As a dermatologist, I am concerned about protecting my skin, but I am unsure of how to protect it and how not to harm it.

Using a sponge instead of a towel and a steel ball shower shows that you are still concerned about protecting your skin.

Don't forget, though, that sponges have friction and are used to remove dust. biodegradable dish sponge Compared to steel balls, sponges are less harmful to the skin, but they can also damage it. Sponge can be okay for adults with rough skin, but it can cause enough damage for babies and young children.

As a result of the cleaning effect of shower gel, the damage is even greater.

Likewise, use facial cleanser or facial cleanser, and use weakly acidic facial cleanser that does not even foam; melamine foam bulk Wash your hair with shampoo, and use shampoo that has a weak acidity or isn't even foamy; Use hand sanitizer and use weak acid foam-free hand sanitizer; To wash the face, hair, and hands, the company does not use washing powder, but to avoid alkaline detergents.

We know from experience that foaming detergent cleans clothes better, but also makes them more "hot". bulk loofah 6 inch Foam cleansers, shampoos, and hand sanitizers are less protective of the face, scalp, and hands. As you remove ash, you lose sebum, and your skin may suffer damage.

The 21st century has passed, but some people still wash their hair and face with laundry detergent, soap, soap, sulfur soap, and so-called handmade soap.

Even hand sanitizers labeled baby sanitizer can cause damage to your opponent, especially those with foam, which means more damage if your hands dry after washing.

Face, scalp, and hands are less damaged by cleaning products with less foam.

In addition to melamine, more and more Chinese people have begun paying attention to the amount of formaldehyde released by magic friction.

There is a 50 times higher level, and the screenshot says "Secondary textiles only (direct contact with skin) /u003C 75mg/u002Fkg". Try on a piece of cloth as underwear. The formaldehyde content should not exceed 75mg/U002Fkg as per GB 18401-2010 "B direct contact with skin". This kind of fitting is too casual and meaningless.

According to the hygienic standard for formaldehyde concentration in indoor air, formaldehyde concentrations are allowed to be no more than 0.08 mg u002Fm3. We placed the nano-sponge in an airtight beaker and measured its formaldehyde concentration. In this way, you will expect your home's materials to exceed the limit. It is important to know that formaldehyde concentrations are measured in indoor air, not in a closed box where decorations are purchased.

Formaldehyde is a water-soluble and chemically unstable substance, which will dissipate before accumulating. Despite the convenience of nano sponge, previous cleaning appliances have many disadvantages (nano sponge is hard to mold, and those who have used it should know that stainless steel wire does great harm to tableware, sponges are poorly molded, and ordinary rags are breeding grounds for fungi).

It should be noted that melamine resin has been used in tableware since 1980 and was subject to national standards. These standards, known as GB9690-2009, have undergone two revisions and now include regulations on formaldehyde migration. While nano-sponges and tableware may differ, both are considered kitchen supplies made with melamine. It is important to note that there are currently no national standards for nano-sponges, so it is up to each individual to stay informed. The purpose of this standard is to determine if a nano-sponge meets the requirements, rather than simply assuming it does not meet the formaldehyde release limits. It should also be kept in mind that formaldehyde can be found in many products and may or may not exceed the standard.
