With the continuous outbreak of new coronary pneumonia, masks are indispensable.
The masks on the market are being updated, and there are more and more choices of masks in colorful colors and styles, but it is pointed out that these colored masks containing pigments are carcinogenic.
Earlier, TVB "Looking Around" commissioned an expert to conduct a test, and found that the amount of bacteria in color masks was as much as that of hand cloths in meat stalls, while carcinogens...
Under the new crown pneumonia, masks have become daily necessities.
The general medical masks are mainly blue, green and white, but now there are more and more masks of different colors and prints on the market, which is convenient for everyone to "shirts"!
In addition to Christmas approaching, many Christmas masks are on the market. Are these masks harmful to health?
Color masks contain the same amount of bacteria as the hand cloths of meat stalls. What is more, color masks can cause cancer?

Does the color mask contain much bacteria?
As early as the 1970s, an American study stated that colored dyes help bacteria grow. Based on the same principle, are colored masks more likely to grow bacteria?
The TVB program "Looking to the West" commissioned experts to test "color masks and antibacterial ability" earlier, and randomly sampled 12 masks on the market, 7 of which are color and color printing masks, and the other 5 are blue, white and black. Pure color mask.

However, experiments cannot prove that all colored masks will inevitably increase bacteria, but the results reflect that the more colorful the masks in the experiment, the higher the bacteria content measured.
Mask pigments may increase the risk of skin allergies
What is the dye of the mask?
As mentioned in the program, the main color of the mask is colored by masterbatch. The masterbatch is a combination of some resins and high-concentration pigments. The colored plastic pellets are added to the plastic and then passed through the plastic. The process of creating colored non-woven fabrics, and then processed into colored masks.
Lin Xuqiang, a specialist in skin and venereal diseases, pointed out that masks containing pigments, some substances or releasing formaldehyde, adhesives (glue) may also cause skin allergies in some people, causing itching, rashes, skin inflammation, and swelling.
In addition, when wearing a mask, the humidity and temperature of the chin and cheeks will rise correspondingly, increasing the chance of bacteria breeding. If the skin is damaged or people who have skin allergies, bacteria will invade the skin, causing bacterial infection of the skin, redness and swelling. Water seepage, pus, and skin pain.
If you feel itchy skin and other allergies after wearing a mask, you should switch to another brand of mask.

Color masks contain carcinogens?
Earlier, there were reports in Taiwan that local colored masks were tested to contain carcinogenic dyes, including excessive azo colorants.
According to the Taiwan Consumer Protection Agency, the azo pigment used to dye the mask is not necessary.
But textiles are often dyed with azo pigments, which may induce carcinogenesis through skin contact and breathing.

"Looking Around" collected 8 masks of different colors and tested the formaldehyde content and carcinogenic aromatic amine dyes.
Fortunately, the test results are reassuring. None of the 8 masks contain carcinogens azo dyes and formaldehyde.
However, if you are worried about your health, choosing a solid color mask is foolproof!
How to choose a mask?
In fact, masks in the market seldom list detailed ingredients and materials, so when you feel itchy and other allergies when wearing a mask, you should stop using it immediately.
Dr. Lin said that from the perspective of skin health, it is generally recommended that the public use surgical masks. N95 masks are more scorching and tend to cause oily skin and occlude pores, making them less suitable for people with skin problems.
