When many people choose hand soap or body wash, they will unconsciously choose "antibacterial" or "antibacterial" products. The reporter found that there is no scientific evidence that antibacterial soap is more effective than ordinary soap, but it will cause bacterial damage and other hazards.
Can remove 99% of bacteria? Antibacterial soaps or body washes on the market are mainly based on big brands such as Shufujia and Drip. Some antibacterial products claim that "the natural bacteria kill rate on the opponent is as high as 99%."
Wang Wei, director of the dermatology department of the First Affiliated Hospital of Tsinghua University, said that it is not necessary to use antibacterial soap, and ordinary products can achieve this effect. Because the bacteria that stay on the body surface are not directly attached to the skin cells, but adhere to the oil on the surface of the human body, ordinary soap can dissolve the oil well and remove most of the bacteria.
Can antibacterial and antibacterial? Antibacterial soap is also known as antibacterial and antibacterial effect. In this regard, Professor Sun Jianfang from the Institute of Dermatology, Chinese Academy of Medical Sciences said that there is no basis. Professor Sun explained that because antibiotics need a certain concentration and require a certain time, the antibiotic concentration is difficult to ensure when using antibacterial soap or body wash with water, especially the process of washing hands for three or two minutes is more difficult to achieve antibacterial effect.
The effectiveness of antibacterial soap was questioned by the US Food and Drug Administration as early as 2005. At the time, the panel judged with a 11 to 1 result: there is not enough evidence to prove that antibacterial soap is more effective than ordinary soap.
Can antibiotics be used casually? Some antibacterial soap ingredients contain "Triclosan" and "Triclosan". The reporter searched the literature and found that many authoritative journals included in SCI suggested that such substances may affect testosterone, estrogen and thyroid hormone levels, and there is a risk of carcinogenesis.
Sun Jianfang said that triclosan and triclocarban are broad-spectrum antibacterial agents, and clinical use of antibiotics is very cautious, because the abuse of antibiotics is likely to lead to bacterial resistance. Studies at the University of Michigan have shown that people who regularly use extra bactericidal soaps are less effective at preventing infectious diseases and lowering bacterial levels than using ordinary soaps.
Experts suggest that the key to hand washing should be to wash your hands carefully in the correct steps, do not rely too much on antibacterial soap.
The US Food and Drug Administration (FDA) has also announced a proposal to impose stricter regulations on antibacterial soap and shower gel manufacturers because long-term use of antibacterial soap may harm human health.
