In recent years, mothers have paid more and more attention to the ingredients of skin care products and cleaning products. It is widely rumored on the Internet that parabens preservatives may cause breast cancer, eczema, allergies and other diseases. The US Food and Drug Administration also refuted this rumor, saying that not adding preservatives may cause more harm.

What is Paraben?

Mainly used as a preservative for products, this ingredient is cheap, colorless and tasteless, low in toxicity and high in acid and alkali resistance, so it is often added to cosmetics, food and medicines.

Basically, p-hydroxybenzoate is a relatively safe and low-toxicity anti-corrosion system. The most common problem is allergic reaction, the overall probability is 65,438+0 ~ 2%, and a few patients will have contact urticaria. Therefore, if you are exposed to a higher concentration of parabens, you may have a sexual reaction to the skin, but as long as the dosage is appropriate, you will be fine.

Preservatives do not cause cancer.

Regarding the rumor that parabens can cause breast cancer, the website of Food and Drug News of Food and Drug Administration emphasizes that parabens are widely used in cosmetics, medicines and foods because they can inhibit bacteria, yeasts and molds, and there is no direct research evidence to prove the carcinogenic risk of this ingredient.

As for whether adding preservatives to bath milk will cause eczema and allergies, the Food and Drug Administration said that it depends on the individual's physique. At present, there is not enough evidence to show that adding preservatives below the specified concentration will endanger human health. However, it is recommended to rinse off after using bath products to avoid residue. If a rash occurs, you should seek medical advice as soon as possible.

In Taiwan Province Province, the climate is humid. In order to prevent the product from deteriorating, preservatives must be properly added to the bath milk to reduce the risk of microbial growth. If you don't add it, the bath lotion may deteriorate and do more harm to the skin. In short, as long as preservatives are used within a safe range, there is no need to panic or worry too much.

Besides buying shower gel or handmade soap with preservatives, there are some myths about shower gel and bath lotion!

Organic, odorless bath milk is better?

Many people like "organic", "odorless" or "containing medicinal ingredients" bath products, thinking that they have better protection and are safer. However, Wu Hanmeng, a pediatrician, pointed out that it does not mean that 100% will not cause allergies, so it is ok to choose bath products with anti-allergy certification, and there is no need to be superstitious about special ingredients.

Tan Dunci, a nursing practitioner in the clinical toxicology department of Chang Gung Memorial Hospital in Linkou, said that they use more soap at home, mainly to avoid contact with the fixative in the shower gel. When she chooses a soap, she usually chooses the one with a non-lasting fragrance, because the soap with a lasting fragrance may contain artificial essence, which may cause harm to the human body.

Is it necessary to take a bath every day?

Taking a bath every day is taken for granted as a healthy concept. Elaine Larson, an infectious disease expert at Columbia University School of Nursing, pointed out that if people take too many baths, they will wash away healthy oils and beneficial bacteria, thus causing bacterial invasion. Therefore, no matter how people look and smell, it is good to take a bath once or twice a week.

However, most people still take a bath every day. Dr. Wu Hanmeng mentioned that it is good not to take a bath every day or wash their bodies with clear water, mainly to avoid the soap in the emulsion from excessively cleaning sebum, making the epidermis more fragile, and the soap is easy to skin, so there is no need to use such an extreme way. People who often sweat can choose an antiallergic bath product with pH5.5 for mild cleaning.
