What crazy cosmetics did ancient women use to turn white? Women's love for beauty has existed since ancient times. This woman can give her life for beauty.
Especially, women all over the world regard white as beauty. As the saying goes, white covers three ugliness, so the pursuit of whitening is a must for every woman.
Therefore, those cosmetics with whitening function have become the object that girls are keen on. As long as it works, even if there are side effects, many women don't mind.
The same is true of ancient women. In order to whiten your face, you dare to draw anything, which is enough.
A girl will dress herself up for a man who loves her.
Modern women love beauty, not only to show others their beautiful appearance, but also to please themselves. In other words, modern women love beauty not only by marrying men, but also by self-appreciation.
But in ancient times, the beauty of women was really just to please men.
After all, ancient women had a low status. Only by marrying a good husband and getting his love, can they be honored and loved all their lives and reach the winner in life.
Therefore, ancient women paid special attention to their beauty, which was actually linked to fate.
Or can't be beautiful, ancient women may have bad marriages and bleak lives, so ancient women had the consciousness of being ghosts before they reached adulthood.
Lead powder, an ancient whitening superstition
Ancient women had a strong demand for whitening, so many people specially studied these whitening effects, and various whitening powders were born, among which lead powder had the best effect. As long as it is painted, it will turn white immediately, which is greatly sought after by ancient women.
In modern times, some people with common sense in beauty know that this kind of whitening can't happen overnight, but any product that can whiten instantly must contain lead compounds.
Although lead can whiten quickly, it is just like opium. It worked well at first. Over time, the skin will become sensitive, fragile and brown, which is equivalent to disfigurement in disguise.
This kind of lead powder has such a good effect because it contains a lot of lead.
But even so, many women in ancient times loved to use lead powder.
Biological whitening
Of course, this lead powder is good, but the side effects are too great, which is not the best choice for whitening.
In order to meet the great demand of ancient women's whitening, and also to ensure safety and effectiveness, many strange biological masks appeared in ancient women's daily necessities.
Among them, masks made of bird droppings were deeply loved by ancient women because of their remarkable effects.
Although this biological mask is nontoxic and harmless, it has whitening effect, but after all, it is animal feces, and of course there are masks similar to animal secretions. But it's a raw material, and it feels uncomfortable. It's unacceptable to apply it to your face.
But ancient women dared to use anything, as long as it had an effect, they could whiten their skin.

Why do cosmetics contain lead? Why do cosmetics contain lead?
1. Lead powder is the base makeup in ancient women's cosmetics, with its characteristics.
In ancient China, Japan and even Britain, women would paint their faces with something called "lead powder" to make them look whiter.
The function is a bit like today's liquid foundation, powder cake, loose powder and duck egg powder.
Women have been making up in this way for a long time.
There is historical evidence.
"Yuefu Poems, Cross-wind Songs, Five Mulan Poems II" says: It's easy to dress, but the lead powder makeup is washed away.
In Tang Dynasty, Xue Neng wrote in the ninth poem of "Wu Ji": The crown cut yellow silk and purple silk, and the thin lead powder painted blue moths.
In the fourth and second chapters of A Dream of Red Mansions in Qing Dynasty, Cao Xueqin wrote: fourteen boxes of lead powder and twelve posts of rouge.
The flour used by Japanese geisha is lead powder, but now it is not lead powder.
/kloc-In the 6th century, Queen Elizabeth I liked to face as white as snow and paint with lead powder, which once led a wave of aristocratic women with fair skin.
As can be seen from the above, lead powder can only be used as a covering disposable whitening substance, which has no skin care effect and no physiological whitening effect.
2. What exactly is lead powder? What are the disadvantages?
Lead powder is actually a mixture of 60%~80% lead oxide and 20%~40% lead. It is white powder, soluble in acid and insoluble in water.
Ancient women painted their faces with its white powder to brighten their skin color.
Human skin is weakly acidic. Ancient women put lead powder on their faces, and some lead was absorbed by the human body and entered the bones and blood. Over time, it will cause chronic lead poisoning, which will cause serious damage to the blood system and nervous system of human body, even irreversible damage.
Since realizing the harm of lead to human body, not only China, but also many countries have strictly regulated the use of lead and strictly controlled the lead content in industrial products.
3. Lead powder is no longer a component of base makeup products, but lead may enter daily chemical products in the form of metal soap.
Since the industrial revolution, people's cognition of the whole world has undergone subversive changes. With the understanding of various chemical elements, pure lead powder, a hurtful cosmetic, has been abandoned.
It is replaced by talcum powder, titanium dioxide mixed with vaseline, liquid paraffin, lanolin and its derivatives, oily raw materials such as vegetable oil and silicone oil, water-based raw materials such as ethanol, glycerol and propylene glycol, surfactants, powder raw materials such as metal soap, liquid foundation and powder cake.
Although lead powder is no longer needed as the main component of base makeup, the complexity and industrialization of formula make metal soap an indispensable and stable raw material for base makeup products.
Metal soap is an indispensable raw material not only in base makeup products, but also in all daily necessities, and plays the role of stabilizer, preservative, thickener and defoamer.
In fact, there are many kinds of metal components in metal soap. Non-alkali metals such as calcium, magnesium, zinc, iron, aluminum, manganese and cobalt can replace lead-containing metal soap.
This concludes the introduction of the efficacy and function of lead powder and the efficacy and function of lead acetate powder. I wonder if you have found the information you need? If you want to know more about this, remember to collect this website.
