In recent years, hand sanitizer has gradually replaced soap because of its convenience and hygiene. However, studies have shown that some hand sanitizers contain antibacterial chemicals harmful to the human body, such as triclosan, which can cause damage to human thyroid gland and even kill all bacteria, and the skin over time. The bacteria on it are also "resistant".

In addition, it may also contain phthalates, polyethylene glycol, affecting reproductive health and even cancer. Therefore, be sure to rinse thoroughly after washing your hands with hand sanitizer.

When using hand sanitizer, it is best to rub your hands for more than 30 seconds, then rinse with running water for at least 15 seconds until your hands feel guilty. If you have the conditions, you can take 1 minute. Some hand sanitizers will have a slippery feeling after passing through, it is difficult to judge whether it is washed out. At this point, you can use both palms to face each other, and forcefully rub each other for a few times. If there is a thin white foam on the hand, there is still residual hand sanitizer.

Many people are afraid that the hand washing is not clean, so a large amount of hand sanitizer is put on the hand. When washing, Professor Zhang Lihua, director of the dermatology department of the Fourth Affiliated Hospital of Harbin Medical University, reminds that it is easy to damage the skin, but not to retain moisture. Will make the bacteria more intrusive. Use a small drop of hand soap every time. If the control is not good, you can put a few rounds of rubber bands under the pressure nozzle, so that the pressure nozzle will not be pressed to the bottom end, saving the amount. In addition, although many hand sanitizers contain skin care ingredients, frequent hand washing can still cause dry skin on the hands. Therefore, after washing your hands, it is best to apply moisturizing hand cream.

Need to be reminded that most hand sanitizers are only sterilized by alcohol, but alcohol can not effectively remove the dirt, such as dust, dirt, blood stains, etc., which are adsorbed in the tiny gaps of the skin, so once the hands are contaminated with such dirt, You should first wash your hands with soap and decontaminate, then use hand sanitizer to sterilize and moisturize.
