are many "concept sanitary napkins" on the market. On the outer packaging of these products, words such as probiotics, prebiotics, amino acids, etc. appear, claiming to promote beneficial bacteria, inhibit harmful bacteria, and have a certain regulatory effect on the female vaginal microbiota, which can maintain the balance of the microbiota. Do sanitary napkins need these 'technical formulas'? Are they really effective? On the afternoon of the 3rd, the reporter arrived at the daily necessities area of a large supermarket, where various brands of sanitary napkins were neatly arranged. In addition to different categories such as liquid sanitary napkins and sleeping pants, various dazzling words such as weak acid antibacterial, amino acids, probiotics, etc. were printed in prominent positions on the sanitary napkin packaging bags, and some even marked with words such as "adding beneficial bacteria to private parts", seemingly trying to attract consumers' attention with a "sense of technology". The reporter randomly interviewed several consumers who were making purchases in front of the shelves and found that when faced with this "fancy" promotion, their choices were more pragmatic and rational. I quite like buying new products, and the packaging looks good. Whenever I see them, I will buy them back and try them out. I have also used sanitary napkins with additives such as amino acids and probiotics, and I feel that the difference is not significant. "Young girl Xiaowan said that the main reason she repurchased some products was that they did not leak and felt refreshing and not stuffy. Of course, the price should not be too expensive. Ms. Liu, who is currently purchasing goods, told reporters that when it is inconvenient, she will also temporarily buy some other brands for "emergency", but she still looks at the brands. There were no health issues in the first place, and I never thought that some 'black technology' could improve any problems. Unlike Ms. Liu's situation, Miss Wang has been troubled by her 'sensitive skin'. I have tried many expensive sanitary pads that are suitable for sensitive skin, but they really don't work for me. Every time I get acne, it hurts even after grinding, and later I switched to cotton pads. So for me, even the most powerful 'black technology' will fail, and sanitary pads can't relieve my problems. I can only use sanitary pads, otherwise I have to go to the hospital to get a detergent and wash every day. In fact, the vagina itself is a very delicate micro ecosystem. ”Keng Yan, director of the Obstetrics and Gynecology Department at Nanjing Jiangbei Hospital, bluntly pointed out that there are multiple bacterial communities residing in the female vagina, which constrain and interact with each other to maintain local ecological balance. The vaginal microbiota itself has a strong self-cleaning function and does not require excessive external interference. For example, the core bacterial group lactobacilli maintain an acidic environment in the vagina by producing lactic acid, thereby inhibiting the growth of harmful bacteria. There are also opportunistic pathogens such as Gardnerella, Candida, and Escherichia coli, which normally maintain a dynamic balance with beneficial bacteria. Only when the body's immune system is weakened, antibiotics are abused, or improper or excessive cleaning is done, can this balance be broken, causing discomfort. "Director Kong Yan also explained the concept of" weak acidity "proposed by some brands. The acidic environment we are talking about refers more to the inside of the vagina, while sanitary pads come into contact with the skin outside the vagina. Even if the product claims to be 'weakly acidic', the possibility of directly affecting the vaginal microbiota should not be high, so consumers do not need to overly 'believe' in this. However, the standards for a truly female friendly sanitary pad are much purer than we imagine. As long as this sanitary pad is not allergic to oneself, its quality is reliable, and it meets national production standards, that is enough, "said Director Kengyan. It is recommended to prioritize using pure cotton surface and skin friendly soft materials for the material, which can effectively reduce the risk of allergies. (New Society)
