Is it better to use sunscreen in Japan or whitening in pola Weisi?

Hello, I'm glad to help you answer.

Whitening masks or other whitening products, especially whitening, are likely to contain fluorescent whitening agents.

Optical brightener is a fluorescent dye and a complex organic compound. Its characteristic is that it can produce blue fluorescence, which can make the substances visible to the naked eye become very white.

Take the mask as an example to test whether it contains fluorescent whitening agent. Unpack the mask, then put it under ZF-C three-purpose uv analyzer, and irradiate the mask with ultraviolet light to see if it will emit bright blue light. If yes, the mask contains fluorescent agent. If you don't have an ultraviolet analyzer, you can use an ultraviolet flashlight, an ultraviolet money detector/pen, etc.

The mask containing fluorescent agent shows a very large area of bright blue under ultraviolet irradiation. A little contact with the mask liquid will attach the fluorescent agent component, and the hand holding the mask will also have fluorescence. After washing your hands with clear water for three times, the fluorescent agent on your hands still emits strong bright blue light under ultraviolet irradiation, which can hardly be washed off. After washing with hand sanitizer for 3 times, the hand also emits blue light after irradiation, but the effect is slightly better than that of clear water. Cleaning with facial cleanser has the same effect as hand sanitizer, and it can't completely clean the residual fluorescence on your hands. ...

Harm of fluorescent agent to human body;

Fluorescent agent is not as easy to decompose as general chemical components, but accumulates in human body, which has many harmful effects and greatly reduces human immunity; The combination of fluorescent agent and protein outside the wound will also hinder the healing of the wound; Fluorescent agents will cause the variability of human cells, and their toxicity will accumulate in the liver or other important factors, which will become a potential carcinogen. Damage to blood system: Chemical substances can easily pollute human blood. Although blood has a certain self-purification ability, a small amount of harmful substances will be diluted, decomposed, adsorbed and discharged, but a large number of toxic substances will inevitably change qualitatively for a long time; Entering the blood circulation will destroy the cell membrane of red blood cells and cause hemolysis.
